Your FREE FAA Part 107 Practice Test 2026 – 280+ Q&A

Correct answer: 400 ft AGL

The Part 107 ceiling is 400 ft AGL: 14 CFR 107.51 limits a small unmanned aircraft to 400 feet above ground level, or higher only within a 400-foot radius of a structure. 400 ft HAE is height above the WGS-84 ellipsoid, the raw GPS figure many drones log, which can differ from ground height by well over a hundred feet. 400 ft AFE is above field elevation, an airport traffic-pattern reference, not the ground beneath the drone. 400 ft HAA is height above airport, an instrument-approach minimums term, not a Part 107 limit.

Correct answer: age 16

The minimum is age 16: 14 CFR 107.61 requires an applicant for a remote pilot certificate with a small UAS rating to be at least 16 years old. Age 14 is the student pilot minimum for gliders and balloons. Age 17 is the minimum for a private pilot certificate in airplanes. Age 23 is the minimum for an unrestricted airline transport pilot certificate. None of those manned-certificate ages governs Part 107 eligibility.

Correct answer: Every 24 months, after a course refresher

Under 14 CFR 107.65 a remote pilot stays current by completing recurrent training every 24 months, after a course refresher, meaning the free FAA online recurrent training within the previous 24 calendar months. Every 24 months after a knowledge retest was the rule before April 2021, when an in-person recurrent test was required. Every 36 months after a knowledge retest borrows the three-year registration period. Every 24 months after a flight review is the Part 61 manned-pilot requirement.

Correct answer: Obtain a written waiver from the FAA

The pilot must obtain a written waiver from the FAA. 14 CFR 107.39 forbids operating over a human being who is not a participant and not under cover, so a flight across a crowded area is unlawful unless the FAA grants relief. A NOTAM to the ARTCC is a notice to other airmen and grants no permission; Part 107 does not require one. A COA is the authorization path for public aircraft operators, and LAANC issues airspace authorizations rather than COAs, so neither applies to a civil operation over people. A call to a tower over the CTAF reaches nobody who can relieve the operator of 107.39.

Correct answer: File a written report with the FAA within 10 days

The pilot must file a written report with the FAA within 10 days, because 14 CFR 107.9 sets a 10-calendar-day deadline for any accident involving serious injury, loss of consciousness, or at least $500 of damage to property other than the aircraft. Fourteen days is the deadline for updating a drone registration after a change, not an accident report. Thirty days is the deadline for an airman to report a change of mailing address. Sixty days matches no Part 107 reporting deadline, so a report filed then is late.

Correct answer: Never; an ATC authorization is always a strict legal rule

There is no such condition: never; an ATC authorization is always a strict legal rule. 14 CFR 107.41 bars operation in Class B, C, or D airspace, or within the lateral boundaries of the surface area of Class E designated for an airport, unless the FAA has granted prior authorization, which for most sites is issued through LAANC or the FAA DroneZone portal. Holding a flight under 400 feet satisfies the separate altitude ceiling of 107.51 and does nothing about 107.41. Tower hours are irrelevant: the airspace keeps its Class C classification for one night and for every night after, and the authorization requirement stays with it. A plan that omits all Class C entry describes an operation outside Class C altogether, so it answers a different question than the one asked.

Correct answer: 87 kt

Section 107.51(a) caps groundspeed at 87 knots, which the rule glosses as 100 miles per hour, so 87 kt is the answer. 75 kt comes from treating 87 as miles per hour and converting it to knots. 61 kt is the Part 23 stall speed limit for light single-engine airplanes, not a drone speed cap. 54 kt comes from reading the 100 figure as kilometres per hour and converting it.

Correct answer: The remote pilot in command for the whole operation

Under 14 CFR 107.19 the duty belongs to the remote pilot in command for the whole operation, who is directly responsible for and the final authority on the flight. The responsible person named on the flight's waiver oversees waiver compliance but is not the operating authority. The air traffic controller who cleared the airspace grants authorization, not responsibility for the aircraft. The certificated person at the flight controls may fly only under the remote pilot in command's supervision.

Correct answer: In response to a sudden in-flight emergency onboard

A deviation is lawful only in response to a sudden in-flight emergency onboard: 14 CFR 107.21 lets the remote pilot depart from Part 107 to the extent needed to meet it, with a report on FAA request. An urgent ground emergency below you is not an in-flight emergency; flying to support one needs a Special Governmental Interest waiver. A first responder's emergency request carries no authority to waive FAA rules. A waiver request still pending review authorizes nothing until the FAA grants it.

Correct answer: 55 lb

The limit is 55 lb: Part 107 covers unmanned aircraft weighing less than 55 pounds at takeoff, including everything on board. 55 kg keeps the number but swaps the unit, which would allow roughly 121 pounds. 25 kg is the maximum takeoff mass of the EU open category, not the FAA rule. 249 g sits just under the 250 g line where registration becomes required, which is a registration threshold rather than the Part 107 maximum.

Correct answer: 8 hours after the pilot finishes the last drink

The regulation, 14 CFR 91.17 as applied by 107.27, sets the minimum at 8 hours after the pilot finishes the last drink, alongside the separate 0.04 blood alcohol limit. Ten hours of rest before the next flight is the Part 117 airline rest rule, not an alcohol rule. Twelve hours from the final drink is a common airline company policy that exceeds the federal minimum. Twenty-four hours is a stricter operator or military standard, not the minimum the FAA requires.

Correct answer: 0.04 percent or higher on a blood alcohol test

A person may not manipulate the controls of a small unmanned aircraft with 0.04 percent or higher on a blood alcohol test. 0.08 percent is the common highway driving limit rather than the aviation figure, 0.02 percent is a workplace testing threshold used elsewhere in transportation, and a merely detectable trace is below the regulatory disqualifier even though flying while impaired is separately prohibited.

Correct answer: Drowsiness and a delayed reaction to a conflict

Sedating antihistamines such as diphenhydramine commonly cause drowsiness and a delayed reaction to a conflict, which is why the FAA warns against flying while the drug is in effect. Tunnel vision and a loss of the sense of colors are classic signs of hypoxia, not antihistamine sedation. Tingling fingers and a racing, shallow breath describe hyperventilation. A racing pulse and a jump in the blood pressure are stimulant effects of decongestants such as pseudoephedrine.

Correct answer: Stay grounded and wait until the drug course ends

The right action is to stay grounded and wait until the drug course ends, because 107.17 bars operating while the pilot knows or has reason to know that a condition or medication would interfere with safe operation. Staying grounded only while the pilot feels drowsy relies on self-assessment, which the impairment itself distorts. Waiting eight hours after the last dose borrows the alcohol rule, and many medications act for much longer than that. Waiting until the very first dose wears off ignores the doses that follow while the course continues.

Correct answer: It dulls motor skills and judgment, making fatigue worse

Alcohol is a depressant: it dulls motor skills and judgment, making fatigue worse, because its impairment stacks on top of the tiredness the pilot already has. It does not work as a stimulant masking fatigue; the early lift people feel is disinhibition, not alertness. It does not raise blood sugar toward a steep later crash; alcohol tends to lower blood sugar. And it does not improve sleep quality or mask next-day fatigue; it may hasten sleep onset but fragments sleep, so the pilot wakes less rested.

Correct answer: Until the effects of the medicine have worn off

For an impairing drug the wait runs until the effects of the medicine have worn off, since drugs differ widely in how long they act. A fixed 4 hour clock appears nowhere in the rule, the 8 hour figure belongs to alcohol rather than to drugs, and a blanket twenty four hour wait is neither required nor proof that the effects have passed.

Correct answer: Slower reactions and clumsy control of the sticks

Hypoxia starves the brain of oxygen, and slower reactions and clumsy control of the sticks are a key symptom that alcohol makes worse by reducing the body's ability to use oxygen. Deep joint pain when flying too soon after a dive is decompression sickness. Sharp sinus pain and pressure in a sudden descent is sinus barotrauma from a pressure change. Muscle cramps and heavy thirst in the hot sun point to dehydration and heat stress.

Correct answer: Ahead of each flight as routine practice

Fitness to fly is checked ahead of each flight as routine practice, using a self assessment such as the IMSAFE checklist, because illness, medication, stress, alcohol, fatigue and eating change from one flight to the next. Checking only before the first flight of each duty day misses conditions that develop later in the day. Checking only before each flight conducted over people ties the check to one operation type. Every 24 months with recurrent training is the knowledge-currency cycle, not a fitness check.

Correct answer: Hand the controls to a fit pilot or land the aircraft now

Under 107.27 and 91.17 an impaired person may not act as a crewmember, so the pilot must hand the controls to a fit pilot or land the aircraft now. Handing the controls to the visual observer, whether to land at once or while you talk them in, leaves an uncertificated person flying under an impaired pilot's supervision, which 107.12 does not allow. Letting the visual observer act as pilot has the same defect, since an observer is not a remote pilot.

Correct answer: Impaired thinking and slower control of the muscles

The primary danger of prescription painkillers is impaired thinking and slower control of the muscles, the sedating effects that degrade judgment and reaction time and make the pilot unfit while they last. Racing thoughts and jittery control over the sticks describe a stimulant such as a decongestant, not a painkiller. A racing pulse and shaking hands on the flight sticks are also stimulant effects. Nausea and an upset stomach can occur, but they are a side effect, not the primary flying danger.

Correct answer: To confirm the aircraft is fit for safe flight

A preflight inspection exists to confirm the aircraft is fit for safe flight, as 107.15 and 107.49 require. Confirming the launch area is clear of hazards and the airspace is free of air traffic belong to the 107.49 assessment of the operating environment, not the inspection of the aircraft. Confirming the crew was briefed on the hazards is the separate 107.49 crew briefing duty, which a pilot can complete perfectly while flying a damaged aircraft.

Correct answer: The propellers' balance and any cracks or visible nicks

A propeller preflight checks the propellers' balance and any cracks or visible nicks, because a damaged or unbalanced blade causes vibration and can fail in flight. Faded or worn tip-paint warning stripes are a manned-aircraft visibility item, not a structural check on a small drone propeller. Oil seeps or grease at a hub seal belong to variable-pitch manned propellers; drone propellers have no oil-filled hub. Paint gloss and UV fading are cosmetic and say nothing about whether the blade is airworthy.

Correct answer: Withdraw the swollen battery from operations

Correct answer: Withdraw the swollen battery from operations. Swelling means a lithium-polymer cell has vented gas internally, which is permanent damage, so the pack comes out of service and is replaced rather than flown again. Recharging it for observation still forces current into a cell whose separator has already failed, and watching a charging pack does not make it airworthy. Discharging it for inspection lowers the state of charge but leaves the swelling and the fire risk exactly where they were, so the pack remains unusable. Rebalancing it through charge cycles corrects a voltage mismatch between healthy cells, and swelling is chemical decomposition rather than a balance error, so no number of cycles restores the pack.

Correct answer: Recording the aircraft weight and balance

Correct answer: Recording the aircraft weight and balance. Weight and balance is a planning computation the remote pilot works out before touching the aircraft, so it sits outside the hands-on inspection this item asks about. Checking the propeller blades and shrouds is squarely part of that inspection, since chipped blades and cracked guards are the commonest airworthiness discrepancy on a small multirotor. Verifying the control linkages and servos belongs to it as well, because free and correct movement must be seen before launch. Inspecting the airframe and camera gimbal is the same walk-around, covering loose fasteners, cracks and payload mounting.

Correct answer: To apply current software safety features and flight parameters

Checking for updates matters because the purpose is to apply current software safety features and flight parameters, such as firmware fixes and revised geofence data. No FAA rule requires the latest airspace data to be loaded on the aircraft, so loading it is good practice, not a legal condition. An update does not recalibrate the compass and IMU sensors, which is a separate procedure. And no software can unlock controlled airspace with no FAA approval; authorization comes through LAANC or DroneZone, not the firmware.

Correct answer: Replace or repair the component before departure

The pilot should replace or repair the component before departure, because 14 CFR 107.15 bars operating unless the aircraft is in a condition for safe operation. Reporting the component to the FAA before departure is not required; FAA reports cover accidents, not maintenance findings. Requesting a waiver for the defect fails because 107.15 is not on the waivable list. Logging the defect and limiting the flight to one hover still flies a known unsafe part.

Correct answer: Signal strength and solid connection of the communication link

The preflight check is signal strength and solid connection of the communication link: the aircraft and controller should be bound and the link steady for the planned range. Part 107 pilots do not need an FCC license or frequency filing for common control links. A transponder squawk and ADS-B output are not part of the link, and 107.53 bars ADS-B Out for most operations. Tower frequency and call sign checks concern a radio, not the UAS link.

Correct answer: Run the software diagnostic on the camera payload

Correct answer: Run the software diagnostic on the camera payload. The built-in diagnostic interrogates the sensor, the gimbal drive, and the data path and reports faults while the aircraft is still on the ground, which is what a preflight functional check has to do. Inspecting the protective lens addresses surface contamination and cannot reveal a dead sensor, a failed gimbal motor, or a corrupt image pipeline. Recalibrating the gimbal axes adjusts stabilization rather than testing whether the sensors respond, and calibrating a faulty unit proves nothing. Reviewing the archived imagery shows what the camera did on an earlier flight and says nothing about its condition now.

Correct answer: Cancel the mission and repair the control system

A flight control failure found on preflight means the aircraft is not in a condition for safe operation under 107.15, so the pilot should cancel the mission and repair the control system. Reporting the fault to the FAA first is wrong, because only accidents with serious injury or over $500 of damage must be reported. Recalibrating and flying the route launches with an unconfirmed fault. Switching to ATTI mode and flying by hand still launches a known-defective aircraft.

Correct answer: To confirm safe operation in the existing conditions

Weather is checked to confirm safe operation in the existing conditions, since 14 CFR 107.49 requires the remote pilot to assess the operating environment, including local weather, before flight. Part 107 sets no 1,000 ft VFR ceiling; that is a Part 91 basic VFR figure. The 1 SM Class G visibility comes from Part 91, while Part 107 requires 3 SM. The 5 SM figure applies to Part 91 flight in Class E above 10,000 feet, not to small UAS.

Correct answer: 3 statute miles of minimum flight visibility

Section 107.51(c) requires 3 statute miles of minimum flight visibility, observed from the control station. 3 statute miles of airport ground visibility has the right number but the wrong kind of visibility, since an airport report says nothing about the view from the control station. 1 statute mile of minimum ground visibility and 1 statute mile of reported ground visibility borrow the Part 91 Class G daytime figure and also measure the wrong visibility.

Correct answer: To verify the aircraft is in airworthy condition

Under 14 CFR 107.15 and 107.49 the preflight check exists to verify the aircraft is in airworthy condition, meaning in a condition for safe operation. Verifying the aircraft log has a current annual fails because Part 107 sets no annual inspection or logbook requirement. Verifying the aircraft has its annual inspection repeats that manned-aircraft Part 91 idea. Verifying the control link and GPS lock are good is only one item within the airworthiness check, not its purpose.

Correct answer: When the route stays above sparsely populated ground

Correct answer: When the route stays above sparsely populated ground. 14 CFR 107.25 permits operation of a small UAS from a moving land or water vehicle, but the operation must be over a sparsely populated area, which is what keeps the risk to people on the ground acceptable while the control station itself is in motion. Whether the flight happens within lawful daylight hours governs lighting and civil-twilight requirements and has nothing to do with permission to fly from a vehicle. Whether the nearby airspace registers a single aircraft concerns traffic separation, and an empty sky does not lift the sparsely populated condition. Whether a qualified observer travels inside the vehicle is useful practice, but an observer does not substitute for the population limit, and carrying property for compensation from a moving vehicle stays prohibited.

Correct answer: Allow 500 feet below and 2000 feet horizontally

Correct answer: Allow 500 feet below and 2000 feet horizontally. 14 CFR 107.51(d) requires the small unmanned aircraft to stay at least 500 feet below any cloud and at least 2,000 feet horizontally from any cloud, so the remote pilot keeps clear vertically and laterally at the same time. Leaving 400 feet below and 1000 feet horizontally borrows the 400-foot altitude ceiling of 107.51(b) and halves the lateral figure, so it fails both halves of the cloud rule. Keeping 1000 feet below and 2000 feet horizontally applies the 1,000-foot figure that manned VFR pilots use for clearance above a cloud, not below one. Holding 2000 feet below and 1000 feet horizontally simply reverses the two distances, which leaves the aircraft far too close laterally to a cloud that can hide converging traffic.

Correct answer: When a 0.55 pound aircraft has no exposed cutting rotors

Without a waiver, a remote pilot may fly over people when a 0.55 pound aircraft has no exposed cutting rotors, which is Category 1 under 14 CFR 107.110: 0.55 pounds or less including everything attached, and no exposed rotating parts that would lacerate skin. A 0.55 pound aircraft that merely broadcasts a Remote ID signal still needs the no-exposed-rotor condition. A 55 pound aircraft broadcasting Remote ID fails the weight limit entirely. A 55 pound aircraft with ducted rotors also exceeds the Category 1 weight.

Correct answer: 0 months, because Part 107 sets no retention requirement

The answer is 0 months, because Part 107 sets no retention requirement: the rule imposes no maintenance record-keeping duty for small unmanned aircraft, so the remote pilot in command breaks nothing by discarding the paperwork, although keeping it is sound practice and manufacturers often ask for it. The 12 month figure borrows a medical-certificate style interval, and remote pilots hold no medical certificate under Part 107. The 24 month figure echoes the 24 calendar month recurrent training cycle, which governs the certificate holder rather than the aircraft records. And the 6 month figure matches no Part 107 interval at all, since disposal is unrestricted from the first day.

Correct answer: 8 hours between the last drink and takeoff

The required wait is 8 hours between the last drink and takeoff, because 14 CFR 107.27 applies the 91.17 alcohol rule to small UAS operations. A 10-hour gap confuses the drinking rule with the 10-hour rest period found in the commercial crew-rest rules. A 12-hour gap is a stricter company or military policy, not the Part 107 minimum. A 24-hour gap is a personal guideline that no federal rule sets. Separately, a pilot may not operate with a blood alcohol concentration of 0.04 or more.

Correct answer: 120 calendar days of temporary certificate status

Correct answer: 120 calendar days of temporary certificate status. 14 CFR 107.64(a) issues the temporary remote pilot certificate for up to 120 calendar days, by which time the permanent certificate is issued to an applicant the Administrator finds qualified, and 107.64(b) ends it sooner if the permanent certificate arrives or the application is denied. 30 calendar days of official qualification status matches no FAA issuance rule and would expire long before normal processing finishes. 60 calendar days of restricted eligibility status likewise appears nowhere in the certification rules and confuses the certificate with a short administrative grace period. 90 calendar days of conditional privileges status is the interval people most often guess, but the parallel airman rule at 61.17(a) also uses 120 days, not 90.

Correct answer: 12 months from the final conviction date

Correct answer: 12 months from the final conviction date. 14 CFR 107.57 makes a drug or alcohol conviction grounds for denying a remote pilot certificate application for a period of one year after the date of final conviction, so 12 months is the interval the rule names. 6 months from the documented arrest date is wrong twice over: it halves the period, and the clock runs from conviction rather than from arrest. 18 months from the suspended permit date borrows from state driver-license practice, and a suspended driving permit is not the event the federal rule keys on. 24 months from the written judgment date doubles the federal period and echoes the 24 calendar month recurrent training cycle, which has nothing to do with certificate eligibility after a conviction.

Correct answer: To ensure an exact GPS heading and accurate route navigation

Compass calibration is done to ensure an exact GPS heading and accurate route navigation, because the magnetometer tells the flight controller which way the aircraft points so it can hold a track and return home correctly. Satellite lock and the home point come from the GPS receiver, and calibrating the compass does not make them faster. Altitude and height hold depend on the barometer. Tilt and level hover depend on the IMU's accelerometers and gyros, which have their own calibration separate from the compass.

Correct answer: Correct the flagged entries before the next flight departure

Correct answer: Correct the flagged entries before the next flight departure. Explanation: The remote pilot in command is responsible for determining the aircraft is in a condition for safe operation, so an open discrepancy has to be resolved and the resolution recorded before the aircraft flies again. Sending the entries to the manufacturer may be a sensible parallel step but it hands the airworthiness decision to someone who is not the pilot in command and does not clear the aircraft. Judging a discrepancy small enough to skip is exactly the reasoning that lets a cracked arm or a swollen cell reach the air. Rescheduling only moves the same unresolved defect to a later launch.

Correct answer: To examine the airframe for damage produced by the flight

A post-flight inspection exists to examine the airframe for damage produced by the flight, such as cracked props, loose fasteners or a swollen battery, before the next launch. Recording each flight in an FAA-required post-flight log is wrong because Part 107 requires no such log. Checking the flight log for autopilot errors is data review, not a physical inspection. Letting the battery cool before recharging is a charging practice, not the reason the airframe is inspected.

Correct answer: Within 10 calendar days, the accident clock 14 CFR 107.9 sets.

The answer is within 10 calendar days, the accident clock 14 CFR 107.9 sets. The remote pilot reports to the FAA any sUAS operation causing serious injury, loss of consciousness, or more than $500 of damage to property other than the sUAS. Fourteen days is the Part 48 deadline to update drone registration details, not an accident report. Thirty days is the change-of-address window for a remote pilot certificate. Sixty days is the deadline to report a motor vehicle alcohol or drug action.

Correct answer: Registration covers Part 107 drones at whatever weight, with numbers marked plainly outside.

A small unmanned aircraft flown under Part 107 must be registered whatever it weighs, and the unique registration number has to be legibly marked on an exterior surface of the aircraft under 14 CFR Part 48. There is no 25 pound registration threshold, and a certificate kept indoors does not mark the aircraft. The 0.55 pound threshold applies to recreational flyers rather than Part 107, and current Part 48 marking rules require an exterior surface rather than an enclosed compartment. Registration is not voluntary for commercial work.

Correct answer: Request an FAA Certificate of Waiver, with proof the flight remains safe.

Visual line of sight under 14 CFR 107.31 is a waivable rule, so the lawful route is to request an FAA Certificate of Waiver, with proof the flight remains safe, under 107.200 and 107.205. A LAANC authorization grants access to controlled airspace near airports and cannot waive the visual line of sight rule. An FAA airspace authorization under 107.41 likewise covers only airspace, not BVLOS flight. Filing a NOTAM with Flight Service publishes the operation but authorizes nothing.

Correct answer: Age 16, plain English fluency, a knowledge test, plus TSA checks, per 107.61.

Under 107.61 an applicant needs age 16, plain English fluency, a knowledge test, plus TSA checks. Age 16 with a valid pilot license and a flight review describes the alternate path for Part 61 certificate holders, who also complete online training, not the general minimum. Age 17 is the private pilot minimum, and Part 107 requires no basic medical exam. The rating is never earned by a flight review alone, and the security vetting is done by the TSA, not the FBI.

Correct answer: One free FAA online refresher each 24 calendar months, per 107.65.

The current rule is one free FAA online refresher each 24 calendar months, per 107.65; since April 2021 the online recurrent training replaced the proctored recurrent knowledge test, so the proctored recurrency test is the old rule. A flight review with a CFI every 24 calendar months is the manned-aircraft requirement of 14 CFR 61.56, not Part 107. Three takeoffs and landings in 90 days is the 61.57 passenger-carrying recency rule for manned aircraft and plays no part in remote pilot currency.

Correct answer: Within 8 hours after alcohol, under residual influence, or at 0.04% BAC.

Section 107.27 applies 91.17, which bars acting as a crewmember within 8 hours after alcohol, under residual influence, or at 0.04% BAC. The 12-hour options keep the right 0.04 figure or borrow 0.02 but use the common company bottle-to-throttle policy instead of the regulation's 8 hours. The 0.02% figure is the DOT testing threshold for removal from duty, not the 91.17 limit. The 24-hour wait is a frequently recommended personal minimum, not the rule.

Correct answer: No FAA report, because the lower of the two shed costs is under $500

Correct answer: no FAA report, because the lower of the two shed costs is under $500. Under 14 CFR 107.9, property damage is reportable only when it exceeds $500 to repair or replace, whichever is lower, and AC 107-2A gives this exact case: a $600 repair on property worth $200 is not reportable. Pointing to the $900 repair estimate ignores the lower-of rule, and the destroyed aircraft never counts because 107.9 covers only property other than the small unmanned aircraft.

Correct answer: The handoff may happen in flight, leaving one remote PIC at a time

Correct answer: the handoff may happen in flight, leaving one remote PIC at a time. AC 107-2A says one certificated pilot may be designated remote PIC at the start and another may take over during the operation by positively communicating the transfer, provided both can keep visual line of sight; the pilot who assumes the role then holds sole responsibility. Making both pilots PIC at once is wrong because 107.19 gives final authority to a single remote PIC, and nothing requires landing first.

Correct answer: An undue hazard to persons or property

Correct answer: an undue hazard to persons or property. 14 CFR 107.23(b) prohibits allowing an object to be dropped in a manner that creates an undue hazard to persons or property, so a drop is legal when it does not. Severe harm is the most common wrong pick, but it is not the regulatory standard, and 'foreseeable risk' or 'unreasonable danger' are paraphrases that do not appear in the rule.

Correct answer: A 7 lb parcel, flown in VLOS from the store roof to a buyer in the same state

Correct answer: the 7 lb parcel flown from the store roof to a buyer in the same state, because 47 + 7 = 54 lb stays under 55 lb. AC 107-2A limits property transport for hire to a total weight under 55 lb, within VLOS, wholly within one state, and never from a moving vehicle. The 9 lb parcel makes 56 lb, which is no longer a small unmanned aircraft, while the state-line and moving-van flights break the single-state and moving-vehicle limits.

Correct answer: A written report of the deviation, but only if the FAA requests one

Correct answer: a written report of the deviation, but only if the FAA requests one. 14 CFR 107.21 lets the remote PIC deviate from any Part 107 rule to the extent needed to meet an in-flight emergency, and requires a written report only upon the Administrator's request. The 10-day deadline belongs to the 107.9 accident report, which is not triggered here because no one was injured and nothing was damaged.

Correct answer: Yes, because the VO's watch meets the VLOS rule while the RPIC checks the display

Correct answer: yes, because the VO's watch meets the VLOS rule while the RPIC checks the display. Under 14 CFR 107.31(b) the see-and-avoid duty may be exercised either by the remote PIC and the person at the controls or by a visual observer, and AC 107-2A says using a VO lets the PIC conduct other duties such as checking displays. The PIC must keep the capability to see the aircraft but need not watch it every second, and a VO needs no remote pilot certificate.

Correct answer: 14 days for the sale, and 14 days for the new address

Correct answer: 14 days for the sale, and 14 days for the new address. 14 CFR 48.115 requires the certificate holder to update the registry within 14 calendar days of any change in the registration information, such as an address, and of any event requiring cancellation, including sale, transfer, destruction or export. The 30-day figure is a real Part 48 number, but it is the period after a registrant's death in 48.100(d)(4), not the deadline for a sale or move.

Correct answer: June 15, 2026

14 CFR 48.115(b) requires the certificate holder to update the web-based registration system within 14 calendar days when registration must be cancelled for a sale, transfer, destruction or export, so a June 1 sale must be reported by June 15, 2026. June 19 counts 14 business days instead of calendar days. June 22 applies the 21-day notice that Part 47 sets for manned aircraft, and July 1 borrows the 30-day period that ends a registration after the holder's death.

Correct answer: A foreign aircraft permit issued by DOT under Part 375

A foreign-registered drone used for commercial work in the United States needs economic authority, a foreign aircraft permit issued by DOT under Part 375 (14 CFR Part 375), and the operator must still follow the FAA operating rules. A U.S. registration certificate under Part 48 is the tempting choice, but 48.20 and 48.120 make a drone already registered in another country ineligible for U.S. registration. Part 107 waivers relieve specific operating rules, not foreign status, and a Section 44807 exemption is the path for aircraft that cannot fit Part 107, not for foreign ownership.

Correct answer: The buyer must have the UK registration ended, since a foreign registration bars it

Under 14 CFR 48.20 a small drone may be registered in the United States only when it is not registered under the laws of a foreign country, and 48.120 makes a registration invalid if the aircraft is registered abroad, so the buyer must have the UK registration ended first. A DOT foreign aircraft permit and FAA recognition of ownership are tools for foreign operators flying foreign-registered drones, not for a U.S. citizen who wants U.S. registration. Dual registration is not allowed, so keeping both numbers on the airframe would not work.

Correct answer: On a durable label fixed to the underside of the aircraft's main body shell

Since the 2019 amendment, 14 CFR 48.205 requires the unique identifier to be legible, securely affixed for the whole flight, and displayed on an external surface of the aircraft, so placing it on a durable label fixed to the underside of the aircraft's main body shell complies. The battery bay that opens by hand was allowed under the original 2015 rule, but an enclosed compartment no longer counts even when no tools are needed. A cover removed with a screwdriver is also inside the aircraft, and the controller is not part of the aircraft that must carry the number.

Correct answer: Four registrations, one per aircraft, for a total fee of $20

A drone flown under Part 107 must be registered whatever it weighs, and 14 CFR 48.100 issues a separate certificate for each aircraft at $5 apiece under 48.30, so the answer is four registrations, one per aircraft, for a total fee of $20. The 0.55 lb exception in 48.15(b) applies only to aircraft flown exclusively under the recreational exception, so the light drone is not exempt here. One registration covering the whole fleet describes the recreational certificate in 48.105, which cannot be used for Part 107 flights.

Correct answer: March 10, 2030

A Part 48 certificate lasts 3 years, so this one expires March 10, 2027; renewal may be done in the six months before the expiration month, and under 48.100(c)(2) the renewed certificate expires three years from the previous expiration date, which is March 10, 2030. November 3, 2029 counts three years from the renewal day, which would penalize early renewal. March 10, 2029 and November 3, 2028 apply a two-year cycle borrowed from the 24-calendar-month recurrent training rule for the remote pilot.

Correct answer: The number on the applicant's remote pilot certificate

The number on the applicant's remote pilot certificate is not part of a Part 48 application, because registration attaches to the aircraft while the remote pilot certificate is a separate Part 107 credential for the person, and an owner need not be a certificated pilot. 14 CFR 48.110 does require the applicant's name, physical address, email and telephone, the manufacturer and model, and, for a standard Remote ID drone, the manufacturer's serial number. That serial number requirement is the tempting one, but it was added with the Part 89 Remote ID rule.

Correct answer: Section 107.36, carrying hazardous material

Section 107.36, carrying hazardous material, is not on the list of waivable regulations in 14 CFR 107.205, so no certificate of waiver can relieve it. Section 107.37(a) on yielding the right of way is the tempting choice because it sounds too basic to waive, yet 107.205(f) lists it. Section 107.35 on multiple aircraft and section 107.145 on flight over moving vehicles are also listed, at 107.205(e) and (j).

Correct answer: The FAA will not waive 107.31 to carry another person's property for compensation

14 CFR 107.205(c) lists the visual line of sight rule as waivable but adds that no waiver of it will be issued to allow carrying the property of another for compensation or hire, so the FAA will not waive 107.31 for this delivery plan. Showing that the flights can be safely conducted is the general waiver standard in 107.200, which is why that option tempts, but the specific exception controls. An over-people waiver does not cure the exception, and visual observers are not a condition that unlocks it.

Correct answer: As a Category 2 operation, meeting all Category 2 requirements in full

When an aircraft is eligible for more than one category, the remote pilot picks one category and meets all of its rules for that operation. Sustained flight over an open-air assembly is allowed only in Category 1, 2 or 4 with Remote ID compliance, so it must fly as a Category 2 operation, meeting all Category 2 requirements in full. Category 3 is barred from open-air assemblies by 107.125(b), whether or not the crowd is told, and mixing the less strict rules of two categories is not allowed.

Correct answer: It no longer qualifies for Category 1, because it is now 0.57 lb with the light

Category 1 requires the aircraft to weigh 0.55 lb or less on takeoff and throughout the flight, including everything on board or attached, so it no longer qualifies for Category 1, because it is now 0.57 lb with the light. Required lighting gets no exemption from that weight, and the limit is not an empty-airframe figure. Staying below 11 ft-lb is only one Category 2 condition; the aircraft also needs an FAA-accepted declaration of compliance and a Category 2 label.

Correct answer: Sustained flight over an open-air crowd inside a fenced, notified venue

Sustained flight over an open-air crowd inside a fenced, notified venue is not permitted, because 107.125(b) bars Category 3 from flying over open-air assemblies even when the venue is closed and everyone has been notified. Inside a closed- or restricted-access site with notice, Category 3 may fly over the people working there. Outside such a site it may pass over pedestrians or moving cars as long as it does not hold sustained flight over them, under 107.125(c)(2) and 107.145(b)(2).

Correct answer: Crossing over the traffic in transit with no sustained flight over cars

Crossing over the traffic in transit with no sustained flight over cars is correct: outside a closed or restricted-access site, 107.145(b)(2) allows Category 1, 2 and 3 aircraft over people in moving vehicles only if they do not maintain sustained flight over the vehicles. Notice to occupants counts only when the vehicles are inside a closed or restricted-access site, so telling one driver on an open road does not help. No height above the vehicles makes sustained flight legal, and the label only shows eligibility for Category 2. It does not lift the moving-vehicle limit.

Correct answer: The latitude and longitude of the takeoff point

The latitude and longitude of the takeoff point is correct: under 89.315 a broadcast module sends the takeoff location and its geometric altitude, while a standard Remote ID drone sends the control station's location under 89.305. Control station location, emergency status and the session ID option belong only to standard Remote ID. A module identifies itself by its own serial number.

Correct answer: A standard Remote ID drone that broadcasts from takeoff to shutdown

A standard Remote ID drone that broadcasts from takeoff to shutdown is correct, because nothing in 89.110 requires the person at the controls to see the aircraft. A broadcast module (89.115(a)) and a FRIA operation (89.115(b)) both require the person manipulating the flight controls to be able to see the drone at all times, so an observer's line of sight does not satisfy them. ADS-B Out cannot be used to meet Remote ID and may not be transmitted under Part 107 without FAA authorization.

Correct answer: Land as soon as practicable and fix the broadcast before the next takeoff

Land as soon as practicable and fix the broadcast before the next takeoff is correct: 89.110(a)(2) requires the person at the controls to land as soon as practicable once the message elements stop broadcasting. The aircraft's self-test is also designed to prevent takeoff while Remote ID is not working. Staying within visual line of sight is a condition of broadcast-module and FRIA operations, not a substitute for a working broadcast, and the 10-day report applies to accidents, not equipment failures.

Correct answer: It cannot satisfy Remote ID, and it may not transmit unless the FAA allows it

It cannot satisfy Remote ID, and it may not transmit unless the FAA allows it, is correct. Section 89.125 says ADS-B Out cannot be used to meet Remote ID, and 107.53 bars operating a small UAS with ADS-B Out in transmit mode unless the FAA authorizes it. The 'extra safety aid' idea is the tempting trap: ADS-B Out is kept off small drones so it does not clutter the manned-aircraft surveillance system.

Correct answer: It must be registered and must meet Remote ID, since the flight is not recreational

It must be registered and must meet Remote ID, since the flight is not recreational, is correct. The under-250-gram exemption from registration applies only to recreational flyers. Every Part 107 aircraft must be registered, and Part 89 applies to every aircraft that is registered or required to be registered. This drone therefore needs a broadcast module, since a FRIA is ruled out, and the module's serial number must be listed on the registration.

Correct answer: An indication of the aircraft's emergency status

An indication of the aircraft's emergency status is a standard Remote ID element (14 CFR 89.305), but it is not on the broadcast module list in 89.315. A module must broadcast the module serial number, the aircraft's latitude, longitude, geometric altitude and velocity, the takeoff location's latitude, longitude and geometric altitude, and a UTC time mark. The takeoff location options are the tempting choice for anyone who remembers only the standard drone list, but the takeoff point is exactly what a module sends in place of the control station location.

Correct answer: The tailgate spot where the drone took off

The tailgate spot where the drone took off is correct because a broadcast module reports the takeoff location's latitude, longitude and geometric altitude (14 CFR 89.315), not the control station. The rooftop spot where the pilot now stands is what a standard Remote ID drone would report, since it broadcasts the control station's position. The module does send a ground location, and the registration address is never part of the broadcast.

Correct answer: Flying it within an FAA-Recognized Identification Area, in sight

Flying it within an FAA-Recognized Identification Area, in sight, is the only Part 89 path left for a drone with no Remote ID equipment and no module (14 CFR 89.115(b)), and the pilot must keep it within visual line of sight. ADS-B Out is not Remote ID, and 14 CFR 107.53 prohibits transmitting ADS-B Out on a Part 107 operation unless the FAA authorizes it. A LAANC authorization is airspace permission only, and the external registration marking is required anyway but does not identify the drone in flight.

Correct answer: Reducing the strobe's intensity while it stays lit and flashing

Reducing the strobe's intensity while it stays lit and flashing is what 107.29 permits: the remote pilot in command may reduce the intensity, but not the lighting itself, when operating conditions make that in the interest of safety. Switching it off removes the required lighting entirely. Switching it to a steady glow removes the flash rate the rule requires, and no waiver is needed for a safety-based reduction in intensity.

Correct answer: Heading toward the crew, roughly nose-on

Heading toward the crew, roughly nose-on, is correct: the red position light is on the airplane's left wingtip and the green on its right, so they appear reversed (red on the observer's right) only when the airplane faces the observer. From behind, the observer would see red on the left, green on the right, and the white tail light. A crossing airplane shows mainly one wingtip color, not both.

Correct answer: From the pilot's right toward the pilot's left

From the pilot's right toward the pilot's left is correct: seeing only the red light means the pilot is looking at the airplane's left side, so its nose points to the pilot's left. From the pilot's left toward the right would require seeing the green right-wing light instead. An airplane coming straight at the pilot would show both red and green, and one moving straight away would show the white tail light.

Correct answer: About 30 minutes

About 30 minutes is correct: dark adaptation of the rods takes roughly 30 minutes, and exposure to bright light destroys it, so the full process starts over. About 5 or 10 minutes describes the much faster adjustment of the cones, which gives only partial night vision. That is why dim or red lighting is recommended during night setup.

Correct answer: A visual observer posted to watch for manned traffic

A visual observer posted to watch for manned traffic is not a 107.29 requirement; a visual observer is optional under Part 107 at night just as it is by day. The rule requires the remote pilot in command to have completed the initial knowledge test or recurrent training after April 6, 2021, and the drone to have anti-collision lighting visible for at least 3 statute miles with a flash rate sufficient to avoid a collision. The training requirement is the item half-prepared candidates most often doubt, but it is written into 107.29(a)(1).

Correct answer: Autokinesis; avoid fixation by shifting the gaze often

Autokinesis; avoid fixation by shifting the gaze often is correct: a single light stared at against a dark background appears to move, and the FAA remedy is to keep the eyes moving rather than fixating. Flicker vertigo is tempting because the light flashes, but it produces disorientation or nausea from flicker at a few cycles per second, not apparent drift of a stationary light. Dark adaptation improves night vision but does nothing to stop autokinesis, and false horizon is a misreading of the horizon from sloping clouds or ground lights.

Correct answer: An advance ATC granted authorization for the Class B airspace

What is required is an advance ATC granted authorization for the Class B airspace, under 14 CFR 107.41, usually issued through LAANC or FAA DroneZone. A Part 107 operational waiver gives relief from an operating rule such as night or over-people limits, and it is not what grants access to controlled airspace. A two-way radio clearance is the manned-aircraft requirement for Class B under Part 91, not the Part 107 one. A Mode C transponder plus ADS-B Out is manned equipment for Class B; Part 107 actually forbids ADS-B Out transmission on small UAS.

Correct answer: 14,500 ft MSL, the Class G roof

Class G reaches 14,500 ft MSL, the Class G roof, above which Class E takes over across the continental United States. 1,200 ft AGL is the Class E shelf that commonly overlies Class G, so it is where Class G usually stops in practice rather than the vertical limit the airspace is defined to have. 18,000 ft MSL is the Class A base, the floor of positive control airspace, and 10,000 ft MSL is a typical Class B peak over a major airport; neither figure bounds Class G.

Correct answer: It requires ATC approval to enter the airspace

The defining trait of Class C is that it requires ATC approval to enter the airspace: manned pilots must establish two-way radio contact, and remote pilots need prior airspace authorization under 107.41, usually through LAANC or DroneZone. Part 107 has no requirement that a NOTAM be filed before any flight. Airport notice before every flight is the old recreational rule for flying within five miles of an airport, not a Part 107 requirement. And a waiver to launch in the airspace is not needed, because an airspace authorization is the approval Class C requires.

Correct answer: Up to 400 ft AGL, the 107.51 airspace limit

A small UAS in Class G must stay up to 400 ft AGL, the 107.51 airspace limit, going higher only within 400 feet of a structure. The 500 ft figure in 91.119 is a minimum safe height for manned aircraft over open areas, not a ceiling for drones. The 1,000 ft figure in 91.119 is the manned minimum over congested areas, again a floor rather than a limit. The 1,200 ft figure in 71.71 marks where Class E commonly begins and Class G ends, which is not the altitude the aircraft may climb to.

Correct answer: To create safe airspace for emergency aircraft

The purpose is to create safe airspace for emergency aircraft. A temporary flight restriction closes a defined volume so that firefighting, law enforcement, disaster relief and similar operations, and the people beneath them, are protected from other traffic. Turbulence and other hazards are passed by AIRMET, SIGMET and PIREP, which advise rather than restrict. A standing volume set aside for military activity is a restricted or military operations area, defined on the chart and not temporary. Park overflight limits come from the land-managing agency rather than from a TFR.

Correct answer: Controlled airspace outside Class A, B, C, or D

Class E is controlled airspace outside Class A, B, C, or D. It is the residual controlled class, beginning at 700 or 1,200 feet AGL in most places and extending up to but not including 18,000 feet MSL. Uncontrolled airspace under the lettered classes is Class G, the opposite of what Class E is. Terminal airspace near towered fields describes Class B, C and D themselves, not the class that fills the gaps between them. Special use airspace is a separate chart overlay, such as a restricted or alert area, and is not an airspace class at all.

Correct answer: Acquire an advance ATC authorization for the Class D airspace

To remain compliant the pilot must acquire an advance ATC authorization for the Class D airspace, as 14 CFR 107.41 requires for Class B, C, D and surface-area Class E, typically through LAANC. Establishing two-way radio contact with the Class D tower is the manned-aircraft rule in Part 91, not the Part 107 requirement. A Part 107 operational waiver relieves an operating rule and does not grant airspace access. Giving the airport operator notice was the old recreational five-mile notification practice and authorizes nothing under Part 107.

Correct answer: Class D needs two-way ATC contact; Class E does not

The difference is that Class D needs two-way ATC contact; Class E does not, because Class D protects an airport with an operating control tower and a pilot must establish communication before entry, while Class E is controlled airspace that VFR traffic may enter without contact. Class D does not reach up to 18,000 feet; it is a small cylinder capped near 2,500 feet AGL, and it is Class E that extends toward FL180. Neither class carries a Mode C equipment requirement of its own, since that belongs to Class B, Class C and the Mode C veil. And a magenta dashed ring marks Class E surface area, not Class D, which is drawn as a dashed blue line.

Correct answer: Class D, which rings the towered airfield

The blue segmented line marks Class D, which rings the towered airfield, since sectionals draw Class D as a dashed blue outline around an airport with an operating control tower. Class B over the busiest gateway is drawn as a solid blue line rather than a dashed one. Class C over the midsized airport is drawn in solid magenta. And Class E is never a dashed blue ring, because its surface area is a dashed magenta line and its 700-foot floor is a shaded magenta band.

Correct answer: 10,000 ft MSL

Class B is normally capped at 10,000 ft MSL. The inverted wedding-cake structure around the nation's busiest airports typically runs from the surface up to 10,000 feet MSL, with a Mode C veil out to 30 nautical miles. 14,000 ft MSL corresponds to no airspace boundary. 18,000 ft MSL is the floor of Class A, well above any Class B shelf, and 24,000 ft MSL is simply a cruising level inside Class A.

Correct answer: Charlie

Charlie is the ICAO phonetic word for the letter C, the fixed word used on aviation radio so a letter survives a noisy channel. Charles is the C word in the APCO police radio alphabet, not the aviation one. Cecilie is the C word in the Danish national spelling alphabet. Coca was the C word in the 1949 to 1951 ICAO draft alphabet that was replaced before the current one took effect.

Correct answer: Niner

In aviation radiotelephony the digit 9 is spoken as Niner, so it is not mistaken for the German nein or lost on a weak channel. Fower is the real ICAO pronunciation of the digit 4, not 9. Fiver is a common misremembering by analogy with niner; the ICAO form of 5 is Fife. Plain Nine is exactly the pronunciation the phraseology replaces, because it is too easily confused or clipped.

Correct answer: Hold your spot and wait for further word

Stand by means hold your spot and wait for further word: the controller heard you and will call back when ready. It is not an approval, so waiting a moment and then proceeding as requested acts on a clearance never given. Waiting a moment and then repeating your request clutters the frequency when the controller has already promised the callback. And it is not a denial, so reading it as request denied, hold off and call again, mistakes a pause for a refusal.

Correct answer: To end the mix-ups among like letters and digits

The phonetic alphabet exists to end the mix-ups among like letters and digits, because B, D, E and P sound almost identical through a weak radio while Bravo, Delta, Echo and Papa do not. To hasten the delivery and flow of each exchange gets it backward, since spelling a word out takes longer than saying it; to lend the radio a crisp and professional voice names a side effect rather than the reason; and to trim the size and length of each transmission is brevity, which the alphabet spends rather than saves.

Correct answer: Will comply

Wilco is the standard contraction for will comply, meaning the message was received, understood and will be carried out. Will copy confuses it with roger, which only confirms receipt without promising action. Will concur and will convey match the letters but are not the phrase's meaning; concurring is agreeing with an opinion and conveying is relaying a message, neither of which commits the pilot to follow the instruction.

Correct answer: Roger

Roger is the standard phraseology meaning the last transmission was received, which is exactly what acknowledging and confirming receipt of a message calls for. Wilco means the pilot will comply with an instruction, so it adds a commitment to act and is used in reply to instructions rather than as a plain acknowledgment. Break separates portions of a transmission. Out ends the conversation with no reply expected, rather than confirming receipt.

Correct answer: Separates the message into two clear parts

The word separates the message into two clear parts, so one transmission can carry two distinct pieces of traffic without them running together. Signals the outright finish of the message describes Out, the end-of-transmission word; demands a lengthy pause inside the message overstates it, since what is marked is a boundary rather than a wait; and instructs the station to cease its message would be an order to stop transmitting, which is not what the word conveys.

Correct answer: It means a strong no

Negative is the standard radiotelephony word for no, so it means a strong no: permission not granted, or that is not correct. It means cannot copy confuses it with Say again or an unreadable transmission. It means cannot spot belongs to the longer phrase Negative contact, used when reported traffic is not in sight. It means cancel that describes Disregard, which voids the last transmission.

Correct answer: To close a call and invite a prompt answer

Over is spoken to close a call and invite a prompt answer: the speaker has finished and is handing the channel back for an answer. To flag a problem and yell for urgent help belongs to a distress or urgency call rather than to routine turn-taking; to signal the finish and outcome of a task reads the word as a mission report; and to confirm a message as heard and taken in is the work of Roger, which acknowledges instead of inviting a response.

Correct answer: Automatic Terminal Information Service

ATIS is the Automatic Terminal Information Service, the recorded broadcast of weather, runway and field information repeated continuously at busier airports. The other three expansions are invented: no aviation instruction standard, airborne identification signal or aerodrome schedule stands behind those four letters.

Correct answer: To show wind direction and the active traffic pattern

A segmented circle is there to show wind direction and the active traffic pattern to pilots arriving at a field without a tower. Ground vehicles are steered by painted markings rather than by the circle, restricted airspace is charted rather than laid out on the ground, and the tower and its frequency are published in the chart supplement.

Correct answer: The airport is open for night operations also

An alternating white and green beacon marks a lighted civil land airport, so the airport is open for night operations also. It is not reserved for military flights, because a military field flashes two quick whites between each green. It is not closed to arriving traffic today, because a closure is marked by a painted or lighted X on the runway rather than by the beacon. And the beacon says nothing about whether the airport is served by a control tower, which the chart and frequency listing show instead.

Correct answer: The wind direction and speed with current sky cover

A METAR is a routine observation of current conditions at the airport, so it reports the wind direction and speed with current sky cover, plus visibility, weather, temperature, dew point and altimeter setting. Forecast winds aloft with temperatures by level come from the winds and temperatures aloft forecast (FB). Forecast ceiling and visibility across 24 hours is a TAF, a forecast rather than an observation. Turbulence and icing reported by pilots aloft arrive as PIREPs, not in a METAR.

Correct answer: They mark the taxiways and the other non-runway areas

Correct answer: They mark the taxiways and the other non-runway areas. Yellow is the color of the movement-area scheme, identifying the surfaces a pilot or vehicle uses to get to and from the runway. They mark the runway edges and the centerline stripes belongs to the white runway scheme instead. They mark the secure gates and the no-entry barricades describes access control, which is conveyed by signs and physical barriers rather than by the pavement color code. They mark the rescue lanes and the fire-truck routes is not what the yellow code means either.

Correct answer: Obtain an ATC authorization for controlled airspace near the airport

Part 107 ties airport operations to airspace class, not distance, so the pilot must obtain an ATC authorization for controlled airspace near the airport under 107.41, usually through LAANC or DroneZone. Obtaining ATC authorization for any flight within 5 miles is wrong because an airport in Class G airspace needs none. Notifying the airport operator and the tower when flying near the field is the old recreational notice and grants no access. The airport operator's waiver does not exist; only the FAA issues waivers, and airspace entry needs an authorization.

Correct answer: To guide the airport pilots through takeoff, landing and taxi

Airport lighting exists to guide the airport pilots through takeoff, landing and taxi: runway edge, threshold, approach, glide slope and taxiway lights all do that job. Signalling traffic with ATC clearances is the job of the tower's light gun, which is separate from the airfield lighting system. Airspace limits around an airport are shown on sectional charts, not by lights on the ground. Noise-abatement routes are published procedures, and no lighting system marks them.

Correct answer: A spot on the airport where vehicles and aircraft conflict

A hot spot is a spot on the airport where vehicles and aircraft conflict, charted on the airport diagram so crews slow down and look before crossing. A marked pad on the ramp used for launches and landings is simply a movement area rather than a collision risk point. A busy terminal hall of shops and counters lies outside the movement area altogether. And a fenced plot held for crews and rescuers is a staging area for emergency equipment.

Correct answer: A notice of short term changes in airspace or field conditions

A NOTAM is a notice of short term changes in airspace or field conditions, such as a runway closure, a crane or a temporary flight restriction, so remote pilots near airports must check them. A broadcast of current weather and active runway at an airport is ATIS. An advisory of hazardous weather such as icing or low ceilings is an AIRMET or SIGMET. A report from pilots of turbulence or icing seen along a route is a PIREP. None of those announces temporary airspace changes.

Correct answer: The wind direction and its rough relative strength

A wind sock shows the wind direction and its rough relative strength at the surface, since it swings downwind and fills out as the wind builds. It samples surface air only, so it gives neither the winds aloft direction and speed at the pattern nor the wind shear and turbulence over the pattern, and it is not a landing pattern direction the tower has set, which a wind tee or tetrahedron can display.

Correct answer: Class G airspace, the low-altitude surface layer

Class G airspace, the low-altitude surface layer, is the only uncontrolled class, so it requires neither ATC communication nor an authorization for a small UAS. Class E airspace, the 700-foot AGL transit layer does not require manned VFR pilots to talk to ATC, but it is still controlled airspace. Class E airspace, the 1,200-foot federal airways is controlled as well, carrying the Victor airway structure. Class D airspace, the 2,500-foot AGL tower layer is controlled and requires two-way radio communication with the tower for manned aircraft.

Correct answer: Advance authorization from the controlling agency

Correct answer: Advance authorization from the controlling agency. A restricted area exists because an activity hazardous to aircraft takes place inside it, and entry is permitted only with the prior approval of the agency that uses and controls the area, which is usually a military command. LAANC authorization from a participating supplier covers controlled airspace around airports and has no bearing on restricted areas, which are outside that system entirely. Standing authorization from the operating airport fails because an airport and its control tower do not own a restricted area and cannot grant entry to it. Recurring authorization from the nearest district misplaces the decision with an FAA field office, which administers certificates and waivers rather than access to another agency's airspace.

Correct answer: Military Operations Areas, charted as MOA zones

The answer is Military Operations Areas, charted as MOA zones: an MOA separates military training from IFR traffic, and a small UAS needs no ATC authorization to operate inside one, though checking activity times is wise. Restricted Areas used for gunnery and firing operations require permission from the using or controlling agency before entry. Controlled Firing Areas are not charted at all, and their activity is suspended when aircraft approach rather than being designated military airspace. Prohibited Areas over military or federal land bar flight entirely for security reasons.

Correct answer: To manage the flow around the busiest airports

Correct answer: To manage the flow around the busiest airports. Class B is drawn around the nation's highest-volume airports and exists to sequence and separate the heavy mix of arrivals and departures there, which is why every aircraft inside it operates under an explicit clearance. To protect the ranges from the nearby aircraft describes special use airspace such as restricted areas, which is drawn for hazardous activity rather than for traffic volume. To divide the arrivals from the visual flights states a service that controllers provide in several classes of airspace and is not the reason Class B exists. To separate the traffic above the high airways describes Class A, the airspace that begins at 18,000 feet MSL and requires instrument flight rules.

Correct answer: Class E airspace, which covers the enroute structure

Correct answer: Class E airspace, which covers the enroute structure. The published low-altitude Victor airways are Class E controlled airspace, which fills the space between terminal areas and the high-altitude system and gives instrument traffic a protected route structure between airports. Class A airspace, which covers the highest altitudes, begins at 18,000 feet MSL and contains the jet route system rather than the low-altitude airways. Class B airspace, which covers the busiest terminals, is drawn around individual major airports and is terminal airspace, not a route structure spanning the country. Class G airspace, which covers the lowest boundaries, is uncontrolled, and an uncontrolled volume cannot host a protected federal airway.

Correct answer: It restricts flights near the national security sites

Correct answer: It restricts flights near the national security sites. A Flight Restricted Zone is drawn to shield locations of national security significance, the Washington DC zone around the Capitol and the White House being the best known, and small unmanned aircraft are effectively barred from it. It restricts flights near the seasonal disaster areas describes a temporary flight restriction issued for wildfires, floods, and similar hazards, which is a different instrument with a defined expiry. It restricts flights near the military exercise lanes describes special use airspace such as military operations areas and restricted areas, which exist for training rather than for security of a fixed site. It restricts flights near the crowded stadium grounds describes the standing sporting-event restriction, which is tied to a game in progress rather than to a permanently protected location.

Correct answer: To confine selected aviation activities and limit traffic conflicts

Special use airspace exists to confine selected aviation activities and limit traffic conflicts: restricted areas, MOAs, warning, alert and prohibited areas each bound an activity so other traffic can plan around it. Protecting temporary events and VIP movements is the job of a temporary flight restriction, which is not special use airspace. Protecting busy airports' instrument approaches is the purpose of Class B terminal airspace. Protecting sensitive ground facilities from low overflying aircraft describes a National Security Area, which is charted as other airspace, not special use airspace.

Correct answer: By checking the sectional chart lateral boundaries

Correct answer: By checking the sectional chart lateral boundaries. A sectional chart draws Class C as magenta rings with the lateral limits and the floor and ceiling of each shelf printed on it, so the chart is what tells the remote pilot whether a planned position lies inside the airspace. By reading the published NOTAM advisory statements will not answer the question, because notices report temporary changes and closures rather than the fixed shape of an airspace class. By observing the overhead manned traffic movements is unreliable, since aircraft transit the area whether or not the operator is inside the ring, and the boundary is invisible from the ground. By confirming the cruising altitude below ceilings confuses two separate rules: staying under the altitude limit does not exempt an operation from the authorization required inside controlled airspace.

Correct answer: To seek permission for entry into the controlled airspace

Under 14 CFR 107.41 a small unmanned aircraft may not operate in Class B, C, D or surface Class E airspace without ATC authorization, so the purpose is to seek permission for entry into the controlled airspace, usually through LAANC or DroneZone. Class G airspace needs no ATC clearance at all. A waiver for flights over people is issued by the FAA waiver office under 107.205, not by a controller. Part 107 operations do not require an ATC-approved NOTAM, and controllers do not approve them.

Correct answer: The approach rides exactly along the published glide path

Correct answer: The approach rides exactly along the published glide path. Explanation: A four-light PAPI shows an even split when the aircraft is on the correct vertical path: two white on the side away from the runway and two red nearer it. Three or four white lights mean the aircraft is high, so a reading of two and two cannot indicate a position above the path. Three or four red lights mean the aircraft is low, so two and two cannot indicate a position below it either. PAPI resolves the vertical dimension only and says nothing about lateral position, so no combination of its lights reports a drift left or right of centerline.

Correct answer: Class C airspace from the ground surface to 4,100 ft MSL; advance ATC authorization required

Correct answer: Class C airspace from the ground surface to 4,100 ft MSL; advance ATC authorization required. Explanation: A solid magenta circle around an airport depicts Class C airspace, and a segmented box reading 41/SFC gives a ceiling of 4,100 ft MSL over a floor at the surface. Part 107 operations there need prior ATC authorization under 14 CFR 107.41, normally issued through LAANC. Class D is drawn with a dashed blue line, and a broadcast on CTAF is a courtesy that authorizes nothing. Class B is drawn with solid blue lines, and a DroneZone waiver covers rule deviations rather than airspace entry. Class E starting overhead would be drawn as a vignette or dashed magenta line, and reading a NOTAM grants no entry.

Correct answer: Class D airspace; preflight ATC authorization is mandatory before each planned takeoff

A dashed blue circle depicts Class D airspace; preflight ATC authorization is mandatory before each planned takeoff under 14 CFR 107.41, normally obtained through LAANC. Class E reaching the surface is drawn in dashed magenta rather than dashed blue, so the class named there is wrong even though authorization would also be required. Class C is drawn as a solid magenta circle, and the two-way radio contact rule applies to manned aircraft rather than to a small unmanned aircraft. Class G is shown by the absence of any boundary, and a DroneZone waiver deviates from an operating rule instead of opening controlled airspace.

Correct answer: Class E airspace dropping well down onto the field surface, guarding IFR approaches

A dashed magenta line encircling an airport depicts Class E airspace dropping well down onto the field surface, guarding IFR approaches, since that airspace is designated to begin at the ground so instrument arrivals and departures stay inside controlled airspace. Class D is drawn with a dashed blue line rather than a magenta one, whatever clearance it demands. Class B is drawn in solid blue and its shelves sit over a major terminal area, not around a small field. Class G is uncontrolled and is shown by the absence of a boundary, and an alert area carries its own magenta hatched border with a lettered name.

Correct answer: The box indicates a 4,100 ft MSL ceiling above a 1,200 ft floor

Correct answer: The box indicates a 4,100 ft MSL ceiling above a 1,200 ft floor. Explanation: Numbers in a segmented airspace box are hundreds of feet MSL, top over bottom, so 41/12 gives a shelf ceiling of 4,100 ft MSL over a shelf floor of 1,200 ft MSL, and the air below 1,200 ft MSL there is not Class C. Reading 41,000 over 12,000 inflates the tier tenfold and would push the shelf into the flight levels. The numbers are altitudes rather than distances, so they never express an outer radius or an inner ring in nautical miles. And the shelf does not descend to the airport ground, because the lower figure is a charted floor quoted MSL rather than AGL.

Correct answer: 700 ft AGL, the standard Class E transition base near fields

Correct answer: 700 ft AGL, the standard Class E transition base near fields. Explanation: A faded magenta vignette marks a Class E transition area whose floor sits 700 ft above the ground, lowered from the usual base so that instrument traffic is inside controlled airspace on approach. The faded blue vignette is the symbol for a 1,200 ft AGL Class E floor, which is the wider en route case rather than the magenta one. 400 ft AGL is the Part 107 operating ceiling from 14 CFR 107.51 and describes where the aircraft may fly, not where controlled airspace begins. 500 ft AGL is the manned-aircraft minimum safe altitude over open country under 14 CFR 91.119 and has nothing to do with the vignette.

Correct answer: Class G uncontrolled airspace; the ATC authorization stays entirely unnecessary

Correct answer: Class G uncontrolled airspace; the ATC authorization stays entirely unnecessary. Explanation: Sectionals show Class G by the absence of a symbol: no solid or dashed boundary and no vignette shading near the ground means the airspace below the overlying controlled airspace is uncontrolled, and 14 CFR 107.41 requires authorization only in Class B, C, D and surface Class E. Class D would be drawn with a dashed blue line and would require authorization. A Class E transition area would show a faded magenta or blue vignette, and LAANC issues authorization rather than removing the need for it. Class B would be drawn with solid blue lines, and a DroneZone waiver covers rule deviations, not airspace entry.

Correct answer: Class B airspace; the pilot first obtains prior ATC authorization locally

A solid blue line depicts Class B airspace, so the answer is Class B airspace; the pilot first obtains prior ATC authorization locally, normally through LAANC or DroneZone under 14 CFR 107.41. Class D is drawn with a dashed blue line, not a solid one, so reading the ring as Class D confuses the line style. Class C is drawn in solid magenta, so the colour rules it out. A Class E surface area is a dashed magenta line, so the depiction does not match that class either.

Correct answer: No, because 800 ft MSL remains underneath the 1,300 ft MSL shelf floor

Correct answer: No, because 800 ft MSL remains underneath the 1,300 ft MSL shelf floor. Explanation: The outer ring box reading 41/13 puts the shelf floor at 1,300 ft MSL, so the Class C airspace in that ring does not begin until 1,300 ft MSL. A flight at 200 ft AGL over terrain of about 600 ft MSL reaches roughly 800 ft MSL, which is beneath the shelf and therefore in uncontrolled airspace where no ATC authorization is needed. Telling the airport operator is courteous but is not the reason authorization is unnecessary. The airspace beneath a shelf is not itself Class C, which is why the floor altitude is charted at all. Class C has no blanket 5 NM proximity rule for small unmanned aircraft.

Correct answer: 400 ft AGL, or 400 ft above a structure positioned within 400 ft

14 CFR 107.51(b) sets the limit at 400 ft AGL, or 400 ft above a structure positioned within 400 ft, measured from the structure's immediate uppermost limit. The structure allowance needs no LAANC approval, so the LAANC option attaches a condition the rule does not impose. The ATC clearance option is wrong for the same reason; clearances govern manned traffic and the allowance works without one. 400 ft above the launch point, as the app's height readout shows confuses height above takeoff with height above the ground directly below the aircraft.

Correct answer: Near real-time authorization for controlled airspace up to published UAS Map ceilings

Correct answer: Near real-time authorization for controlled airspace up to published UAS Map ceilings. Explanation: LAANC, the Low Altitude Authorization and Notification Capability, checks a requested operation against the UAS Facility Map grid for the airport and returns an authorization within seconds, valid up to the ceiling published for that grid square. It authorizes airspace entry only; every other Part 107 operating rule still applies, so it is not a blanket waiver. It does not raise the 400 ft AGL limit, and nowhere does it grant nationwide permission to climb higher. Further coordination requests handled manually by the facility are the slow path LAANC exists to replace, not what LAANC itself provides.

Correct answer: The pilot keeps clear of the TFR lateral plus vertical limits unless permitted

The pilot keeps clear of the TFR lateral plus vertical limits unless permitted, meaning a specific FAA authorization; a stadium restriction covers three nautical miles up to 3,000 ft AGL from one hour before to one hour after the event. LAANC grants controlled-airspace access and cannot authorize entry into a TFR. Staying out only from kick-off to the final whistle ignores the hour on either side that the restriction also covers. The stadium operator's consent is not an FAA authorization and gives no relief from the restriction.

Correct answer: Temporary hazards such as a TFR, blocked runways, or unlighted obstructions

Correct answer: Temporary hazards such as a TFR, blocked runways, or unlighted obstructions. Explanation: Notices to Air Missions carry the time-critical, temporary information a chart cannot show: flight restrictions, airspace changes, closed or shifted runways, unlit towers and cranes, and outages of navigation aids in the operating area. Density altitude is a performance figure the pilot computes from temperature, altimeter setting and elevation, and no notice publishes it. Winds, ceilings and convective outlooks come from weather products such as the TAF and the convective advisory, which are issued separately from notices. Aircraft registration is a matter of the FAA registry and has nothing to do with preflight hazard awareness.

Correct answer: The CTAF frequency; the pilot monitors it for adjacent manned arrival traffic

Correct answer: The CTAF frequency; the pilot monitors it for adjacent manned arrival traffic. Explanation: At a non-towered field, manned pilots self-announce position and intentions on the common traffic advisory frequency, so a remote pilot who listens to it knows where the traffic is and can yield right of way as 14 CFR 107.37 requires. UNICOM is an air-to-ground service run by a fixed base operator and issues no departure advisories a remote pilot could act on. The center frequency handles en route traffic and issues no clearances to a small unmanned aircraft. The automatic terminal information service is a recorded broadcast, so nothing a remote pilot transmits on it would be heard.

Correct answer: A hazardous FAA area needing the controlling agency's approval when active

Correct answer: A hazardous FAA area needing the controlling agency's approval when active. Explanation: A restricted area such as R-2503 confines activity hazardous to nonparticipating aircraft, artillery fire, guided missiles or aerial gunnery, and while it is active the pilot needs clearance from the controlling or using agency before entering. It is not a practice area drawing student traffic, since entry there is limited rather than encouraged. It is not permanently sealed either, because the chart panel publishes the altitudes and times when the restriction applies and the airspace is released outside them. And a band of military activity that nonparticipating pilots may cross at their own discretion is a military operations area, a different designation entirely.

Correct answer: The Class B ceiling reaches 10,000 ft MSL over a 3,000 ft floor

Correct answer: The Class B ceiling reaches 10,000 ft MSL over a 3,000 ft floor. Explanation: Numbers in an airspace box are hundreds of feet MSL with the ceiling written over the floor, so 100/30 means a tier that tops out at 10,000 ft MSL and whose base is 3,000 ft MSL at that location. The figures are altitudes, so neither one expresses a radius in nautical miles from the primary airport. Reading them as 1,000 and 300 drops a factor of ten and would place an airline terminal area a few hundred feet off the ground. Class B is layered like an inverted wedding cake, so only the innermost tier reaches the surface and this outer tier plainly does not.

Correct answer: Yes, because Class E surface airspace counts as controlled airspace requiring authorization

Correct answer: Yes, because Class E surface airspace counts as controlled airspace requiring authorization. Explanation: Class E designated to the surface, drawn with a dashed magenta line, is controlled airspace, and 14 CFR 107.41 requires prior ATC authorization for any Part 107 operation inside it. The weather figures of a 1,000 ft ceiling and three statute miles are the basic VFR minimums for manned aircraft and do not decide whether authorization is needed. Class E is not uniformly uncontrolled; the portions that reach the surface are exactly the controlled ones. The lack of a control tower changes nothing, because the authorization is issued by the facility that controls the airspace, tower or not.

Correct answer: Class G up to 700 ft AGL, so no ATC authorization is needed

Class G up to 700 ft AGL, so no ATC authorization is needed: the shaded side of a magenta vignette marks Class E whose floor is 700 ft above the ground, so a drone at 380 ft AGL is still in Class G. The tempting trap is reading the 700 as MSL; with the field at 650 ft MSL the drone is near 1,030 ft MSL, but the floor is measured from the ground, and even non-surface Class E would need no authorization under 107.41. Class E from the surface is shown by a dashed magenta line, which the site is outside of, and the 1,200 ft floor belongs to the unshaded side of the vignette.

Correct answer: 350 ft AGL, the 1,500 ft MSL floor less the terrain

The answer is 350 ft AGL, the 1,500 ft MSL floor less the terrain: Class C box figures are hundreds of feet MSL, so 15 means a floor of 1,500 ft MSL, and 1,500 minus 1,150 leaves only 350 ft of Class G or Class E below the shelf. Taking the lower box figure as a height above the ground ignores that the figures are MSL, and 1,200 ft AGL is the typical design height of a shelf, not what this box says. 2,850 ft AGL comes from subtracting the terrain from the upper MSL figure, which is the ceiling, not the floor. A drone here must stay below 350 ft AGL, not 400, unless it holds an ATC authorization.

Correct answer: The Class D top stops short of 2,500 ft MSL, where the Class B begins

The minus sign means the Class D top stops short of 2,500 ft MSL, where the Class B begins: the Chart User's Guide defines a minus ceiling value as surface up to but not including that altitude, usually because overlying airspace begins there. Without the minus, [25] would mean the Class D top includes 2,500 ft MSL. Class D ceilings are always charted in MSL, never AGL, and part-time status is shown by a star and the Chart Supplement, not by a minus sign.

Correct answer: ATC authorization is still required, as a surface area stays controlled at night

ATC authorization is still required, as a surface area stays controlled at night: 107.41 names the surface area of Class E designated for an airport alongside Classes B, C and D, so the closed tower changes the class but not the need for authorization, which LAANC or FAADroneZone can still issue. The tempting belief that a surface area needs no authorization once the tower closes confuses it with non-surface Class E, such as the 700 or 1,200 ft AGL floors, which needs none. The absence of a controller does not remove the requirement, and a CTAF call is good practice but never a substitute for authorization.

Correct answer: Neither a waiver nor ATC authorization, as this Class E is no surface area

The answer is neither a waiver nor ATC authorization, as this Class E is no surface area. Under 107.51(b) a drone may exceed 400 ft AGL within a 400 ft radius of a structure and up to 400 ft above its top, here 1,450 ft AGL, and 107.41 requires authorization only in Classes B, C, D and Class E surface areas. The tempting choice treats climbing into the Class E that begins at 1,200 ft AGL as needing authorization, but non-surface Class E needs none; a waiver is unnecessary because the structure allowance already covers the climb.

Correct answer: Below a Class B tier whose box reads 70/15

The site below a Class B tier whose box reads 70/15 needs no authorization: its floor is 1,500 ft MSL, and the drone at 200 ft AGL is only at 1,250 ft MSL, so it stays beneath the Class B. The tempting Class C shelf reading 40/12 has a floor of 1,200 ft MSL, just 150 ft above this terrain, so the drone at 1,250 ft MSL is inside Class C. The Class B core starting at SFC and the Class D ring both begin at the surface, so any flight there needs authorization.

Correct answer: Class G, as Class E begins at 1,200 ft AGL away from the vignette

The drone is in Class G, as Class E begins at 1,200 ft AGL away from the vignette: the 700 ft AGL floor applies only on the shaded side of a magenta vignette, and outside it, absent other depiction, Class E begins at 1,200 ft AGL. Choosing the 700 ft floor reads the vignette backwards. Measuring 1,200 from sea level would wrongly put the drone, at 1,350 ft MSL, in Class E. The 107.51(b) structure allowance raises the altitude limit but never makes the airspace beside a tower Class G.

Correct answer: 1,449 ft AGL, which is 400 ft above the tower top

The highest is 1,449 ft AGL, which is 400 ft above the tower top: an obstruction symbol shows MSL height on top and AGL height in parentheses, and 107.51(b) allows up to 400 ft above the structure's uppermost limit within a 400 ft radius. The 1049 in parentheses is the tower top AGL, so 1,449 ft AGL is the limit. Adding 400 to the top figure (1749, an MSL value) and calling it AGL overstates the limit by the terrain height, and stopping at the figure in parentheses ignores the allowance that lets the drone go 400 ft above the top.

Correct answer: Flying under an unmanned free balloon is fine if the drone keeps 500 ft below

The unsound assumption is that flying under an unmanned free balloon is fine if the drone keeps 500 ft below: the AIM says flight below these balloons should be avoided at all times, because a payload, suspension device or trailing antenna can hang far below the envelope. The 500 ft figure borrows the cloud-clearance rule and does not apply. Guy wires can reach about 1,500 ft from a tower, thermal plumes bring turbulence and reduced visibility, and steel structures disturb a magnetic compass, so those assumptions are all sound.

Correct answer: 2,549 ft MSL

The bold figure is the top of the tower in MSL, and 14 CFR 107.51(b) allows flight up to 400 ft above the structure's immediate uppermost limit when within 400 ft of it, so 2,149 + 400 = 2,549 ft MSL. 1,449 ft is the right number in AGL (1,049 + 400) mislabeled as MSL, and 1,500 ft MSL is just the ordinary 400 ft AGL limit over 1,100 ft ground. 2,149 ft MSL wrongly caps the flight at the tower's top, when the rule allows 400 ft above it.

Correct answer: No ATC authorization, as non-surface Class E needs none

No ATC authorization, as non-surface Class E needs none: 14 CFR 107.41 requires prior authorization only for Class B, C, D and the surface area of Class E designated for an airport, and 107.51(b) permits 1,450 ft AGL here because it is within 400 ft of a 1,100 ft tower and under 1,500 ft AGL. The LAANC and DroneZone answers both treat all controlled airspace as needing authorization, but Class E that begins at 700 ft AGL is not on the 107.41 list. No altitude waiver is needed because the structure exception in 107.51(b) already allows the climb.

Correct answer: 1,150 ft AGL and 350 ft laterally from the tower

1,150 ft AGL and 350 ft laterally from the tower complies, because 107.51(b) allows up to 400 ft above the top (here 1,200 ft AGL) only within a 400 ft radius. 1,250 ft AGL is inside the radius but 50 ft above the 1,200 ft limit. At 500 ft and 450 ft laterally the aircraft is outside the 400 ft radius, so the normal 400 ft AGL ceiling applies and both 950 and 600 ft AGL are too high.

Correct answer: About 1,500 ft from the structure

The AIM states that guy wires supporting skeletal structures can extend about 1,500 ft horizontally from the structure, which is why the AIM recommends avoiding skeletal structures horizontally by at least 2,000 ft. That 2,000 ft figure is the avoidance distance, not the wire reach. 1,000 ft is the AIM's height threshold for tall towers, and 400 ft is the Part 107 lateral radius for the structure exception, neither of which describes how far guy wires reach.

Correct answer: Every power line under 200 ft AGL is charted as an obstruction on a sectional

The statement that every power line under 200 ft AGL is charted is wrong: the AIM warns that at and below 200 ft AGL there are numerous power lines and towers that are not marked, lighted or charted, so they can be invisible at night. The middle, top, bottom white strobe sequence on line support structures is real and signals wires between them. Spherical markers on wires may be lighted, and NOTAMs are issued for lighted structures with temporary light outages.

Correct answer: Stay on the west side of the tower, upwind, so the plume drifts away

The AIM tells pilots to steer clear of exhaust plumes by flying on the upwind side of smokestacks or cooling towers, which with a west wind is the west side. The downwind side is where the plume drifts, carrying turbulence, reduced visibility and corrosive gases, even if it keeps the plume in view. Using the structure allowance to fly over the top puts the aircraft in the plume, whose turbulence can reach over 1,000 ft above the stack.

Correct answer: A taller stack is a reliable sign that the plume turbulence is stronger

The AIM says the size of the tower or stack is not a good indicator of the plume's effect; the major factors are the heat or size of the effluent, the ambient temperature and the wind speed. It also says significant turbulence can extend over 1,000 ft above the stack top, that effects are most pronounced in calm, stable, cold air, and that a stack without a visible plume may still be in full operation.

Correct answer: Move it sideways out of its own downwash, then descend at an angle

This is vortex ring state, or settling with power: the rotors descend into their own downwash, so adding power in place only strengthens the recirculating vortex. The recovery is to move the aircraft laterally into clean air and then descend more slowly at an angle. Climbing straight up with full power is the instinctive response but keeps the rotors in the disturbed air, and hovering or yawing in place does not leave the downwash.

Correct answer: Charge built up as the airframe hit airborne dust or other particles

The AIM explains that P-static builds up when an aircraft strikes airborne particles such as rain, snow, fog, sleet, hail, volcanic ash or dust, leaving a negative charge on the airframe, and lists symptoms including radio noise, loss of communications and erratic compass readings. Power-line fields cause electromagnetic interference, not P-static. Dry air alone without particles does not produce it, and a distant lightning strike is a separate phenomenon.

Correct answer: 2,149 ft MSL

The bold figure is the tower top in MSL and the parenthetical figure is its height AGL, so the ground sits at 600 ft MSL. Under 14 CFR 107.51(b), within a 400 ft radius of a structure the aircraft may fly up to 400 ft above the structure's uppermost limit: 1,149 + 400 = 1,549 ft AGL, which is 2,149 ft MSL. The tempting 1,549 ft MSL adds the 400 ft to the AGL height correctly but then labels an AGL result as MSL, which would put the aircraft below the top of the tower.

Correct answer: Inside the guy-wire zone, which can reach about 1,500 ft out

The AIM warns that guy wires are very hard to see and can extend about 1,500 ft horizontally from a structure, so a line 1,200 ft from the base is inside the area the wires can occupy. The 2,000 ft figure is the AIM's recommended horizontal avoidance distance for skeletal structures, not how far the wires reach. The 400 ft figure comes from the Part 107 structure-altitude rule and has nothing to do with wire extent.

Correct answer: Cross a cooling tower's plume, since its vapor poses little real risk

Crossing the cooling tower's plume is the point that breaks FAA guidance. The AIM says to avoid exhaust plumes from smoke stacks and cooling towers because they can cause turbulence, vertical shear, reduced visibility and icing, and an invisible plume can still be present. Holding upwind of a fire is correct because the smoke drifts downwind. Avoiding flight beneath a free balloon is correct because its payload or trailing antenna hangs below it, and calibrating away from steel avoids magnetic interference.

Correct answer: Mist

BR reports mist. The contraction comes from the French brume, and it is coded when suspended water droplets cut prevailing visibility to between 5/8 and 6 statute miles with the air near saturation. Haze is coded HZ and is dry particulate rather than water droplets, and it does not require near-saturated air. Dust is coded DU and is lifted soil, again not condensed moisture. Hail is coded GR, or GS for small hail and snow pellets, and is precipitation reported as a convective hazard rather than an obscuration.

Correct answer: Broken clouds at 800 ft AGL

BKN008 means broken clouds at 800 ft AGL: BKN is five to seven eighths of sky cover, and the three digits give the cloud base in hundreds of feet above ground level. METAR cloud heights are never reported in MSL, so an 800 ft MSL reading is wrong. Reading 008 as 8,000 ft treats the digits as thousands instead of hundreds, whether labelled AGL or MSL.

Correct answer: SPECI

SPECI is the one issued for a temporary or rapidly changing condition. A SPECI is an unscheduled special observation put out between the routine hourly cycle whenever a criterion such as a visibility, ceiling, wind shift or thunderstorm change is met. TREND is a forecast group appended to an observation in some countries, not a report of what is happening now. METAR is the scheduled routine observation and is issued on the clock whether or not anything has changed. NOTAM carries airspace and facility notices and reports no weather at all.

Correct answer: The altitude corrected for a nonstandard air temperature

Density altitude is the altitude corrected for a nonstandard air temperature: formally, pressure altitude corrected for temperature away from the standard 15 degrees Celsius, so it tells the pilot what altitude the air feels like to a wing or a propeller. The altitude above the average ocean surface is true altitude, or MSL height. The altitude adjusted for the barometric setting is indicated altitude, which the altimeter shows once the local setting is dialed in. The altitude taken from the standard atmosphere tables is pressure altitude, which is only the starting point for the temperature correction.

Correct answer: METAR

METAR gives the fullest picture of conditions at the surface right now, encoding wind, visibility, present weather, sky cover at each layer, temperature, dew point and altimeter setting for one station at one time. AIREP is a single pilot's account of what was met aloft, subjective and tied to one point in space and time. SIGMET is an advisory warning of one significant hazard rather than a full observation of current conditions. TAF is a forecast of what a terminal is expected to see later, not a report of what it has now.

Correct answer: Every clock hour

A METAR is issued every clock hour, normally in the ten minutes before the hour, so a station produces twenty-four routine observations a day. Every third hour, every fifth hour and every sixth hour would each leave long stretches with no current surface report, which is the opposite of what a routine observation is for; six-hourly issue describes the synoptic observations used for large-scale analysis, not the aviation METAR cycle. Conditions that change between the hourly reports are covered by a SPECI rather than by a slower schedule.

Correct answer: Significant Meteorological Information

SIGMET expands to Significant Meteorological Information. It is an in-flight advisory warning of weather hazardous to all aircraft, such as severe icing, severe or extreme turbulence, widespread dust or sandstorms, or volcanic ash. Special Meteorological Instrumentation names equipment rather than an advisory. Supplemental Aeronautical Instructions describes no aviation product at all. Supplementary Atmospheric Observations would describe routine reporting, which is the METAR and SPECI system; the point of a SIGMET is that it is issued only when a hazard is significant.

Correct answer: 24 to 30 hr

A TAF normally covers 24 to 30 hr, since terminal aerodrome forecasts are issued four times a day for 24 hours at most airports and 30 hours at busier ones, describing conditions within about five statute miles of the airport reference point. 42 to 48 hr runs far past the longest routine TAF period, and forecasts reaching that far ahead are area and aviation surface products. 12 to 18 hr is shorter than any standard issue and matches no scheduled valid period. And 30 to 36 hr overshoots the longest TAF by six hours, since 30 hours is the ceiling rather than the start.

Correct answer: MOD TB

Moderate turbulence is reported as MOD TB: MOD is the intensity contraction for moderate and TB is the contraction for turbulence in pilot reports. LGT TB uses the right hazard code but reports light turbulence. SEV TB also names turbulence but at the severe intensity, one step above moderate. SEV IC pairs the severe intensity with IC, the icing field, so it reports severe icing rather than turbulence.

Correct answer: Visual Flight Rules

VFR expands to Visual Flight Rules. These are the rules under which a pilot navigates by outside visual reference and stays responsible for seeing and avoiding other traffic, which is why they carry minimum flight visibility and cloud clearance values. Varied Flight Rules names nothing in the regulations; the rule set does not vary with conditions, the pilot instead switches to IFR. Vector Flight Rules describes radar vectoring, which is a service ATC provides and not a category of flight rules. Volume Flight Rules corresponds to no term in the regulations or in the AIM.

Correct answer: 2 hours before the issued bulletin expires

Correct answer: 2 hours before the issued bulletin expires. A Convective SIGMET is issued for severe thunderstorm activity and carries a maximum valid period of 2 hours, which is short precisely because convection changes quickly and the bulletin is reissued as conditions evolve. 4 hours before the routine advisory lapses is the valid period of a non-convective SIGMET, a different product covering hazards such as severe icing and dust storms. 6 hours before the graphic forecast closes matches the AIRMET, which covers conditions hazardous to lighter aircraft and is a lesser-severity product. 8 hours before the convective outlook ends belongs to a longer-range planning product and is far too long a life for a warning about active thunderstorms.

Correct answer: When immediate turbulence and icing accounts matter most

Correct answer: When immediate turbulence and icing accounts matter most. A pilot report is filed by an airman who has just flown through the conditions, so it is the only routine source that describes turbulence, icing, cloud tops, and ride quality as they are being experienced right now. When upcoming terminal and field predictions matter most points to the terminal aerodrome forecast, which is a prediction for one airport rather than an observation from an aircraft. When official hourly and surface assessments matter most points to the routine surface observation, which is measured at ground level at a fixed site and says nothing about conditions aloft. When long-term monthly and climate forecasts matter most describes planning products with no operational value for a flight about to launch.

Correct answer: Fog, a low-lying cloud from chilled saturation

Correct answer: Fog, a low-lying cloud from chilled saturation. Fog is precisely a cloud in contact with the surface: the air is cooled until it reaches its dew point, becomes saturated, and the excess water vapor condenses into visible droplets. Hail, a banded pellet from repeated suspension, forms as ice is carried up and down inside a strong updraft and accretes layers, which is freezing rather than condensation at the dew point. Dew, a liquid coating from overnight radiation, is water that condenses onto a cold surface, so it is a deposit on objects rather than a cloud suspended in the air. Thunderstorm, a tall column from moist lifting, is a convective cell built by vigorous vertical motion, which is a different process and produces a cloud far above the surface.

Correct answer: PIREP, a crew account from an airborne cockpit

Correct answer: PIREP, a crew account from an airborne cockpit. A pilot report is filed in flight and describes what is actually happening along the route, which makes it the product a remote pilot reaches for when the question is what the weather is doing en route right now. METAR, an hourly observation from a fixed site, is measured at the surface of one airport and describes conditions there rather than along a route. TAF, a terminal prediction from a listed field, is a forecast for the area immediately around a single airport and is a prediction rather than a current report. SIGMET, a storm bulletin from a weather office, warns of specific significant hazards over a broad region and is issued only when such a hazard exists, so it is not a general source of current conditions.

Correct answer: Scattered clouds, covering the middle fractions

SCT stands for scattered clouds, covering the middle fractions of the sky, three to four eighths. Scattered clouds reported within the vicinity would carry the VC prefix, which marks weather near the station, not sky cover. A scattered layer never forms a ceiling at the base; a ceiling is the lowest broken or overcast layer. Scattered showers reported within the vicinity would be coded VCSH, not SCT, which is purely a sky-cover group.

Correct answer: Nearby thunderstorms, ringing the observation station

Correct answer: Nearby thunderstorms, ringing the observation station. The VC prefix means in the vicinity, roughly five to ten statute miles from the point of observation, so VCTS reports thunderstorms near the station but not over it. Constant lightning, battering the observation station, would be encoded as TS without the vicinity prefix, because the phenomenon is occurring at the station itself. Towering cumulus, overhanging the observation station, is encoded TCU and describes a building cloud that has not yet produced a thunderstorm. Expected squalls, approaching the observation station, would appear in a forecast or a change group rather than in the present weather field of a METAR, which reports what is observed now.

Correct answer: The METAR segment reports 1/2 statute mile within fog, short of the 3 SM regulatory threshold.

"1/2SM" is one-half statute mile and "FG" is fog, so the correct reading is: The METAR segment reports 1/2 statute mile within fog, short of the 3 SM regulatory threshold. Under 107.51 the flight is not legal. Mist is coded BR, not FG, and haze is coded HZ, so neither decodes this group. The 1 SM Class G day minimum is a Part 91 manned-aircraft rule under 91.155, and it does not govern Part 107 operations.

Correct answer: Wind flows from 240 degrees true at 15 knots, with intermittent gusts toward 25 knots.

In a METAR wind group the first three digits give direction in degrees true, the next two the sustained speed in knots, and the figure after G the peak gust. So 24015G25KT means wind flows from 240 degrees true at 15 knots, with intermittent gusts toward 25 knots. The magnetic option with gusts toward 25 knots uses the magnetic reference that ATIS and tower broadcasts use, not the METAR's true reference. The option with gusts adding 25 knots also treats the gust as an increment, when 25 is the peak value itself. The option at 25 knots with lulls to 15 knots swaps the sustained speed and the gust.

Correct answer: It is pressure altitude corrected for nonstandard OAT, so thin air badly curbs rotor lift.

Density altitude is pressure altitude corrected for nonstandard temperature, so heat, elevation, and humidity thin the air until propellers produce less thrust and performance degrades. It is not the height of a cloud deck, which drives cloud clearance rather than air density. It is not a level where a barometer stops reading, since barometers keep working in thin air. It is not simply the altimeter indication under standard pressure either, and a higher density altitude cuts thrust and shortens endurance instead of improving them.

Correct answer: Torrid thin air, a mountain airfield well above sea level, plus steamy tropical moisture.

Density altitude climbs with temperature, with elevation, and with moisture, so torrid thin air at a mountain airfield well above sea level with heavy tropical moisture gives the thinnest air and the worst performance. Frigid dense air at a coastal airstrip is the opposite case and yields the lowest density altitude. Chilly stable air under a strong pressure ridge with arid dew points also raises air density rather than lowering it. Higher barometric readings at a low valley strip push air density up as well, so the muggy vapor there cannot offset them.

Correct answer: Forecast visibility runs greater than 6 SM across the entire valid period.

Correct answer: Forecast visibility runs greater than 6 SM across the entire valid period. The P stands for plus, so P6SM forecasts visibility exceeding 6 statute miles, and it holds for the whole of that FM group. Forecast visibility holds at exactly 6 SM through the entire valid period drops the P and reads a floor as a precise value. Forecast visibility sits at 6 nautical miles across the whole valid period misreads SM, which is statute miles in aviation weather. Forecast visibility marks a stated probability of 6 SM inside shallow fog confuses the P with a probability, which a TAF publishes in a separate PROB group and pairs with a named phenomenon.

Correct answer: Stable air, which prevents vertical motion and holds moisture near the cool surface.

Stable air resists vertical motion, so moisture, haze, and fog collect in the lowest layer and surface visibility falls. Unstable air drives brisk upward currents that mix the low levels and carry haze away rather than trapping it. Neutral air under fierce surface warmth also stirs the boundary layer instead of holding moisture down. A temperature inversion is itself a stable condition, but it caps moisture beneath the warm layer rather than hoisting it skyward, so it does not dry the surface.

Correct answer: A dew point close to the temperature signals saturation, so shallow ground mist arises.

A dew point close to the temperature is a small spread, which means the air is near saturation and shallow ground mist or low stratus is likely. A dew point far under the temperature is a wide spread and dry air, so fog is unlikely rather than imminent. A dew point ten degrees over the temperature does not occur in the free atmosphere and would not signal improving visibility anyway. No fixed dew point value such as fifteen Celsius guarantees cloud either; what matters is the spread between the two figures.

Correct answer: Aviation Weather Center products that combine with an FAA channel named 1800wxbrief.com.

The comprehensive briefing comes from Aviation Weather Center products that combine with an FAA channel named 1800wxbrief.com, which together deliver the METARs, TAFs, AIRMETs, SIGMETs and TFR information a remote pilot needs before flight. A consumer smartphone application shows radar and a city forecast while carrying none of those aviation products. A nightly television segment is produced for the general public rather than for preflight planning. And B4UFLY maps airspace and advisories but supplies no weather briefing at all.

Correct answer: The 800 ft overcast leaves 300 ft AGL available, since 107.51 stipulates 500 ft separation.

Correct answer: The 800 ft overcast leaves 300 ft AGL available, since 107.51 stipulates 500 ft separation. OVC008 is an overcast ceiling at 800 ft AGL, and 14 CFR 107.51 requires the aircraft to stay at least 500 ft below the cloud, so only the airspace up to 300 ft AGL remains usable and the planned 200 ft flight complies once that clearance is checked. The 800 ft overcast bars the launch outright, since 107.31 forbids flight beneath a ceiling misstates 107.31, which governs visual line of sight and says nothing about ceilings. The 800 ft overcast matters little, since 107.51 exempts a flight planned below 400 ft AGL invents an exemption, because cloud clearance applies at every altitude flown under Part 107. The 800 ft overcast grounds the flight, since 91.155 demands 1,000 ft of vertical clearance borrows a manned VFR figure that is the distance above cloud, not below.

Correct answer: It defeats steady position hold, drains the main pack fast, and harms precise VLOS control.

Strong gusty wind defeats steady position hold, drains the battery pack faster because the motors fight to stay put, and makes precise control within visual line of sight much harder. Wind does not thicken the air or raise rotor performance; if anything it costs endurance. A flight controller corrects only within its control authority, so the ground track does change once gusts exceed that authority. Part 107 sets no surface wind limit, so 20 knots is not a threshold below which gusts are harmless.

Correct answer: Smooth air and hazy visibility below, with wind shear near the layer's top

This is a temperature inversion: warmer air sits above cooler surface air, so the air below is stable and smooth, and it traps smoke, haze and pollutants, giving poor visibility. A sharp wind shear can sit at the top of the inversion where the calm surface air meets the moving air above. The bumpy-air option gets the shear right but treats the trapped layer as turbulent, and the thermals options assume warm air aloft means rising air when it actually caps vertical motion.

Correct answer: Frost, because the wing is colder than a dew point below freezing

Frost forms when the collecting surface is at or below the dew point of the adjacent air and the dew point is below freezing, so moisture deposits directly as ice. Here the wing (-5°C) is colder than a -2°C dew point, so frost forms even though the air itself is above freezing and unsaturated. Frost on a wing disrupts airflow, reduces lift and raises stall speed, so it must be removed before flight. Dew would need a dew point above freezing, and frozen dew needs liquid dew to form first, which a sub-freezing dew point prevents.

Correct answer: Rain from the cell starting to reach the ground beneath it

The cell described is in the cumulus stage, which is dominated by updrafts. Precipitation beginning to fall from the cloud base to the surface marks the start of the mature stage, when updrafts and downdrafts exist together and turbulence is at its greatest. Downdrafts taking over the entire cell describe the dissipating stage, which comes after the most turbulent period, and updrafts throughout the cell or inflow toward its base still describe the cumulus stage.

Correct answer: Up to about 6,000 ft per minute, seldom over 15 minutes

The AIM states microburst downdrafts can be as strong as 6,000 ft per minute and that an individual microburst seldom lasts longer than 15 minutes from the time it strikes the ground until it dissipates, with outflow winds up to about 45 knots. The 5-minute figure is how long a microburst keeps intensifying after it hits the ground, not its full life. The 45-minute figure borrows the outflow wind speed in knots.

Correct answer: A narrow band of cumuliform clouds and gusty showers, then rapid clearing

A fast-moving cold front lifts warm air abruptly, producing a narrow band of cumuliform clouds, showers and gusty winds, followed by rapid clearing, a wind shift and better visibility behind it. Widespread stratiform clouds with steady rain and slow clearing describe a warm front. The narrow-band stratiform option keeps the fast clearing but gives the front warm-front cloud and rain types.

Correct answer: Stratiform clouds, steady rain, poor visibility, smooth air

Stratiform clouds, steady rain, poor visibility, smooth air is the stable-air set: stable air resists vertical motion, so haze, smoke and pollutants stay trapped near the surface. The most tempting wrong set is the one with good visibility, which assumes calm, stable air means clear air. Showery rain and cumuliform clouds are unstable-air traits, so the remaining two sets mix unstable features into a stable air mass.

Correct answer: Advection fog

Advection fog forms when warm, moist air moves over a colder surface, and unlike radiation fog it can form and persist in winds up to about 15 knots; it is common in coastal areas. Frontal fog is tempting because a warm front is approaching, but it forms when warm rain falls through cooler air, and no rain is falling. Radiation fog needs calm, clear nights and would be mixed out by a 10-knot wind, and upslope fog needs air forced up rising terrain, which level farmland does not provide.

Correct answer: Decreased flight endurance

Adding a payload produces decreased flight endurance: the extra mass needs extra lift, the motors draw more current to make it, and a battery of fixed capacity empties sooner. Decreased motor power draw and decreased flight power use both have the relationship backwards, because heavier aircraft need more power to hover and climb, not less. Decreased takeoff distance is also backwards, since a heavier fixed-wing aircraft needs a longer run to reach its higher takeoff speed.

Correct answer: It reduces stability and degrades pilot control

A shift of the center of gravity means it reduces stability and degrades pilot control, because the balance point moves away from the lift vector and the flight controller must fight the imbalance, sometimes beyond its authority. Saying it cuts endurance but keeps the handling intact gets the side effect right but misses the main hazard, which is handling. Total lift is not cut and handling does not stay unchanged, since moving mass changes balance, not lift. Moving the same load adds no weight and does not reduce the motors' thrust.

Correct answer: The stall speed climbs higher

As weight rises the stall speed climbs higher. Lift must equal weight in level flight and lift grows with the square of speed, so a heavier aircraft needs more speed at the same angle of attack before the wing will hold it up; stall speed scales with √(weight). The stall speed settles lower states the exact inverse of that relationship. The stall speed turns erratic is wrong because for a given configuration and weight the value is determinate rather than unpredictable. The stall speed holds constant would make published maximum weight limits pointless, since they exist precisely because the number moves.

Correct answer: Higher density altitude weakens flight performance

Higher density altitude weakens flight performance, because thinner air gives each propeller revolution less mass to push, so lift, thrust and climb all fall. Lower density altitude reduces lift and the thrust has the direction reversed, since denser air improves both. Lower density altitude reduces climb performance makes the same reversal for climb rate. Higher density altitude adds lift and motor thrust wrongly assumes thin air helps because it creates less drag.

Correct answer: Low altitude and chilly air

The best performance comes with low altitude and chilly air, because cold air near sea level is the densest available, giving the propellers more mass to work with and the lowest density altitude. High elevation and cold air keeps the cold but loses density to the low pressure aloft. Low elevation and humid air is the common trap: water vapor is lighter than dry air, so humidity lowers density rather than raising it. Coastal lowland and hot air keeps the low elevation but heat raises density altitude.

Correct answer: It cuts maneuverability and risks structural damage

Overloading matters because it cuts maneuverability and risks structural damage: the aircraft has less reserve thrust to correct and its arms, mounts and airframe carry loads beyond design limits. It does lengthen the takeoff, but it raises rather than lowers the stall speed. It cuts the climb rate, but it shortens rather than extends flight endurance. And it shortens battery life while increasing, not cutting, motor heating, since the motors work harder throughout.

Correct answer: Higher weight degrades the rate of climb

Higher weight degrades the rate of climb because climb depends on excess power or thrust, and a heavier aircraft spends more of its thrust just staying aloft. Saying higher weight cuts hover, not climb rate, gets the endurance effect right but misses that the climb suffers too. Saying weight raises stall speed, not the climb, borrows a true fixed-wing fact and wrongly leaves climb untouched. Saying higher weight aids both hover and climb reverses the effect entirely, since extra weight costs both.

Correct answer: The added weight the airframe carries through a turn

Load factor is the added weight the airframe carries through a turn: banking or pulling up raises the effective weight the wings, rotors and structure must support, which is why a steep turn loads an aircraft well beyond its static weight. The power output the airframe draws from its engines is a thrust or energy figure, not a load; the top airspeed the airframe reaches in calm flight is a velocity limit; and the total payload mass the airframe can readily lift is a static useful-load rating that does not change with maneuvering.

Correct answer: Flying in humid thin air atop a mountain pass

Performance falls with air density, so flying in humid thin air atop a mountain pass is worst: altitude thins the air and moisture thins it further. Flying in cold thin air above a snowy plateau is high, but cold air is denser, offsetting some of the loss. Flying in hot humid air above a coastal marsh and flying in hot dry air above a sun-baked basin both lower density, but near sea level the altitude loss is far smaller.

Correct answer: A markedly higher chance of a crash

Operating past the maximum takeoff weight brings a markedly higher chance of a crash: structure and motors are loaded past the limits they were tested to, climb rate and control margins shrink, and an overload failure or a power shortfall follows. Extra mass shortens the glide with a stalled motor rather than lengthening it; it raises stall speed in banked turns instead of lowering it, because stall speed climbs with load; and although mass is often expected to damp turbulence, an overloaded craft has less spare thrust to correct a gusty side wind, so the hover degrades.

Correct answer: It cuts the minutes of usable flight time

Extra weight means the motors must produce more thrust just to hold altitude, so it cuts the minutes of usable flight time as the battery drains faster. The load factor in a level turn depends only on bank angle, so weight does not raise it. Weight does not shift the center of gravity forward by itself; that depends on where the load is placed. And the best glide distance from the same height is set by the lift-to-drag ratio, not weight, so extra weight does not extend the glide.

Correct answer: Weaker engine thrust and poorer lift margins

High density altitude means thin air, which gives weaker engine thrust and poorer lift margins because every propeller revolution moves less mass. Less air drag and a longer battery endurance is wrong because the rotors must spin faster in thin air, draining the battery sooner. Lower stall speeds and shorter takeoff rolls reverses the effect, since true airspeed and ground roll both increase. Richer fuel mixture and higher engine output is half right at best: a carbureted engine does run rich at altitude, but its output falls rather than rising.

Correct answer: Aircraft weight and air density

Rate of climb depends on excess thrust over weight, so aircraft weight and air density govern it: a heavier aircraft has less surplus thrust, and thinner air gives the propellers less thrust to work with. Wind speed and flight direction change the ground track and the climb angle over the ground, not the rate through the air. Aircraft balance and wind speed mixes a stability factor with a ground-track factor. Center of gravity and yaw input affect control and handling, not the thrust surplus that sets climb rate.

Correct answer: Endurance shrinks as the payload weight rises

Every extra gram must be held aloft for the whole flight, so endurance shrinks as the payload weight rises, even well below the aircraft's limits. It does not hold steady until the payload tops 55 lb, which is the Part 107 total-weight limit rather than an endurance threshold. It does not hold until the rated payload limit either. And endurance tracks both the battery and the payload, not the battery alone.

Correct answer: Cool morning temperatures at a low coastal airport

Performance is best in dense air, so cool morning temperatures at a low coastal airport give the lowest density altitude and the most lift and thrust. A cold dry winter morning at a high desert airstrip gains from the cold but loses more to the high elevation. Hot dry afternoons at a sea-level desert airstrip lose performance to heat. Warm humid air as a low-pressure system approaches combines heat, water vapor and falling pressure, all of which raise density altitude.

Correct answer: Steadier pitch attitude with a lagging control response

A forward center of gravity buys a steadier pitch attitude with a lagging control response: the airframe resists upsets but answers the sticks sluggishly. It gives less turning authority rather than more, it raises the stalling speed instead of reducing it, and the extra nose-down trim it demands costs endurance rather than lengthening it.

Correct answer: The stall speed increases when the load factor builds

As speed is traded for maneuvering, load factor grows and stall speed climbs with √(load factor): the stall speed increases when the load factor builds. It does not decline as airspeed rises, field elevation moves the indicated stall speed hardly at all, and it does not stay fixed through the flight regime.

Correct answer: It lowers the air density, cutting lift and motor output

Water vapor weighs less than the dry air it displaces, so humid air is thinner: it lowers the air density, cutting lift and motor output. It does not lift the air pressure or add thrust, moisture does not cool the coil windings in any useful way, and it does not soak the blades enough to add drag or weight.

Correct answer: The overall weight of the aircraft

The overall weight of the aircraft is the primary factor in takeoff distance, because a heavier aircraft needs more lift and a higher speed before it can leave the ground. The propeller size of the aircraft and the propeller pitch on an aircraft shape how efficiently thrust is produced, but they are fixed design choices rather than the primary variable. The battery rating of the aircraft limits available power and endurance, yet it is secondary to the load being lifted.

Correct answer: It enhances stability but reduces maneuverability

Correct answer: It enhances stability but reduces maneuverability. Moving the center of gravity forward lengthens the moment arm to the tail or to the rear rotors, which makes the aircraft resist upset and return to its trimmed attitude, at the cost of heavier control response and slower rotation. It increases responsiveness but limits steadiness states the opposite trade and describes an aft center of gravity, which is the less stable and twitchier condition. It strengthens efficiency but restricts endurance confuses balance with power loading, since a forward center of gravity generally costs a little efficiency through added trim drag rather than buying it. It accelerates stalling but simplifies recoveries is backwards on both halves: a forward center of gravity raises stall speed slightly but makes the stall gentler and recovery easier, not the reverse.

Correct answer: It gains extra lift and sheds induced drag

Correct answer: It gains extra lift and sheds induced drag. Close to the surface the ground interrupts the downwash and weakens the wingtip or rotor-tip vortices, so the same power produces more lift while induced drag falls, which is why an aircraft can feel like it floats just above the ground. It drops needed lift and adds surface drag reverses the effect and would describe an aircraft that struggles near the ground, which is not what happens. It holds level lift and doubles rotor drag keeps lift unchanged and invents a large drag penalty, when in fact drag falls. It leaves prior lift and keeps former drag denies the phenomenon altogether, and ground effect is measurable within roughly one rotor or wingspan of the surface.

Correct answer: The loaded weight of the aircraft

The primary factor is the loaded weight of the aircraft, because a heavier machine must reach a greater speed to make the lift that balances it and must accelerate more mass to get there, so distance grows quickly as weight rises. The recorded pressure of the air acts only through density altitude, a correction to the distance rather than the driver of it. The charted elevation of the field works the same indirect way, thinning the air with height while weight remains the primary term. And the measured angle of the airflow trims the ground run through its headwind component, so it adjusts the distance instead of setting it.

Correct answer: High altitude thins air density and cuts overall performance

The true statement is that high altitude thins air density and cuts overall performance: rotors move less mass of air per revolution, so thrust, climb, payload and endurance all fall. High altitude thickens the air is backwards, since air density decreases with height. Parasite drag is lower in thinner air, not higher, so added drag is not the cause. Air pressure also falls with altitude rather than rising, so the motors are not loaded by higher pressure; they must spin faster in thinner air instead.

Correct answer: The aircraft stalls at a higher speed

With weight added, the aircraft stalls at a higher speed, because holding altitude demands more lift and that lift comes from a higher angle of attack or a higher speed, so the critical angle is reached sooner and the usable speed range narrows. The aircraft glides at a flatter angle is wrong, since added weight changes the speed along the glide rather than the angle itself. The aircraft hovers at a lower current is backwards, since supporting a heavier machine draws more current. The aircraft climbs at a quicker rate is also backwards, since climb performance is surplus power divided by weight and falls as weight rises.

Correct answer: Greater flight agility but weaker resistance to gusty upset

Correct answer: Greater flight agility but weaker resistance to gusty upset. Explanation: Moving the center of gravity aft shortens the moment arm that damps pitch, so the aircraft answers control inputs more readily while resisting disturbances less; that is increased maneuverability bought with reduced stability. The opposite pairing, more stability with a duller response, describes a forward center of gravity, not a rearward one. Endurance and battery drain are governed by weight, propeller efficiency and wind rather than by where the balance point sits. A rearward balance does not buy climb performance; it degrades the aircraft's ability to hold an attitude, which is a handling penalty rather than a power gain.

Correct answer: Scorching summer afternoon atop a desert mesa

Correct answer: Scorching summer afternoon atop a desert mesa. Explanation: Performance degrades as air density falls, and heat and elevation both reduce density, so a hot day at a high field elevation produces the highest density altitude and the worst lift, thrust and climb performance of the four. Humid air at sea level is slightly less dense than dry air but the low elevation and moderate temperature keep density altitude near standard. Cold air at altitude is dense for its elevation, and the low temperature partially offsets the height. Cold air at low elevation is the densest of the four and gives the best performance, not the worst.

Correct answer: Strong wind raises the power draw and shortens available flight time

Strong wind raises the power draw and shortens available flight time, because the motors must work continuously to hold position or track against the moving air. Wind does not change the stall speed, which depends on airspeed and weight, so it neither narrows the usable speed band nor raises the stall speed on the downwind leg; that downwind-turn idea is a well-known myth. Density altitude comes from temperature, pressure and humidity, not wind.

Correct answer: The descent rate increases whenever added payload grows heavier

The descent rate increases whenever added payload grows heavier, because more weight needs more lift, so at a given power setting any small UAS sinks faster. Saying it increases for a fixed-wing but not a multirotor is wrong, since a multirotor loaded more heavily also sinks faster. Saying it increases for a multirotor but not a fixed-wing is wrong, since a heavier wing glides faster and sinks faster. The glide ratio is indeed unchanged by weight, but the descent rate still rises.

Correct answer: Under 55 pounds at takeoff, with the UAS wholly loaded, per 107.3.

The limit is under 55 pounds at takeoff, with the UAS wholly loaded, per 107.3, because 14 CFR 107.3 defines a small unmanned aircraft by its takeoff weight including everything on board. Under 55 pounds empty, with its battery packs excluded, per 107.3 wrongly leaves the batteries out of the weighed total. Under 254 pounds empty, with the onboard fuel excluded, per 107.3 borrows the Part 103 ultralight empty-weight figure. Under 55 pounds, or heavier with an FAA waiver issued per 107.205 is wrong because the weight definition is not a waivable section; heavier aircraft need a 44807 exemption instead.

Correct answer: It undermines steady control, since the loaded UAS wanders into unpredictable motion.

A payload that pushes the center of gravity outside the manufacturer's limits has one typical result: It undermines steady control, since the loaded UAS wanders into unpredictable motion. Most flight controllers cannot sense a CG error, so no auto-landing is triggered. The rotors do not share the added weight uniformly; those on the heavy side work harder. And the offset is not only a turbulence problem, because it eats control margin even in calm air.

Correct answer: Thin air starves the rotors, so climb performance plus endurance both shrink.

On a hot, high-elevation day, thin air starves the rotors, so climb performance plus endurance both shrink, and the heavier payload demands still more power from each rotor. Thin air cutting the drag does not offset the payload, because the lost lift costs far more than the saved drag. Warm air aiding the batteries does not keep endurance steady, since the motors must work harder in thin air. Thin air straining the motors reduces endurance as well as the climb rate, so endurance does not hold.

Correct answer: Voltage sags under heavy winter loads, so a reserve safeguards each touchdown.

Battery voltage sags under heavy cold loads and under high demand, so a planned reserve is what protects the touchdown and prevents an in-flight power loss or flyaway. Cells do not recover capacity late in a flight; the indication falls faster near the end. Part 107 fixes no battery reserve at all, so the 30 minute figure is borrowed from manned VFR fuel planning rather than from the rule. And reserve power matters in daylight exactly as much as it does after dark.

Correct answer: Take manual control and fly the craft right home

With the position fix gone, take manual control and fly the craft right home, since the aircraft is still within visual line of sight and the pilot can supply the navigation the satellites no longer do. Hovering in place to wait for the satellite fix drains the pack while the aircraft drifts downwind with nothing holding position. Holding the last heading and pressing on to the target trusts a position the aircraft can no longer update. Climbing above the trees to hunt a stronger signal treats a satellite outage as a control-link problem and carries the aircraft farther from the pilot.

Correct answer: Shielding the public and the property below

Shielding the public and the property below comes first in any emergency, because the remote pilot must never create an undue hazard to people or property on the ground. Notifying ATC and the local FSDO right away is a later step, and a report can wait until the aircraft is down. Flying it back and landing at the home base may carry a failing aircraft over people on the way. Working the checklist and manual right away is a tool for handling the emergency, not the consideration that outranks everything else.

Correct answer: Land the craft in the nearest safe open area

After a mechanical failure the pilot should land the craft in the nearest safe open area, clear of people, while it is still controllable. Engaging return-to-home and flying it to the base keeps a damaged aircraft airborne for the whole trip back. Climbing higher to buy more time to diagnose it is manned-aircraft thinking that only raises the height of a possible fall and may breach 400 feet. Hovering in place to diagnose it using the app keeps a failing aircraft aloft over whatever lies below.

Correct answer: Set the craft down as soon as safely possible

When the command link fails the pilot can no longer control the aircraft, so set the craft down as soon as safely possible, letting any programmed lost-link behavior carry that out. Cycling controller power and resuming the mission, or switching to a backup radio and resuming the mission, both treat the failure as something to work around and keep an unproven link flying. Hovering in place until the data link comes back leaves an uncommanded aircraft aloft on a draining battery with no plan to end the flight.

Correct answer: Send the FAA a written report within ten days

Emergency authority is exercised first and accounted for afterward, so send the FAA a written report within ten days of the deviation. Telling the nearest ATC facility within one hour invents a notification the rule never sets and does nothing for a deviation already flown. Publishing a NOTAM on the path within three days is an airspace notice issued through a flight service facility rather than a pilot's deviation report. And logging the event in the pilot log within one week keeps a private record that never reaches the agency at all.

Correct answer: Get the craft on to the ground within seconds

A failing battery leaves only a very short window, so get the craft on to the ground within seconds while the pack can still control the descent. Engage return-to-home so it lands at the base and fly it back manually, so it lands at the base both spend the last charge on a transit the failing pack may not finish, often over people or obstacles. Hold a hover so that pack voltage can recover mistakes a failure for temporary voltage sag and keeps the aircraft airborne while it loses power.

Correct answer: The safety of persons and the nearby property

In an emergency the remote pilot puts the safety of persons and the nearby property first, and 14 CFR 107.21 allows deviation from the rules to the extent the emergency requires. The safety of the aircraft and the data on it is secondary, because equipment can be replaced. A call to ATC, then the aircraft's own safety, puts communication ahead of protecting people. The safety of the mission and the client data is mission pressure, never the emergency priority.

Correct answer: A jammed GPS signal or a lost position

A jammed GPS signal or a lost position is the usual root of a flyaway, because with no reliable fix the flight controller either drifts with the wind or runs an automatic routine toward a bad home point. A drained LiPo battery or a failed ESC ends the flight with a descent or a crash at a known place rather than an aircraft that wanders off; an overloaded arm or a bent IMU mount hurts stability and attitude sensing without touching navigation; and a strong tailwind or a bad RTH height costs range or obstacle clearance while the aircraft stays under command.

Correct answer: Land the craft and report to the zone authority

After an unintentional incursion, the remote pilot should land the craft and report to the zone authority, the controlling or using agency that owns the restricted area and can warn traffic inside it. Filing a written report to the NTSB is wrong because the NTSB takes accident notifications, not airspace incursions. Reporting to the local police reaches a body with no authority over that airspace. Holding a hover while phoning the FAA leaves the aircraft inside the restricted area for the whole call.

Correct answer: Let the craft run its stored lost link plan

A lost link is planned for before takeoff, so let the craft run its stored lost link plan, which is the behavior the remote pilot programmed and briefed for exactly this case. Waiting quietly for the dead link to come back leaves an uncommanded aircraft aloft with no plan running; climbing high to force the faint link up again assumes a range problem and carries the aircraft farther from the pilot; and dropping down to hand steer once the link fails is not possible, since the lost link is the very channel that hand control would have to travel over.

Correct answer: To harness the whole set of resources for safe flight

CRM exists to harness the whole set of resources for safe flight, meaning people, equipment, information and procedures used together. It does not divide flight resources equally among the crew; tasks are assigned by role and competence. It is not about conserving the aircraft battery and power resources, which is energy management. And it does not pool crew resources so the VO can take command, since the remote pilot in command keeps final authority.

Correct answer: Open talk and firm coordination among the crew

A key element of crew resource management is open talk and firm coordination among the crew, so every member speaks up and actions are meshed on purpose. Shared command and equal votes across the crew misreads CRM: the remote PIC keeps final authority. Group votes on each decision made by the crew likewise removes that authority and slows urgent calls. Full autonomy for each crew member on own task abandons the coordination that CRM is built on.

Correct answer: To spot the hazards and keep the craft visible

The visual observer's most important role is to spot the hazards and keep the craft visible with unaided vision, alerting the remote pilot to traffic, people and obstacles. Watching the video feed and calling out hazards fails because Part 107 requires sight without devices other than corrective lenses. Watching the sky with binoculars is likewise not unaided vision. Watching the airspace and radioing ATC on traffic is wrong because Part 107 gives the VO no ATC role; the VO's report goes to the remote pilot.

Correct answer: Raise the problem on the spot to ensure safety

A duty not being performed is a hazard while the aircraft is flying, so the remote pilot in command should raise the problem on the spot to ensure safety, correcting it through crew communication before it causes harm. Raising the issue at the debrief later leaves the hazard in place for the rest of the flight. Reporting the lapse to the FAA is not required and does nothing for the flight in progress. Covering the job yourself adds to the pilot's workload and hides the breakdown until the debrief.

Correct answer: Talking assertively and listening with real care

Crew resource management turns on talking assertively and listening with real care: a crew member states a concern plainly and the person hearing it genuinely takes it in. Keeping each exchange short and strictly factual is useful radio discipline, but brevity alone never makes a concern get raised or heard; ducking conflict and calmly smoothing team rifts suppresses the very disagreement that surfaces a hazard; and issuing firm orders and expecting instant action is one-way authority, which shuts off the upward flow of information the method depends on.

Correct answer: By lifting the crew talk and the joint choices

CRM cuts human error by lifting the crew talk and the joint choices that follow from it, since shared information and cross-checking catch a mistake before it reaches the aircraft. By automating more of the flight and the route swaps machinery for the human coordination CRM manages and adds fresh failure modes; by leaning harder on the observer and his eyes loads one person rather than spreading the work; and by cutting the roster and the scope of overlap removes the second set of eyes that would have caught the first person's error.

Correct answer: Waving away the calls from the visual observer

Waving away the calls from the visual observer is poor crew resource management, because the pilot discards information from the person placed to watch the airspace. Handing the sticks to a crewmate you supervise is allowed under Part 107 when the remote pilot in command keeps oversight. Letting the observer call for an early landing and halting a flight when a crewmate voices doubt both reflect good communication and a conservative safety culture.

Correct answer: It leaves the crew clear on roles and hazards

A thorough preflight briefing pays off because it leaves the crew clear on roles and hazards before anything is in the air, so nobody improvises a duty or meets a risk unprepared. It lowers the flight hours and the total cost is a budget claim a briefing does not deliver; it hands the pilot command and the whole task describes a briefing that bypasses the crew, which defeats the point of holding one; and it verifies the gear and the spare parts work confuses the briefing with the preflight inspection, which is a separate check of the equipment.

Correct answer: That the crew grasp the duties each was handed

When tasks are delegated, the remote pilot must ensure that the crew grasp the duties each was handed, because 107.49 requires everyone taking part to be briefed on their roles, hazards and procedures. Crew members such as visual observers need no remote pilot certificate, so holding a license is not required. No signed roster naming their roles is required either. Passing the FAA knowledge test is required only of the remote pilot.

Correct answer: It breeds judgment errors and broken crew talk

Stress narrows attention and disrupts teamwork, so it breeds judgment errors and broken crew talk, which is exactly what crew resource management tries to protect. Heavy stress does not make choices more sound, even if it slows the crew. It does not strain one pilot and spare the crew talk, because the stressed person stops sharing information. And it does not tire the crew later while sparing choices now; its effects hit decisions during the flight.

Correct answer: To reach sound choices that keep each flight safe

Aeronautical decision making exists to reach sound choices that keep each flight safe; every other benefit is secondary to that. Shortening the hours a sortie takes is a scheduling aim, managing crew resources is one input to the decision rather than its purpose, and ADM automates nothing the remote pilot does.

Correct answer: Detect the change that calls for a response

DECIDE opens with Detect: detect the change that calls for a response. Estimating what the change requires, identifying the actions available and choosing among them are all genuine steps of the model, but each of them can only follow the moment the change is noticed.

Correct answer: The safety of the whole flight and crew

In aeronautical decision-making the primary focus when weighing alternatives is the safety of the whole flight and crew, which outranks every other consideration. The safety of the drone and its payload protects property, which is secondary to people. The speed of the choice and its outcome reflects time pressure that ADM training warns against letting drive a decision. The value of the drone and its payload is a cost concern, not the ranking standard.

Correct answer: It keeps the pilot focused and ahead of events

A preflight checklist keeps the pilot focused and ahead of events, which is the value ADM draws from it. Confirming the gear is packed is a packing list rather than a decision aid, no checklist removes the whole risk of failure, and any saving in setup time is a side effect rather than the benefit.

Correct answer: Work the DECIDE model and pick the safest hazard action

The appropriate response is to work the DECIDE model and pick the safest hazard action, running detect, estimate, choose, identify, do and evaluate in that order. Calling ATC and handing the hazard decision to the controller misplaces authority, because the remote pilot in command stays responsible for the operation and ATC issues no instructions to a Part 107 flight. Landing and shedding the remaining hazard options fast discards alternatives that may be safer than an immediate landing, such as repositioning away from the hazard. Logging the hazard into a printed NOTAM is not something a remote pilot can do, and continuing onward leaves the hazard unaddressed.

Correct answer: By training regularly and tracking the rule changes

A remote pilot improves decision making by training regularly and tracking the rule changes, so judgment is exercised on varied scenarios and stays current. Trusting the autopilot so fewer choices are made breeds automation complacency and lets the skill decay. Flying calm days so that hard calls seldom arise avoids exactly the practice that builds judgment. Memorizing checklists and setting judgment aside confuses procedures with decisions; checklists support aeronautical decision making but never replace it.

Correct answer: Delay the flight and wait for better conditions

When pressured to fly in unsafe conditions, the pilot should delay the flight and wait for better conditions; the remote pilot in command is the final authority and the hazard, not the schedule, sets the launch. Shortening the flight and briefing two more observers adds mitigation but still flies into the unsafe condition. Briefing the crew and flying low in calmer conditions trades one hazard for obstacle risk and still launches. Briefing the client and flying under stricter limits lets commercial pressure decide the go or no-go.

Correct answer: An anti-authority attitude toward the operating rules

Of these, the hazardous one is an anti-authority attitude toward the operating rules, one of the five FAA hazardous attitudes alongside impulsivity, invulnerability, macho and resignation. An assertive attitude toward a teammate's safety call is a crew resource management skill, not a hazard. A skeptical attitude toward the automated flight mode guards against automation complacency rather than creating risk. A cautious attitude toward the drone's loading limits is ordinary sound airmanship and appears on no list of hazardous attitudes.

Correct answer: It draws out candid input from the whole crew

Crew resource management draws out candid input from the whole crew, so more information reaches the decision before it is made. It does not reduce the number of decisions to be made, no process wipes out the prospect of a collision, and leaving every call to a lone pilot is the opposite of what CRM asks for.

Correct answer: Brushing off each of the latest weather updates

Brushing off each of the latest weather updates is a sign of poor decision making, the invulnerability pattern that discards the information the next decision depends on. Letting the observer relay every weather update is sound crew resource management. Revising the plan after each new weather update is exactly the continuous reassessment good aeronautical decision making calls for. Delaying the launch for the next weather update is a conservative, sound choice rather than a poor one.

Correct answer: When human safety or property protection demands it

Under 14 CFR 107.21 the remote pilot in command may deviate from any rule of Part 107 to the extent needed to meet an in-flight emergency, that is, when human safety or property protection demands it, and must report in writing if the FAA asks. ATC clearance or LAANC authorization governs planned access to controlled airspace, not emergency authority. A waiver or prior FAA authorization is arranged in advance for planned operations. The observer's report or flight plan may prompt a change, but neither is what authorizes the deviation; the emergency is.

Correct answer: Suspend the flight and reestablish awareness then resume

Correct answer: Suspend the flight and reestablish awareness then resume. Explanation: The recommended response to lost situational awareness is to stop adding new demands, hold the aircraft in a stable low-workload state, rebuild an accurate picture of position, traffic and battery state, and only then continue the mission. Climbing to broaden visual coverage puts the aircraft closer to manned traffic and can push it beyond the 400 ft AGL limit while the pilot is still disoriented. Handing the aircraft to an automated retrieve routine surrenders control at the moment the pilot least understands where the aircraft is and what lies along the return path. Continuing at a steadier groundspeed keeps the aircraft moving through the very airspace the pilot can no longer account for.

Correct answer: Land soon and recover the aircraft once weather permits

When the weather changes suddenly, the remote pilot should land soon and recover the aircraft once weather permits, rather than keeping it airborne in deteriorating conditions. Hovering low in a building's lee seems sheltered but puts the aircraft in mechanical turbulence beside an obstacle. Climbing above the gusts to wait for the weather to pass risks the altitude limit, cloud clearance and stronger winds aloft. Keeping flying in a wind-resist mode is mission pressure that drains the battery while conditions worsen.

Correct answer: Land the aircraft at the first clearly safe opportunity

After an onboard system failure the immediate priority is to land the aircraft at the first clearly safe opportunity, before one fault cascades into a loss of control. Landing at the launch point by its home route keeps a failing aircraft airborne for the whole trip back. Landing once the full fault checklist is done delays the landing for troubleshooting the failure may not allow. Landing at the launch point after a hover adds both a hover and a transit while the fault persists.

Correct answer: Land promptly and notify the FAA or controlling agency

After an unintended entry the pilot should land promptly and notify the FAA or controlling agency, the body named on the chart that owns the restricted area. Notifying the nearest airport ATC tower or the local airport's ATC tower reaches a facility that does not control the restricted area. Filing a NASA safety report in 10 days is a voluntary ASRS filing that can limit penalties but does not inform the agency responsible for the airspace.

Correct answer: Address the concerns and revise the plan where needed

The remote pilot should address the concerns and revise the plan where needed, because crew resource management only works if a concern is weighed before launch and the plan changes when the concern is sound. Recording the concerns for review after landing means the flight goes ahead with the hazard still in place. Handing the decision to the crew member gives away authority that stays with the remote pilot in command. Reassuring the member and re-explaining the unchanged plan treats the concern as a misunderstanding rather than as information.

Correct answer: Deliver a full preflight briefing listing the flight hazards

The best way is to deliver a full preflight briefing listing the flight hazards to the whole crew, which is required under 107.49 and confirms everyone heard each hazard and its planned response. Posting a printed list at the launch site assumes each member reads it and gives no chance for questions. Briefing the senior visual observer to relay the flight hazards adds a second-hand link where details are lost. Handing every crew member a site map marks locations but not the procedures or responses the briefing covers.

Correct answer: Encouraging open crew dialogue and inviting each member's view

Teamwork improves most by encouraging open crew dialogue and inviting each member's view, so a visual observer or payload operator speaks up before a hazard becomes an incident. Holding crew remarks until landing misapplies the sterile-cockpit idea and suppresses the warnings the RPIC needs in flight. Debriefing errors only after a mishap and logging who erred builds blame rather than communication. Routing every report through the VO to spare the RPIC noise delays and filters time-critical information.

Correct answer: Across each flight phase from planning to final shutdown

Crew resource management applies across each flight phase from planning to final shutdown: planning, the preflight brief, launch, the operation, recovery and the debrief all depend on sound workload, communication and decision habits. From launch through recovery while the craft is airborne drops the planning and shutdown phases, where many errors are set up. During launch and landing while the craft is near people limits it to the busiest moments and leaves cruise unmanaged. Whenever a visual observer or a co-pilot shares the work ties it to crew size, yet a solo remote pilot still applies CRM to manage workload and self-assessment.

Correct answer: Evaluate the outcome that the chosen action has produced

Correct answer: Evaluate the outcome that the chosen action has produced. Explanation: The DECIDE loop runs Detect, Estimate, Choose, Identify, Do and Evaluate, so the closing step is judging whether the action taken actually fixed the problem and left the flight safe; without it the loop never closes and a bad choice goes uncorrected. Detecting a hazard that needs attention is the opening step, not the closing one. Carrying out the chosen solution is the Do step that immediately precedes evaluation. Identifying candidate actions sits in the middle of the sequence, before anything has been done at all.

Correct answer: To guide a structured flight review before each launch

Correct answer: To guide a structured flight review before each launch. The 5P checklist covers the Plan, the Plane, the Pilot, the Passengers and the Programming, and its function is to force a repeatable sweep of the factors that decide whether a flight should go, at points where a pilot might otherwise skip one. To forecast the sky conditions across each launch site is not a weather product, since the checklist prompts the pilot to consider the forecast but produces none. To appraise the piloting ability of every crew member is a competency assessment, and the checklist grades no one and issues no rating. To compute an escape route after every sudden breakdown is an output a pilot may build from the review, not the purpose of the checklist.

Correct answer: Rejecting the safety rules published by an outside regulator

Anti-Authority is rejecting the safety rules published by an outside regulator, the don't-tell-me mindset that leads to altitude busts and unauthorized entries into controlled airspace; its antidote is that rules are usually right. Breaking altitude rules just to show off flying prowess is the Macho attitude, where the motive is proving skill. Ignoring the rules because mishaps happen to other operators is Invulnerability. Skipping the preflight rules to launch before assessing risk is Impulsivity, doing something quickly rather than resenting authority.

Correct answer: A drive to reach the destination despite safety hazards

Correct answer: A drive to reach the destination despite safety hazards. Explanation: Get-There-Itis is the fixation on arriving that makes a pilot discount deteriorating weather, dwindling battery or a failing component because the destination is close; it is dangerous precisely because the pilot keeps flying past the point where the plan should have been abandoned. External pressure from a client sets up the fixation but is not the term itself. A wish to finish quickly describes schedule efficiency, not the refusal to divert. Confidence built from a run of uneventful flights is Invulnerability, a separate hazardous attitude.

Correct answer: Anti-authority, the posture that shrugs off a written procedure.

The antidote "Follow the rules; they are usually right" answers anti-authority, the outlook that shrugs off a written procedure. Impulsivity is the urge to act on a first idea, and its antidote is "Not so fast, think first." Invulnerability is the belief that accidents strike the other pilot, answered by "It could happen to me." Resignation is the sense that outcomes sit beyond personal control, answered by "I am not helpless." The five hazardous attitudes are anti-authority, impulsivity, invulnerability, macho, and resignation.

Correct answer: Invulnerability, answered by the reminder that harm reaches you.

Believing that an accident will not happen to you is invulnerability, answered by the reminder that mishaps reach anyone, and recognizing personal risk is what drives a thorough preflight. Macho is the urge to prove skill by taking chances, a different thought entirely. Resignation is the belief that effort no longer matters, which is not what skipping an inspection expresses. Anti-authority is contempt for the rules themselves rather than a belief in personal immunity.

Correct answer: Detect a variation and evaluate it, then intervene and reassess consequences.

Aeronautical decision-making and the DECIDE model give the remote pilot a structured way to detect a change and weigh it, then act and review results, which is how risk is managed in flight. They do not compute density altitude or balance figures; those come from performance charts and a weight and balance calculation. They do not require memorizing the regulations word for word. And no decision model erases operational hazards or residual risk, because risk is managed rather than removed.

Correct answer: Let the lost-link RTH routine run and keep bystanders clear.

A prepared remote pilot lets the lost-link RTH routine run and keeps bystanders clear, because the aircraft's programmed behavior is already known and the people under the flight path are what needs protecting. Leaving the ground control station abandons the operation at the moment supervision matters most. Killing transmitter power destroys the link the aircraft might still reacquire and invites an uncontrolled descent. Telephoning air traffic control and the FAA is a later reporting step, not the first response.

Correct answer: It slows reaction, clouds judgment, and badly erodes VLOS situational awareness.

Fatigue most directly works on the mind: it slows reaction, clouds judgment, and badly erodes VLOS situational awareness, so a tired pilot sees traffic late and decides poorly. Euphoria and inflated confidence are the signature of hypoxia, not fatigue. Vertigo and a tilted horizon describe spatial disorientation from vestibular illusions. An adrenaline spike with tunneled attention is the acute-stress response, a separate hazard; fatigue dulls arousal rather than spiking it.

Correct answer: Rods beat cones in darkness, so a sideways glance catches faint shapes.

The rods that carry night vision lie outside the central fovea and are more sensitive than the cones in darkness, so a sideways glance catches faint shapes that central vision misses. Cones work best in bright light rather than dim light, so resting them is not the mechanism. Off-center viewing never replaces the anti-collision lighting required for night operations. And color vision belongs to the cones; rods are essentially colorblind.

Correct answer: Impulsivity, cured by a deliberate pause for unhurried reflection.

The rushed launch is impulsivity, cured by a deliberate pause for unhurried reflection, which is the textbook antidote "Not so fast. Think first." Impulsivity, cured by the sober view that big chances are foolish names the right attitude but borrows the macho antidote. Macho, cured by the sober conviction that big chances are foolish is the correct pairing for macho, but the pilot is not trying to prove anything, only acting fast. Impulsivity, cured by obeying the rules, as they are usually right attaches the anti-authority antidote to the wrong attitude.

Correct answer: It assembles available crew expertise and hardware for safer UAS decisions.

Crew Resource Management exists so that it assembles available crew expertise and hardware for safer UAS decisions, using every person and piece of equipment deliberately. Splitting workload never transfers legal liability from the RPIC to VOs; the remote pilot in command stays directly responsible under 107.19. Ranking crew positions does not grant the VO equal authority over RPIC orders, because final authority stays with the RPIC. And CRM is not a record-keeping scheme; the FAA does not audit archived crew briefings.

Correct answer: They bring drowsiness and slow reaction, so judgment and alertness both fade.

Sedating antihistamines are a hazard because they bring drowsiness and slow reaction, so judgment and alertness both fade. And 14 CFR 107.17 bars flying with any condition that interferes with safe operation. The 8-hour rule governs alcohol, not medication, and a sedating drug disqualifies for as long as its effects last. These drugs do not add to blood alcohol content, so the 0.04 percent limit does not measure them. And over-the-counter antihistamines are not banned drugs; taking one does not void a remote pilot certificate, it only makes flying unsafe while it acts.

Correct answer: Ground the aircraft and replace the frayed propeller, since cracks widen.

The pilot should ground the aircraft and replace the frayed propeller, since cracks widen under load and a blade failure means loss of control; 14 CFR 107.15 bars flight unless the aircraft is in a condition for safe operation. Sanding and rebalancing the blade leaves weakened material spinning at speed. Trimming the frayed propeller tips changes balance and length while the damage remains. Taping and rebalancing the blade only hides the defect and adds an unbalanced mass.

Correct answer: Saturation splits attention, since one fixation hides the nearby surroundings entirely.

Task saturation splits attention: the pilot fixates on one demanding task and loses track of the aircraft and surroundings, so the answer is saturation splits attention, since one fixation hides the nearby surroundings entirely. Dulled vigilance from having too little to do describes underload, the opposite condition. Disorientation from conflicting motion cues is spatial disorientation, a vestibular problem rather than a workload one. Complacency on a routine flight is another low-workload hazard and does not describe what saturation does to awareness.

Correct answer: Resignation, met by the thought that effort changes things.

Feeling that the outcome is out of your hands is resignation, met by the thought that effort changes results, the antidote "I am not helpless, I can make a difference." Macho is the urge to prove skill by taking chances. Anti-authority is contempt for rules that mostly help. Invulnerability is the belief that mishaps reach everyone else and not you. Only resignation describes a pilot who has stopped trying to influence the outcome.

Correct answer: 118.3

A star after the tower frequency means the tower operates part-time, and the C in a solid circle after 118.3 marks it as the CTAF, so when the tower is closed pilots self-announce on 118.3. The UNICOM frequency 122.95 is a tempting choice because CTAF is often the UNICOM at non-towered fields, but here the chart assigns the CTAF to the tower frequency. ATIS 125.25 is a recorded broadcast, and 122.9 MULTICOM is used only where no tower, FSS or UNICOM is available.

Correct answer: North of the runway, flying east

Runway 27 is landed on heading west (270 degrees), and the downwind leg is flown parallel to the runway in the opposite direction, so the aircraft is heading east. Right traffic puts the pattern on the right side of the landing direction; facing west, the right side is north. North of the runway flying west wrongly assumes downwind is flown in the runway direction, and south of the runway flying east is where left traffic for runway 27 would be.

Correct answer: South of the Piper, two miles away

The answer is south of the Piper, two miles away. Traffic clock positions are measured from the nose of the aircraft receiving the call, with 12 o'clock straight ahead and 3 o'clock off the right wing, and the right wing of an east-bound aircraft points south. East comes from treating the clock as fixed to north (3 o'clock = 090). North comes from counting the clock the wrong way (off the left wing), and west comes from making both errors.

Correct answer: Keep listening without transmitting and steer the drone clear of the Cessna

The answer is to keep listening without transmitting and steer the drone clear of the Cessna. The FAA Remote Pilot Study Guide says remote pilots should monitor the frequency for awareness but refrain from transmitting on an active aviation frequency unless there is an emergency, and Part 107 requires the drone to yield right of way to manned aircraft. Broadcasting the drone's position sounds helpful, but it is the transmission the guidance tells remote pilots to avoid, and a UNICOM relay or a direct call to the Cessna puts the same unneeded traffic on the frequency.

Correct answer: 122.9 MHz, the MULTICOM frequency

The answer is 122.9 MHz, the MULTICOM frequency. The AIM's communication table says that at an airport with no tower, FSS or UNICOM, pilots self-announce on MULTICOM 122.9, and the Remote Pilot Study Guide gives the same rule for airports with no frequency listed. 122.8 is the most common UNICOM, but UNICOM is the CTAF only where a UNICOM is published, and 123.0 is also a UNICOM assignment. 121.5 is reserved for emergencies.

Correct answer: The ceiling is above 5,000 feet and visibility is more than 5 miles

The answer is that the ceiling is above 5,000 feet and visibility is more than 5 miles. AIM 4-1-13 allows the ceiling/sky condition, visibility and obstructions to vision to be left out of an ATIS only under those conditions. 3,000 feet and 5 miles is the boundary between VFR and marginal VFR, not the ATIS omission rule. 1,000 feet and 3 miles are the basic VFR minimums. 900 feet and 3 miles is a Part 107 figure (400 feet plus 500 feet below clouds, with 3 miles visibility), not an ATIS rule.

Correct answer: External pressures; warn the client in advance delivery may slip

The answer is External pressures; warn the client in advance delivery may slip. A deadline set by someone else creates pressure to finish a flight and falls in the E of PAVE, and the handbook's remedy is to manage expectations ahead of time (for example, telling those waiting that a delay is possible) and to rely on personal minimums. Launching early to beat the wind names the right category but gives in to the pressure. IMSAFE and the wind check are sound steps for the Pilot and enVironment categories, but the deadline belongs to neither.

Correct answer: High risk on the FAA matrix

The answer is high risk on the FAA matrix. An event expected to occur several times is 'probable,' and severe injury or major damage is 'critical,' and the probable/critical cell of the handbook's matrix is high. High risk means the pilot should not fly unless the risk is mitigated, eliminated or controlled. Serious is what results if the likelihood is underrated as occasional or the severity as marginal (minor injury). Medium and low sit in the less likely rows and less severe columns, which a dropout already seen several times, with severe injury possible, does not fit.

Correct answer: Macho, countered by: Taking chances is foolish.

Trying to prove skill by taking a risk to impress someone ("I can do it, I'll show them") is the macho attitude, and the FAA antidote for macho is "Taking chances is foolish." Invulnerability is the tempting pick because the pilot is shrugging off the wind, but invulnerability is the belief that accidents happen to other people ("It won't happen to me"), not a bid to impress an audience. "It could happen to me" is the antidote to invulnerability, so pairing it with macho swaps the antidotes. Nothing here is a rush to act without thinking, which is what impulsivity describes.

Correct answer: Occasional and critical, which the matrix rates serious

The FAA defines occasional as an event that will probably occur sometime, while probable means it will occur several times. Severe injury or major damage is critical, not catastrophic (fatalities or total loss), and occasional combined with critical falls in the serious cell of the PHAK matrix. The probable-and-critical pick is tempting because the stem says 'probably', but one expected occurrence is occasional. Remote and catastrophic reaches the serious label through two misclassifications.

Correct answer: Experience should be Emotion; recency is a PAVE pilot item

Experience should be Emotion; recency is a PAVE pilot item is correct: the current handbook lists Illness, Medication, Stress, Alcohol, Fatigue and Emotion, while experience and currency are questions under the Pilot element of PAVE. Eating is the most tempting wrong choice because some older training materials used it for the E, but the current handbook uses Emotion. Alcohol is its own IMSAFE item, so neither Attitude nor Anxiety replaces it.
