Correct Answer: A. Explanation: "Get-There-Itis" is a hazardous attitude where pilots feel compelled to complete their mission despite unsafe conditions, increasing the risk of accidents.
- When operating near an airport, what is the purpose of communicating with ATC as a remote pilot?
- To obtain a weather update
- To request permission to enter controlled airspace
- To receive clearance for taxi operations
- To coordinate refueling operations
Correct answer: To request permission to enter controlled airspace
Correct answer: B. Explanation: When operating a UAS near an airport in controlled airspace, remote pilots must communicate with ATC to request and receive authorization to enter the airspace.
- What is the significance of two white lights and two red lights on a Precision Approach Path Indicator (PAPI) system?
- The aircraft is too high
- The aircraft is too low
- The aircraft is on the correct glide path
- The runway is closed
Correct answer: The aircraft is on the correct glide path
Correct answer: C. Explanation: A PAPI system provides visual guidance for pilots during approach; two white and two red lights indicate that the aircraft is on the correct glide path.
- What is the significance of calibrating the UAS compass during preflight?
- To increase battery life
- To ensure accurate GPS navigation and heading
- To improve camera focus
- To adjust the flight control settings
Correct answer: To ensure accurate GPS navigation and heading
Correct answer: B. Explanation: Compass calibration ensures the UAS follows the correct heading and navigates accurately based on GPS data.
- How should a remote pilot handle discrepancies found in the UAS maintenance log?
- Report the discrepancies to the manufacturer
- Ignore them if they seem minor
- Ensure the discrepancies are addressed before flying
- Reschedule the flight
Correct answer: Ensure the discrepancies are addressed before flying
Correct answer: C. Explanation: Any discrepancies in the maintenance log should be corrected before flight to ensure safe operation.
- Why should a UAS be inspected after every flight?
- To adjust the payload
- To verify that no components were damaged during the flight
- To recharge the battery
- To prepare for the next flight
Correct answer: To verify that no components were damaged during the flight
Correct answer: B. Explanation: Post-flight inspections help identify any wear or damage that occurred during flight, preventing future safety issues.
- A sectional chart shows an airport surrounded by a solid magenta circle, with the notation "41/SFC" displayed inside a segmented box near the boundary. What airspace is depicted and what authorization does a remote pilot need to operate there?
- Class C airspace extending from the surface up to 4,100 ft MSL; prior ATC authorization is required.
- Class D airspace from the surface to 4,100 ft AGL; no authorization is required.
- Class E airspace beginning at 4,100 ft MSL; only a NOTAM check is required.
Correct answer: Class C airspace extending from the surface up to 4,100 ft MSL; prior ATC authorization is required.
Solid magenta circles depict Class C airspace, and the box reading "41/SFC" means the airspace tops out at 4,100 ft MSL and extends down to the surface. Operations in Class C require prior ATC authorization, typically obtained through LAANC.
- On a sectional chart, an airport is enclosed by a dashed blue circle. The remote pilot wants to fly within that circle. What type of airspace is this, and what is required before launching?
- Class D airspace; prior ATC authorization is required before operating.
- Class E surface airspace; no authorization is required.
- Class G airspace; only a self-announce on CTAF is required.
Correct answer: Class D airspace; prior ATC authorization is required before operating.
A dashed blue line depicts Class D airspace, which is controlled airspace requiring prior ATC authorization (e.g., via LAANC) for sUAS operations under 14 CFR 107.41.
- A remote pilot sees an area on the sectional enclosed by a dashed magenta line surrounding a small airport. What does this depict?
- Class E airspace that extends down to the surface, designated to protect instrument approaches.
- Class B airspace with a floor at 700 ft AGL.
- A military operations area (MOA) active only during published hours.
Correct answer: Class E airspace that extends down to the surface, designated to protect instrument approaches.
A dashed magenta line indicates Class E airspace that begins at the surface, typically established around airports to protect instrument approach and departure procedures.
- An airport on the sectional lies beneath a Class C shelf depicted by a segmented box reading "41/12." What do these numbers represent?
- The shelf top is 4,100 ft MSL and its floor is 1,200 ft MSL.
- The shelf top is 41,000 ft MSL and its floor is 12,000 ft MSL.
- The shelf extends from 4,100 ft AGL down to the surface.
Correct answer: The shelf top is 4,100 ft MSL and its floor is 1,200 ft MSL.
In an airspace box, the top number is the ceiling and the bottom number is the floor, expressed in hundreds of feet MSL. "41/12" means a ceiling of 4,100 ft MSL and a floor of 1,200 ft MSL. Below 1,200 ft MSL in that area would be Class G or E.
- A magenta vignette (faded magenta shading on the inside of a line) surrounds an area on the sectional chart. What is the floor of the Class E airspace it represents?
- 700 ft AGL.
- 1,200 ft AGL.
- The surface.
Correct answer: 700 ft AGL.
A faded magenta vignette indicates Class E airspace with a floor of 700 ft AGL. A faded blue vignette indicates a Class E floor of 1,200 ft AGL.
- A remote pilot plans to operate in airspace shown on the sectional as having no surrounding solid or dashed colored airspace lines and no shading near the ground. The operating area is below 1,200 ft AGL in this region. What airspace class is this, and what authorization is needed?
- Class G (uncontrolled) airspace; no ATC authorization is required.
- Class E airspace; LAANC authorization is required.
- Class B airspace; a DroneZone waiver is required.
Correct answer: Class G (uncontrolled) airspace; no ATC authorization is required.
Class G is uncontrolled airspace and requires no ATC authorization for Part 107 operations, though the pilot must still comply with all other Part 107 rules.
- On a sectional chart, an airport is encircled by a solid blue line. A remote pilot wishes to operate within it. What airspace is depicted and what must the pilot do?
- Class B airspace; the pilot must obtain prior ATC authorization before operating.
- Class C airspace; the pilot only needs to monitor CTAF.
- Class E airspace; no authorization is required below 400 ft AGL.
Correct answer: Class B airspace; the pilot must obtain prior ATC authorization before operating.
Solid blue lines depict Class B airspace. Part 107 operations in Class B require prior ATC authorization under 14 CFR 107.41, typically obtained through LAANC.
- A remote pilot examining a sectional finds a Class C airport. The inner core ring shows "41/SFC" and an outer shelf ring shows "41/13." The pilot wants to fly at 200 ft AGL directly beneath the outer shelf, where the terrain elevation is about 600 ft MSL. Is ATC authorization required?
- No, because the operation at roughly 800 ft MSL is below the 1,300 ft MSL shelf floor and in uncontrolled airspace.
- Yes, because any operation under a Class C shelf is inside Class C airspace.
- Yes, because the operation is within 5 NM of a Class C airport.
Correct answer: No, because the operation at roughly 800 ft MSL is below the 1,300 ft MSL shelf floor and in uncontrolled airspace.
The shelf floor of 1,300 ft MSL means the Class C airspace does not begin until that altitude in the shelf area. A flight at about 800 ft MSL is below the shelf and therefore in uncontrolled airspace, so no Class C authorization is required.
- What is the maximum altitude a small unmanned aircraft may be operated under Part 107 without a waiver, and what is the exception?
- 400 ft AGL, unless flown within a 400 ft radius of a structure, then up to 400 ft above the structure's immediate uppermost limit.
- 500 ft AGL, with no exceptions for structures.
- 400 ft MSL regardless of terrain or structures.
Correct answer: 400 ft AGL, unless flown within a 400 ft radius of a structure, then up to 400 ft above the structure's immediate uppermost limit.
Per 14 CFR 107.51, the maximum altitude is 400 ft AGL, or higher if within 400 ft of a structure (up to 400 ft above the structure's immediate uppermost limit).
- A remote pilot wants to operate in controlled airspace near a towered airport that participates in LAANC. What does LAANC provide?
- Near-real-time authorization to operate in controlled airspace up to published ceiling altitudes shown in UAS Facility Maps.
- A blanket waiver from all Part 107 operating limitations.
- Automatic clearance to fly above 400 ft AGL anywhere in the country.
Correct answer: Near-real-time authorization to operate in controlled airspace up to published ceiling altitudes shown in UAS Facility Maps.
LAANC (Low Altitude Authorization and Notification Capability) provides near-real-time ATC authorization for controlled airspace operations up to the ceiling altitudes published in UAS Facility Maps.
- A temporary flight restriction (TFR) has been issued over a stadium during a major sporting event. What is the remote pilot's obligation?
- The pilot must not operate within the TFR's lateral and vertical limits unless specifically authorized.
- The pilot may operate freely as long as the drone stays below 400 ft AGL.
- The pilot may operate if a spotter maintains visual line of sight at all times.
Correct answer: The pilot must not operate within the TFR's lateral and vertical limits unless specifically authorized.
TFRs restrict flight operations in a defined area. A remote pilot must check for and comply with active TFRs and may not operate inside one without specific authorization. Stadium TFRs apply to large sporting events.
- Before a flight, a remote pilot should check NOTAMs primarily to learn about what?
- Temporary hazards or changes such as TFRs, closed runways, or unlit obstructions affecting the operating area.
- The current density altitude at the destination airport.
- The registration status of nearby aircraft.
Correct answer: Temporary hazards or changes such as TFRs, closed runways, or unlit obstructions affecting the operating area.
NOTAMs (Notices to Air Missions) provide time-critical information about temporary conditions such as TFRs, airspace changes, and obstructions that are essential to preflight planning.
- At a non-towered airport within Class G airspace, a remote pilot hears manned aircraft announcing positions on a frequency. What is this frequency called and what should the remote pilot do?
- The Common Traffic Advisory Frequency (CTAF); the pilot should monitor it to maintain awareness of nearby manned traffic.
- The Air Route Traffic Control Center frequency; the pilot must obtain a clearance on it before launching.
- The Automatic Terminal Information Service; the pilot must broadcast their flight plan on it.
Correct answer: The Common Traffic Advisory Frequency (CTAF); the pilot should monitor it to maintain awareness of nearby manned traffic.
The CTAF is used for self-announced position reports at non-towered airports. Monitoring it helps a remote pilot maintain situational awareness and yield to manned aircraft, which always have right of way under 14 CFR 107.37.
- A remote pilot encounters an area on the sectional marked as a Restricted Area (e.g., "R-2503") with published altitudes and times. What does this designation mean?
- Flight within it may be hazardous and is subject to restrictions; permission from the controlling agency is required when it is active.
- It is a recommended VFR practice area open to all aircraft at any time.
- It is permanently closed to all aircraft including military.
Correct answer: Flight within it may be hazardous and is subject to restrictions; permission from the controlling agency is required when it is active.
Restricted Areas contain hazards such as artillery firing or guided missiles. When active, entry requires permission from the controlling or using agency.
- A sectional shows a Class B airport with the airspace box for one tier reading "100/30." The remote pilot is at a location under this tier. What does this indicate about the Class B floor and ceiling there?
- The Class B ceiling is 10,000 ft MSL and the floor is 3,000 ft MSL at that location.
- The Class B ceiling is 1,000 ft MSL and the floor is 300 ft MSL.
- The Class B extends from the surface to 13,000 ft MSL.
Correct answer: The Class B ceiling is 10,000 ft MSL and the floor is 3,000 ft MSL at that location.
Numbers in airspace boxes are in hundreds of feet MSL: "100/30" means a ceiling of 10,000 ft MSL and a floor of 3,000 ft MSL. Class B airspace is layered like an upside-down wedding cake with different floors in each tier.
- A remote pilot wishes to operate in Class E surface airspace (depicted by a dashed magenta line) around a non-towered airport. Is ATC authorization required?
- Yes, because Class E that extends to the surface is controlled airspace requiring authorization under Part 107.
- No, because all Class E airspace is uncontrolled for sUAS.
- No, because the airport is non-towered.
Correct answer: Yes, because Class E that extends to the surface is controlled airspace requiring authorization under Part 107.
Class E airspace designated to the surface is controlled airspace. Under 14 CFR 107.41, operations there require prior ATC authorization, even at a non-towered airport.
- A METAR reports: "...VIS 1/2SM FG..." Which condition is being reported and how would it affect a Part 107 operation?
- Visibility is 1/2 statute mile in fog, which is below the 3 statute mile minimum required for Part 107 operations.
- Visibility is 1/2 nautical mile in light rain, which still meets Part 107 minimums.
- Visibility is 12 statute miles in fog, which exceeds Part 107 minimums.
Correct answer: Visibility is 1/2 statute mile in fog, which is below the 3 statute mile minimum required for Part 107 operations.
"1/2SM" means one-half statute mile visibility and "FG" is the METAR code for fog. Part 107 requires at least 3 statute miles of flight visibility from the control station (14 CFR 107.51), so this operation would not be legal.
- A METAR includes the group "24015G25KT." What does this tell the remote pilot about the wind?
- Wind is from 240 degrees true at 15 knots, gusting to 25 knots.
- Wind is from 150 degrees at 25 knots, with a 24-knot crosswind.
- Wind is variable at 240 knots with gusts.
Correct answer: Wind is from 240 degrees true at 15 knots, gusting to 25 knots.
In a METAR wind group, the first three digits are the direction in degrees true, the next two are the sustained speed in knots, and the value after "G" is the gust speed. So "24015G25KT" is 240 degrees at 15 knots gusting to 25 knots.
- What is density altitude, and why does it matter to a small UAS operator?
- It is pressure altitude corrected for nonstandard temperature; high density altitude reduces rotor/propeller efficiency and degrades performance.
- It is the height of the densest cloud layer; it determines legal ceiling.
- It is the altitude at which air becomes too thin to register on a barometer; it is irrelevant to sUAS.
Correct answer: It is pressure altitude corrected for nonstandard temperature; high density altitude reduces rotor/propeller efficiency and degrades performance.
Density altitude is pressure altitude corrected for nonstandard temperature. High temperature, high altitude, and high humidity raise density altitude, thinning the air so propellers produce less thrust and battery-powered aircraft perform worse.
- Which combination of conditions produces the HIGHEST density altitude, degrading sUAS performance the most?
- High air temperature, high field elevation, and high humidity.
- Low air temperature, low field elevation, and low humidity.
- Low temperature, high pressure, and dry air.
Correct answer: High air temperature, high field elevation, and high humidity.
Density altitude increases with rising temperature, elevation, and humidity. All three being high yields the thinnest air and the worst performance for propeller-driven and battery-powered aircraft.
- A TAF contains the group "FM1500 27012KT P6SM SCT040." What does "P6SM" indicate?
- Visibility is forecast to be greater than 6 statute miles.
- Visibility is forecast to be precisely 6 statute miles with precipitation.
- There is a probability of 6 statute miles of fog.
Correct answer: Visibility is forecast to be greater than 6 statute miles.
In aviation forecasts and reports, "P6SM" means visibility is greater than (Plus) 6 statute miles. The "FM1500" indicates the conditions begin at 1500 Zulu.
- What atmospheric stability condition is most associated with the formation of fog and poor visibility near the surface?
- A stable atmosphere, which limits vertical mixing and traps moisture near the surface.
- An unstable atmosphere, which encourages strong vertical currents and clears moisture.
- A neutrally stable atmosphere with strong surface heating.
Correct answer: A stable atmosphere, which limits vertical mixing and traps moisture near the surface.
Stable air resists vertical motion, allowing moisture, haze, and fog to accumulate near the surface and reducing visibility. Unstable air promotes mixing, cumulus development, and generally better visibility but more turbulence.
- What is the relationship between temperature and dew point that signals fog or low clouds are likely to form?
- When the temperature and dew point are close together (a small spread), the air is near saturation and fog or low clouds are likely.
- When the temperature is much higher than the dew point, fog is imminent.
- When the dew point exceeds the temperature by 10 degrees, visibility improves.
Correct answer: When the temperature and dew point are close together (a small spread), the air is near saturation and fog or low clouds are likely.
A small temperature/dew point spread means the air is close to saturation. As the spread narrows toward zero, relative humidity approaches 100% and fog or low stratus clouds become likely.
- Which official source is the most appropriate for a remote pilot to obtain a comprehensive preflight weather briefing?
- Aviation Weather Center products and an FAA-recognized briefing source such as 1800wxbrief.com.
- A consumer smartphone weather app showing the city forecast.
- A local television evening weather segment.
Correct answer: Aviation Weather Center products and an FAA-recognized briefing source such as 1800wxbrief.com.
Aviation-specific sources such as the Aviation Weather Center (aviationweather.gov) and Flight Service (1800wxbrief.com) provide METARs, TAFs, AIRMETs, SIGMETs, and TFR information relevant to flight, unlike consumer apps.
- A METAR reports "OVC008." If a remote pilot intends to operate at 200 ft AGL, why is the cloud clearance requirement still important to evaluate?
- Part 107 requires staying at least 500 ft below clouds; an 800 ft AGL overcast leaves only limited vertical clearance, and the pilot must remain below 300 ft AGL to comply.
- Overcast at 800 ft AGL prohibits all sUAS flight regardless of altitude.
- Cloud clearance does not apply to sUAS operations below 400 ft AGL.
Correct answer: Part 107 requires staying at least 500 ft below clouds; an 800 ft AGL overcast leaves only limited vertical clearance, and the pilot must remain below 300 ft AGL to comply.
"OVC008" means an overcast ceiling at 800 ft AGL. Per 14 CFR 107.51, the sUAS must remain at least 500 ft below clouds, so the pilot would need to stay at or below 300 ft AGL. A 200 ft AGL flight complies, but the clearance must be evaluated.
- How does a strong, gusty wind most directly threaten a small multirotor UAS operation?
- It can exceed the aircraft's ability to hold position, drain the battery faster as motors work harder, and make precise VLOS control difficult.
- It increases air density, improving performance but reducing range.
- It has no effect because multirotors automatically compensate for any wind speed.
Correct answer: It can exceed the aircraft's ability to hold position, drain the battery faster as motors work harder, and make precise VLOS control difficult.
Gusty winds force the flight controller and motors to work harder to maintain position, accelerating battery drain and increasing the risk of flyaway or loss of control, especially if winds approach or exceed the aircraft's maximum rated wind tolerance.
- Which of the five hazardous attitudes is best countered by the antidote "Follow the rules; they are usually right"?
- Anti-authority.
- Impulsivity.
- Invulnerability.
Correct answer: Anti-authority.
The anti-authority attitude ("Don't tell me") is countered by the antidote "Follow the rules. They are usually right." The five hazardous attitudes are anti-authority, impulsivity, invulnerability, macho, and resignation.
- A remote pilot thinks, "It won't happen to me," while skipping a preflight inspection. Which hazardous attitude is this and what is its antidote?
- Invulnerability; the antidote is "It could happen to me."
- Macho; the antidote is "Taking chances is foolish."
- Resignation; the antidote is "I'm not helpless."
Correct answer: Invulnerability; the antidote is "It could happen to me."
Believing accidents only happen to others reflects the invulnerability attitude, whose antidote is "It could happen to me." Recognizing personal risk encourages thorough preflight checks.
- What does the "DECIDE" model or aeronautical decision-making (ADM) primarily help a remote pilot do?
- Systematically detect a change, evaluate the situation, choose a course of action, and assess the outcome to manage risk.
- Calculate density altitude and center of gravity automatically.
- Memorize all Part 107 regulations verbatim.
Correct answer: Systematically detect a change, evaluate the situation, choose a course of action, and assess the outcome to manage risk.
Aeronautical decision-making provides a structured process to recognize hazards, evaluate options, act, and review results, reducing the chance of poor judgment leading to an incident.
- During flight the control link to the sUAS is lost. What is the most appropriate first response for a well-prepared remote pilot?
- Allow the aircraft to execute its preprogrammed lost-link procedure (such as return-to-home) while keeping the area clear of people.
- Immediately walk away from the control station to find help.
- Power off the controller entirely to force an immediate landing.
Correct answer: Allow the aircraft to execute its preprogrammed lost-link procedure (such as return-to-home) while keeping the area clear of people.
A prepared pilot knows the aircraft's lost-link behavior (often return-to-home or hover-then-land) and ensures the flight path and landing area are clear of people. Understanding and planning for emergencies is part of sound risk management.
- How does fatigue most directly degrade a remote pilot's performance?
- It slows reaction time, impairs judgment, and reduces the ability to maintain situational awareness and VLOS.
- It improves focus by triggering an adrenaline response.
- It only affects physical strength and has no effect on decision-making.
Correct answer: It slows reaction time, impairs judgment, and reduces the ability to maintain situational awareness and VLOS.
Fatigue diminishes attention, reaction time, and decision quality. A fatigued pilot is more likely to lose situational awareness or visual line of sight, increasing operational risk.
- When scanning the sky to keep an unmanned aircraft in sight, why is it sometimes effective to look slightly to the side of a distant object rather than directly at it in very low light?
- In low light the eye's peripheral rod cells are more sensitive, so off-center viewing can detect dim objects the central vision misses.
- The central cone cells work best in darkness, so looking away rests them.
- Off-center viewing eliminates the need for anti-collision lighting at night.
Correct answer: In low light the eye's peripheral rod cells are more sensitive, so off-center viewing can detect dim objects the central vision misses.
The rods responsible for night vision are concentrated outside the central fovea, so off-center (peripheral) scanning improves detection of dim objects in darkness. This does not replace required anti-collision lighting for night operations.
- A remote pilot under significant time pressure decides to launch without checking for a TFR, reasoning, "Do something quickly!" Which hazardous attitude is this and its antidote?
- Impulsivity; the antidote is "Not so fast. Think first."
- Anti-authority; the antidote is "Follow the rules."
- Resignation; the antidote is "I'm not helpless."
Correct answer: Impulsivity; the antidote is "Not so fast. Think first."
Acting on the first impulse without analysis reflects impulsivity, whose antidote is "Not so fast. Think first." Taking time to check airspace and TFRs prevents avoidable violations.
- What is the primary purpose of Crew Resource Management (CRM) in a multi-person sUAS operation?
- To effectively use all available human and equipment resources, including a visual observer, to improve safety and decision-making.
- To allow the visual observer to take legal responsibility for the flight from the RPIC.
- To eliminate the need for the RPIC to maintain visual line of sight.
Correct answer: To effectively use all available human and equipment resources, including a visual observer, to improve safety and decision-making.
CRM is the coordinated use of all available resources, including crew members and equipment, to make sound decisions. A visual observer can extend awareness, but the RPIC retains responsibility for the operation.
- Why should a remote pilot avoid operating while taking a sedating over-the-counter medication such as certain antihistamines?
- Such medications can cause drowsiness and slowed reaction time, impairing the judgment and alertness needed to operate safely.
- Antihistamines increase visual acuity, leading to overconfidence.
- They are explicitly required before any night operation.
Correct answer: Such medications can cause drowsiness and slowed reaction time, impairing the judgment and alertness needed to operate safely.
Sedating medications degrade alertness, reaction time, and judgment. A remote pilot must not operate when a physical or mental condition, including medication side effects, would interfere with safe operation (14 CFR 107.17).
- A remote pilot notices unusual vibration and a frayed propeller during preflight. Applying sound maintenance judgment, what should the pilot do?
- Ground the aircraft and replace or repair the propeller before flight.
- Fly a short test mission to confirm whether the propeller fails.
- Reduce throttle limits in software and proceed with the planned flight.
Correct answer: Ground the aircraft and replace or repair the propeller before flight.
A damaged propeller can fail in flight and cause loss of control. Good maintenance judgment requires correcting the discrepancy before flight; the RPIC must ensure the aircraft is in a condition for safe operation under 14 CFR 107.15.
- How can task saturation reduce a remote pilot's situational awareness during a complex operation?
- When too many tasks compete for attention, the pilot may fixate on one and lose track of the aircraft, airspace, or surroundings.
- Task saturation always improves awareness by keeping the pilot engaged.
- It only affects the visual observer, never the RPIC.
Correct answer: When too many tasks compete for attention, the pilot may fixate on one and lose track of the aircraft, airspace, or surroundings.
Task saturation overloads the pilot's capacity, causing fixation or omission of important checks. Prioritizing, delegating to a visual observer, and managing workload help preserve situational awareness.
- A remote pilot facing a deteriorating situation thinks, "What's the use? It's out of my hands now." Which hazardous attitude is this and what is its antidote?
- Resignation; the antidote is "I'm not helpless. I can make a difference."
- Macho; the antidote is "Taking chances is foolish."
- Invulnerability; the antidote is "It could happen to me."
Correct answer: Resignation; the antidote is "I'm not helpless. I can make a difference."
Feeling powerless and leaving outcomes to luck reflects the resignation attitude, whose antidote is "I'm not helpless. I can make a difference." Recognizing one's ability to influence the outcome restores active risk management.
- What is the maximum total weight of a small unmanned aircraft system permitted to operate under Part 107?
- Less than 55 pounds, including payload and everything onboard at takeoff.
- Less than 25 pounds, excluding the battery.
- Less than 100 pounds, including the control station.
Correct answer: Less than 55 pounds, including payload and everything onboard at takeoff.
Part 107 applies to small UAS weighing less than 55 pounds total at takeoff, including payload (14 CFR 107.3). Adding payload reduces remaining capacity and affects performance.
- How does adding payload that shifts the center of gravity (CG) outside the manufacturer's limits typically affect a multirotor sUAS?
- It can make the aircraft harder to stabilize and control, increasing the risk of erratic flight or loss of control.
- It always improves stability by lowering the center of gravity.
- It has no effect because flight controllers compensate for any CG location.
Correct answer: It can make the aircraft harder to stabilize and control, increasing the risk of erratic flight or loss of control.
An out-of-limits CG forces the flight controller to work harder to maintain level, stable flight and can exceed its compensation range, leading to control difficulties or loss of control. Loads should be balanced within the manufacturer's specifications.
- On a hot, high-elevation day, how does a heavier payload combined with high density altitude affect a battery-powered sUAS?
- The aircraft must work harder to generate lift in thinner air, reducing flight time, climb performance, and available margin.
- Performance improves because heavier loads stabilize the aircraft in thin air.
- Battery life increases because cooler high-altitude air offsets the load.
Correct answer: The aircraft must work harder to generate lift in thinner air, reducing flight time, climb performance, and available margin.
High density altitude thins the air so propellers produce less thrust, while a heavier payload demands more power. Together they shorten flight time and degrade climb and maneuvering performance, leaving less safety margin.
- Why is it important to verify a remaining battery margin before continuing a flight rather than flying until the battery is nearly empty?
- Voltage can drop sharply under load and in cold or high-demand conditions, so a reserve margin prevents power loss before a safe landing.
- Batteries gain capacity as they discharge, so a low reading is misleading.
- Reserve battery is only required during night operations.
Correct answer: Voltage can drop sharply under load and in cold or high-demand conditions, so a reserve margin prevents power loss before a safe landing.
Battery voltage sags under load and falls faster in cold weather or high-demand maneuvers. Maintaining a planned reserve ensures enough power to land safely and reduces the risk of an in-flight power loss or flyaway.
- Under Part 107, within how many days must a remote pilot report an accident to the FAA if it results in serious injury or property damage of more than $500 (other than to the sUAS itself)?
- Within 10 calendar days.
- Within 24 hours.
- Within 30 calendar days.
Correct answer: Within 10 calendar days.
Per 14 CFR 107.9, a remote pilot must report to the FAA within 10 calendar days any operation that results in serious injury, loss of consciousness, or property damage of at least $500 (excluding damage to the sUAS).
- What are the requirements for registering a small unmanned aircraft used under Part 107, and how must the registration be displayed?
- Every drone flown under Part 107 must be registered regardless of weight, and the registration number must be marked on an external surface of the aircraft.
- Only aircraft over 25 lb require registration, and the number may be kept indoors.
- Registration is optional for commercial operations, and no marking is required.
Correct answer: Every drone flown under Part 107 must be registered regardless of weight, and the registration number must be marked on an external surface of the aircraft.
Any small UAS operated under Part 107 must be registered with the FAA regardless of weight (the 0.55 lb / 250 g threshold applies only to recreational flyers). The unique registration number must be legibly displayed on an exterior surface of the aircraft (14 CFR Part 48). Registration costs $5 and is valid for 3 years.
- A remote pilot wants to fly beyond visual line of sight, which Part 107 normally prohibits. What is the correct way to legally conduct such an operation?
- Apply for and obtain a Certificate of Waiver from the FAA demonstrating the operation can be conducted safely.
- Simply log the operation and notify the nearest control tower beforehand.
- Operate it as long as a second drone relays the video feed, with no FAA approval.
Correct answer: Apply for and obtain a Certificate of Waiver from the FAA demonstrating the operation can be conducted safely.
Certain Part 107 limitations, including the VLOS requirement, may be waived under 14 CFR 107.200 if the applicant shows the FAA the operation can be performed safely. The FAA may issue a Certificate of Waiver with conditions.
- What are the minimum eligibility requirements to obtain a Remote Pilot Certificate with a small UAS rating?
- Be at least 16 years old, able to read/speak/write/understand English, pass the aeronautical knowledge test, and be vetted by the TSA.
- Be at least 18 years old, hold a private pilot certificate, and pass a medical exam.
