FAA Part 107 Remote Pilot Knowledge Test — Questions and Answers

Question 1: If a new payload is added to an sUAS, what must the Remote PIC do before flight?

Recalculate weight and balance to ensure it is within limits. (Correct answer)
Notify the FAA of the modification.
Fly a brief test flight in a congested area.
Assume the flight characteristics will not change.

Correct answer: Recalculate weight and balance to ensure it is within limits.

Any change to the aircraft's loading, such as adding a new camera or sensor, requires the Remote PIC to verify that the total weight and the new center of gravity are within the manufacturer's specified limits. This is a critical preflight action.

Question 2: What is the standard direction for turns in a traffic pattern at an airport?

Left turns (Correct answer)
Turns toward the airport
Right turns
Turns away from the airport

Correct answer: Left turns

Unless otherwise specified, all turns in an airport traffic pattern are made to the left. Any right-hand patterns will be explicitly noted in the Chart Supplement or on the sectional chart.

Question 3: An sUAS is loaded with its center of gravity (CG) at the most aft limit. What flight characteristic should the remote pilot expect?

The sUAS will be unstable and difficult to recover from a stall. (Correct answer)
The sUAS will be less maneuverable.
The sUAS will require less power for level flight.
The sUAS will be excessively stable.

Correct answer: The sUAS will be unstable and difficult to recover from a stall.

An aft CG reduces longitudinal stability, making the aircraft tail-heavy and twitchy in the pitch axis. This instability makes it very difficult to recover from a stall, as the aircraft may not have enough elevator authority to lower the nose.

Question 4: What happens to a remote pilot's Part 107 privileges if they fail to complete recurrent training within 24 calendar months?

They must apply for an entirely new certificate
They must retake the initial knowledge test at a testing center
Their certificate is automatically revoked
Their privilege to act as remote PIC lapses until training is completed (Correct answer)

Correct answer: Their privilege to act as remote PIC lapses until training is completed

If recurrent training is not completed within 24 months, the remote pilot's privileges lapse and they cannot legally act as remote PIC until training is finished.

Question 5: Which of the following is a common human factor that can lead to accidents in unmanned aircraft operations?

Fatigue and stress (Correct answer)
Well-maintained equipment
Advanced navigation systems
Crew resource management

Correct answer: Fatigue and stress

Fatigue and stress are common human factors that can significantly impair a remote pilot's judgment, reaction time, and decision-making abilities, thereby increasing the risk of accidents in unmanned aircraft operations. These conditions can lead to reduced situational awareness, errors in control inputs, and poor risk assessment. Recognizing and mitigating these factors is crucial for safe UAS operations.

Question 6: For the purposes of Part 107, "night" is defined as the time between:

30 minutes after sunset to 30 minutes before sunrise.
Sunset and sunrise.
10:00 PM and 6:00 AM local time.
The end of evening civil twilight and the beginning of morning civil twilight. (Correct answer)

Correct answer: The end of evening civil twilight and the beginning of morning civil twilight.

Part 107 defines night as the time from the end of evening civil twilight to the beginning of morning civil twilight, as published in the Air Almanac. This is a more precise definition than simply sunset to sunrise.

Question 7: Which combination of conditions would lead to the highest density altitude?

High altitude, high temperature, and high humidity. (Correct answer)
High altitude, low temperature, and low humidity.
Low altitude, low temperature, and low humidity.
Low altitude, high temperature, and low humidity.

Correct answer: High altitude, high temperature, and high humidity.

Density altitude increases with higher elevation, higher temperatures, and higher humidity. Therefore, a hot, humid day at a high-elevation airport will produce the highest density altitude and the worst aircraft performance.

Question 8: How do thermal updrafts and convective activity during midday hours affect sUAS flight stability?

Convective activity only affects operations above 1,000 feet AGL
Thermal activity has no measurable effect on sUAS below 55 lbs
Thermal updrafts create localized vertical air movement and turbulence that can cause unpredictable attitude changes (Correct answer)
Thermals improve sUAS stability by providing consistent upward lift

Correct answer: Thermal updrafts create localized vertical air movement and turbulence that can cause unpredictable attitude changes

Surface heating creates localized columns of rising warm air (thermals) surrounded by cooler descending air, generating pockets of turbulence and vertical air movement that can destabilize an sUAS.

Question 9: In the airport data block on a sectional chart, what does the letter "L" next to the runway length indicate?

The airport is a Left-hand traffic pattern airport.
The airport has lighting available. (Correct answer)
The runway is less than 8,069 feet long.
The airport has low-intensity runway lighting.

Correct answer: The airport has lighting available.

The "L" in the airport data block indicates that the airport has lighting facilities. An asterisk (*) next to the "L" signifies that the lighting operates on a limited schedule or requires pilot activation.

Question 10: What minimum passing score is required on the Part 107 initial aeronautical knowledge test?

90%
75%
80%
70% (Correct answer)

Correct answer: 70%

An applicant must achieve a score of at least 70% on the Part 107 aeronautical knowledge test to pass and qualify for the certificate.

Question 11: A temperature inversion can create a hazard for sUAS operations primarily because it can lead to:

Increased air density and better performance.
Significant wind shear and poor visibility. (Correct answer)
Decreased propeller efficiency regardless of altitude.
The rapid formation of cumulonimbus clouds.

Correct answer: Significant wind shear and poor visibility.

A temperature inversion creates a very stable layer of air that can trap smoke, dust, and other pollutants, leading to very poor visibility. It can also be a source of significant low-level wind shear.

Question 12: When operating a drone near an airport without an operating control tower, which frequency should the remote pilot use to monitor local traffic?

UNICOM (122.8)
The designated CTAF frequency (Correct answer)
MULTICOM (122.9)
The local AWOS frequency

Correct answer: The designated CTAF frequency

The Common Traffic Advisory Frequency (CTAF) is designated for carrying out airport advisory practices while operating to or from an airport without an operating control tower. This frequency is listed in the Chart Supplement and on the sectional chart.

Question 13: How can a strong tailwind affect an sUAS during high-speed forward flight?

A strong tailwind reduces relative airspeed over the rotors, decreasing control effectiveness and lift efficiency (Correct answer)
Tailwinds have no aerodynamic effect on multirotor sUAS
A tailwind always improves performance by adding to ground speed
Tailwinds cool the motors by increasing airflow, improving overall efficiency

Correct answer: A strong tailwind reduces relative airspeed over the rotors, decreasing control effectiveness and lift efficiency

Rotor lift and control authority depend on relative airspeed — a strong tailwind reduces the relative wind over the rotors, degrading lift efficiency and pitch/roll control response.

Question 14: A key distinction between Category 2 and Category 3 operations over people is that...

Category 3 drones can be flown over open-air assemblies, but Category 2 drones cannot.
Category 3 drones must not have any exposed rotating parts that could cause skin lacerations. (Correct answer)
Category 2 drones must have a remote pilot with an advanced rating.
Category 2 drones can operate at night, but Category 3 drones cannot.

Correct answer: Category 3 drones must not have any exposed rotating parts that could cause skin lacerations.

Both Category 2 and Category 3 are based on impact kinetic energy limits, with Category 3 allowing for a higher impact energy. However, a critical safety requirement for Category 3 is that the drone must be designed to prevent lacerations from exposed rotating parts, a requirement not explicitly placed on Category 2 drones.

Question 15: What is 'pitch' as it relates to sUAS propeller blades?

The total diameter of the propeller arc
The weight distribution along the length of the blade
The theoretical distance a propeller would advance through the air in one complete revolution (Correct answer)
The rotational speed of the motor in RPM

Correct answer: The theoretical distance a propeller would advance through the air in one complete revolution

Pitch is the theoretical forward distance a propeller travels per revolution based on blade angle — a higher pitch moves more air per revolution but demands more torque from the motor.

Question 16: Which statement is true regarding the use of vision aids for night drone operations?

The remote pilot must not use any vision aids, relying only on unaided vision.
Sunglasses with yellow lenses are recommended to enhance contrast.
Night vision goggles (NVGs) are required for all Part 107 night flights.
The remote pilot must be able to see the drone with their own natural vision, without the aid of NVGs. (Correct answer)

Correct answer: The remote pilot must be able to see the drone with their own natural vision, without the aid of NVGs.

While vision aids like binoculars can be used momentarily to scan the airspace, the remote pilot must maintain visual line of sight (VLOS) with the drone using their own natural, unassisted vision. Night vision goggles cannot be used as the primary means of maintaining VLOS.

Question 17: The term 'arm' in weight and balance calculations refers to the:

The product of weight and distance.
Horizontal distance from the reference datum. (Correct answer)
The maximum weight an item can be.
Total weight of the aircraft.

Correct answer: Horizontal distance from the reference datum.

In weight and balance terminology, the 'arm' is the horizontal distance from the reference datum to the center of gravity of an item. The 'moment' is then calculated by multiplying the weight of the item by its arm.

Question 18: In a METAR, what does the code `VC` indicate?

Violent Clouds.
Variable Ceiling.
In the Vicinity. (Correct answer)
Visual Conditions.

Correct answer: In the Vicinity.

The code `VC` stands for 'Vicinity,' which means the specified weather phenomenon is not at the airport station itself, but is within 5 to 10 statute miles of the station. For example, `VCSH` means showers in the vicinity.

Question 19: What does 'visual line of sight' (VLOS) require of the remote pilot under Part 107?

A visual observer maintains sight of the sUAS on behalf of the pilot
The remote pilot can see the sUAS with unaided vision at all times (Correct answer)
The remote pilot may use binoculars to track the sUAS
A first-person view camera provides adequate situational awareness

Correct answer: The remote pilot can see the sUAS with unaided vision at all times

VLOS requires the remote pilot to see the sUAS at all times using only natural unaided vision, without optical aids such as binoculars.

Question 20: What does a small magenta flag symbol on a sectional chart indicate?

A designated parachute jumping area.
A location of an ultralight flight park.
A prominent visual checkpoint for VFR navigation. (Correct answer)
A military training route.

Correct answer: A prominent visual checkpoint for VFR navigation.

A magenta flag on a sectional chart marks a VFR (Visual Flight Rules) checkpoint. These are prominent geographical features that can be used by pilots to visually identify their position.

Question 21: Which of the following is an appropriate self-announcement on the CTAF for a drone operation?

Drone one, taking off now.
Mayday, mayday, drone in the pattern.
Manned aircraft, be advised of drone activity.
Springfield Traffic, drone operation, 2 miles northwest of the airport at 300 feet, Springfield Traffic. (Correct answer)

Correct answer: Springfield Traffic, drone operation, 2 miles northwest of the airport at 300 feet, Springfield Traffic.

A proper CTAF call includes the name of the airport you are near, your aircraft type (drone/UAS), your location relative to the airport, your altitude, and ends with the airport name again. This provides clear and concise information to other pilots.

Question 22: How does operating in hot, humid summer conditions affect sUAS endurance compared to cool, dry conditions?

Temperature and humidity only affect fixed-wing aircraft endurance, not multirotors
Endurance improves in hot conditions because lithium batteries perform better at higher temperatures
Hot, humid conditions reduce endurance because lower air density requires higher RPMs for the same lift (Correct answer)
Hot, humid conditions improve endurance because warm air provides more lift

Correct answer: Hot, humid conditions reduce endurance because lower air density requires higher RPMs for the same lift

High temperature and humidity reduce air density (increase density altitude), requiring motors to spin faster and consume more power per minute, shortening total flight time.

Question 23: What is the primary reason a remote pilot should allow their eyes 30 minutes to adapt to the darkness before a night flight?

To reduce the risk of temporary blindness from the controller screen.
To comply with a specific FAA mandate on pre-flight preparation time.
To ensure the drone's anti-collision lights appear brighter.
To improve night vision by allowing the rods in the eyes to become more sensitive to low light. (Correct answer)

Correct answer: To improve night vision by allowing the rods in the eyes to become more sensitive to low light.

The human eye uses two types of cells: cones for color and detail in bright light, and rods for vision in low light. It takes approximately 30 minutes for the rods to reach their maximum sensitivity, a process called dark adaptation, which is crucial for effective night vision.

Question 24: In the event of a near-miss with a manned aircraft, what action should a Remote Pilot take?

File a report with the National Transportation Safety Board (NTSB)
Ignore the incident if no damage occurred
Only report if instructed by an FAA official
Report the incident to the FAA as soon as possible (Correct answer)

Correct answer: Report the incident to the FAA as soon as possible

In the event of a near-miss with a manned aircraft, the Remote Pilot should report the incident to the FAA as soon as possible. While specific reporting criteria exist for serious injury or significant property damage, any incident involving a near-miss with manned aircraft is a serious safety concern that warrants immediate attention. Prompt reporting allows the FAA to investigate, identify potential risks, and implement measures to prevent future occurrences, thereby enhancing overall airspace safety.

Question 25: The acronym CTAF stands for:

Common Tower Advisory Frequency
Common Traffic Advisory Frequency (Correct answer)
Central Terminal Area Frequency
Control Tower Air Frequency

Correct answer: Common Traffic Advisory Frequency

CTAF stands for Common Traffic Advisory Frequency. It is the frequency used by pilots to communicate their positions and intentions near non-towered airports.

Question 26: What effect does high density altitude have on sUAS rotor performance?

High density altitude only affects fixed-wing aircraft, not multirotors
Rotors generate the same lift regardless of density altitude
Rotor efficiency decreases because less dense air generates less lift per revolution (Correct answer)
Rotor efficiency increases due to lower air resistance

Correct answer: Rotor efficiency decreases because less dense air generates less lift per revolution

Thinner air at high density altitude means each rotor revolution moves less air mass, reducing lift and requiring higher RPMs to maintain hover.

Question 27: What is the recommended procedure for entering an airport traffic pattern?

Cross over the airport at 500 feet above pattern altitude and join the downwind leg.
Enter directly onto the final approach leg.
Enter on the downwind leg at a 90-degree angle.
Enter at a 45-degree angle to the downwind leg, at traffic pattern altitude. (Correct answer)

Correct answer: Enter at a 45-degree angle to the downwind leg, at traffic pattern altitude.

The standard recommended entry procedure is to enter the pattern on a 45-degree angle to the downwind leg, heading toward a point abeam the midpoint of the runway. This allows the pilot to see and be seen by other aircraft in the pattern.

Question 28: Under the rules for Operations Over Moving Vehicles, a remote pilot is generally prohibited from...

briefly crossing over a road with moving cars.
maintaining sustained flight over a moving vehicle. (Correct answer)
operating within a closed-access site over company vehicles.
flying a Category 1 drone over a moving vehicle.

Correct answer: maintaining sustained flight over a moving vehicle.

While transient flight over moving vehicles is permitted for certain categories of drones, sustained flight is not. Sustained flight includes hovering over, flying back and forth over, or circling the same moving vehicle, which poses a greater risk.

Question 29: What is 'vortex ring state' in the context of multirotor sUAS operations?

Vortices formed at propeller tips that improve efficiency
The normal circular airflow pattern around propellers during cruise
A favorable aerodynamic state that reduces power during descent
A dangerous condition where the aircraft descends into its own rotor downwash, causing loss of lift (Correct answer)

Correct answer: A dangerous condition where the aircraft descends into its own rotor downwash, causing loss of lift

Vortex ring state occurs during a steep, slow powered descent when rotor downwash recirculates back into the rotor disc, causing the rotor to lose lift in a potentially unrecoverable condition.

Question 30: Who is primarily responsible for ensuring an sUAS is loaded correctly and operated within weight and balance limitations?

The sUAS manufacturer.
The Federal Aviation Administration (FAA).
The owner of the sUAS.
The Remote Pilot in Command (PIC). (Correct answer)

Correct answer: The Remote Pilot in Command (PIC).

According to 14 CFR Part 107, the Remote Pilot in Command (PIC) is directly responsible for, and is the final authority on, the safe operation of the sUAS. This includes preflight checks of loading, weight, and balance.

Question 31: Which component is crucial for determining the location, altitude, and direction of the sUAS?

The GPS system (Correct answer)
The camera
The propeller
The battery

Correct answer: The GPS system

The GPS (Global Positioning System) is a vital component for sUAS navigation. It provides precise data regarding the aircraft's current location (latitude, longitude), altitude, and direction of travel. This information is essential for stable flight, autonomous operations, waypoint navigation, and critical safety features like Return-to-Home (RTH).

Question 32: How often must a remote pilot complete recurrent training to maintain Part 107 privileges?

Every 36 calendar months
Every 24 calendar months (Correct answer)
Every 6 calendar months
Every 12 calendar months

Correct answer: Every 24 calendar months

Part 107 requires remote pilots to complete a recurrent online training course every 24 calendar months to maintain their operating privileges.

Question 33: Which weather product is a report of current surface weather observations, rather than a forecast?

TAF (Terminal Aerodrome Forecast).
METAR (Aviation Routine Weather Report). (Correct answer)
GFA (Graphical Forecasts for Aviation).
PIREP (Pilot Report).

Correct answer: METAR (Aviation Routine Weather Report).

A METAR is a routine weather report that provides current surface weather conditions observed at a specific time and location (an airport). A TAF, in contrast, is a forecast of expected weather conditions.

Question 34: What is 'ground effect' as it applies to multirotor sUAS operations?

Increased rotor efficiency caused by reduced induced drag when flying close to the ground (Correct answer)
Reduced battery consumption due to lower altitude air pressure
Turbulence created by flying close to the surface
Vibration felt by the aircraft when landing on uneven terrain

Correct answer: Increased rotor efficiency caused by reduced induced drag when flying close to the ground

Ground effect occurs when rotor downwash is interrupted by the ground surface, reducing induced drag and increasing lift efficiency within approximately one rotor diameter of the surface.

Question 35: (Refer to METAR: KXYZ 121853Z AUTO 18015G25KT 3SM -RA BKN008 OVC012 13/12 A2992) What is the reported ceiling?

800 feet AGL. (Correct answer)
There is no ceiling reported.
1,200 feet AGL.
3 statute miles.

Correct answer: 800 feet AGL.

A ceiling is defined as the height of the lowest layer of clouds reported as broken (BKN) or overcast (OVC). In this METAR, the lowest such layer is `BKN008`, which corresponds to a ceiling at 800 feet AGL.

Question 36: How is a private airport depicted on a sectional chart?

As a solid blue circle.
As a blue circle with an "R" inside.
As a magenta circle with an "R" inside. (Correct answer)
As an open magenta circle with the letter "Pvt" next to the airport name.

Correct answer: As a magenta circle with an "R" inside.

A private airport is shown as a circle with an "R" in the middle, depicted in magenta. The "R" signifies that it is a restricted or private airport, and prior permission is required for use.

Question 37: The valid period of a routine Terminal Aerodrome Forecast (TAF) is typically:

48 hours.
12 hours.
24 hours. (Correct answer)
6 hours.

Correct answer: 24 hours.

Standard TAFs are issued four times a day at 0000Z, 0600Z, 1200Z, and 1800Z. They are typically valid for a 24-hour period, though some international locations may have 30-hour TAFs.

Question 38: What aerodynamic principle allows a multirotor sUAS to accelerate into forward flight from a hover?

Increased motor speed creates a low-pressure zone that pulls the aircraft forward
Tilting the aircraft forward converts a portion of rotor thrust from vertical lift into horizontal propulsion (Correct answer)
The landing gear extends to create a rearward aerodynamic drag surface
Differential thrust between front and rear rotors pushes air backward

Correct answer: Tilting the aircraft forward converts a portion of rotor thrust from vertical lift into horizontal propulsion

By pitching nose-down, the total thrust vector tilts forward — dividing into a vertical component (lift) and a horizontal component (forward thrust) to produce acceleration.

Question 39: Before a remote pilot can conduct night operations, what must they do?

Complete an initial aeronautical knowledge test or recurrent training covering night operations. (Correct answer)
Log at least 3 hours of night flight time in a simulator.
Obtain a specific night operations waiver from the FAA.
Equip the drone with infrared cameras.

Correct answer: Complete an initial aeronautical knowledge test or recurrent training covering night operations.

The FAA updated the rules to allow night operations without a waiver, provided the remote pilot completes an updated initial knowledge test or the recurrent online training that covers topics related to night operations. This ensures the pilot is knowledgeable about night-specific risks and procedures.

Question 40: What is the primary danger associated with thunderstorms for an sUAS?

Extreme turbulence and wind shear. (Correct answer)
Low ceilings and poor visibility.
High density altitude.
Radio frequency interference.

Correct answer: Extreme turbulence and wind shear.

While all listed options are hazards, the most significant and immediate danger from thunderstorms is the extreme turbulence and wind shear associated with updrafts, downdrafts (microbursts), and gust fronts. These can easily cause a loss of control.

Question 41: What is a potential effect of operating an sUAS above its maximum gross weight?

Improved maneuverability.
Lower stalling speed.
Reduced maneuverability and endurance. (Correct answer)
Increased flight time.

Correct answer: Reduced maneuverability and endurance.

Operating an aircraft above its maximum gross weight requires more power to generate the necessary lift, which significantly reduces flight time and endurance. The increased mass also makes the aircraft less responsive to control inputs.

Question 42: For night operations, the anti-collision lights on a small unmanned aircraft must be visible for at least how many statute miles?

1 statute mile
3 statute miles (Correct answer)
5 statute miles
10 statute miles

Correct answer: 3 statute miles

According to 14 CFR Part 107, a small unmanned aircraft must have anti-collision lighting that is visible for at least 3 statute miles. The lights should have a flash rate sufficient to avoid a collision.

Question 43: At an airport with a UNICOM frequency, what is its primary purpose?

To provide air traffic control services.
To provide airport advisory information from a non-government, ground-based station. (Correct answer)
To communicate with military aircraft only.
To broadcast automated weather information.

Correct answer: To provide airport advisory information from a non-government, ground-based station.

UNICOM (Universal Communications) is a non-government air/ground communication station which may provide airport information, such as weather, wind direction, and recommended runway. It is an advisory service, not a control service.

Question 44: What is a primary requirement for a small UAS to be operated over people under Category 4?

It must have an airworthiness certificate issued under Part 21. (Correct answer)
It must be operated by a pilot with at least 100 hours of flight time.
It must be made entirely of frangible materials.
It must weigh less than 55 pounds and have a parachute system.

Correct answer: It must have an airworthiness certificate issued under Part 21.

Category 4 is for drones that do not meet the kinetic energy or weight limits of Categories 1, 2, or 3. To qualify, these drones must undergo a rigorous FAA certification process and receive an airworthiness certificate under Part 21, similar to manned aircraft.

Question 45: What minimum flight visibility is required for Part 107 sUAS operations?

2 statute miles
1 statute mile
3 statute miles (Correct answer)
5 statute miles

Correct answer: 3 statute miles

Part 107 requires a minimum flight visibility of 3 statute miles from the remote pilot's ground control station.

Question 46: What is a likely consequence of operating an sUAS with a center of gravity (CG) that is too far forward?

Lower cruising speed.
Decreased longitudinal stability.
Difficulty recovering from a spin.
Higher stalling speed. (Correct answer)

Correct answer: Higher stalling speed.

A forward CG makes the aircraft nose-heavy, which increases longitudinal stability. However, it requires more tail-down force to maintain level flight, which increases the total lift required from the wing and results in a higher stalling speed.

Question 47: How can remote pilots mitigate the effects of fatigue during flight operations?

By using autopilot systems continuously
By operating only in the early morning hours
By drinking caffeinated beverages
By scheduling regular rest breaks and ensuring adequate sleep before operations (Correct answer)

Correct answer: By scheduling regular rest breaks and ensuring adequate sleep before operations

Remote pilots can effectively mitigate the effects of fatigue by scheduling regular rest breaks during operations and ensuring they get adequate sleep before any flight activity. Proper rest allows the body and mind to recover, maintaining alertness, concentration, and good judgment. Avoiding prolonged periods of continuous operation and prioritizing sleep are key to safe piloting.

Question 48: What role does the flight controller's IMU (Inertial Measurement Unit) play in maintaining aerodynamic stability?

It measures acceleration and angular rates, enabling the flight controller to adjust individual rotor speeds to correct attitude deviations (Correct answer)
It adjusts rotor blade pitch to compensate for wind gusts
It controls the camera gimbal to compensate for aircraft movement
It measures air pressure to maintain a constant barometric altitude

Correct answer: It measures acceleration and angular rates, enabling the flight controller to adjust individual rotor speeds to correct attitude deviations

The IMU detects tiny changes in pitch, roll, and yaw many times per second, enabling the flight controller to make rapid rotor speed adjustments that keep the aircraft aerodynamically stable.

Question 49: Which combination of environmental conditions results in the highest density altitude?

High elevation, cold temperature, low humidity
High elevation, hot temperature, high humidity (Correct answer)
Low elevation, hot temperature, high humidity
Low elevation, cold temperature, high humidity

Correct answer: High elevation, hot temperature, high humidity

High elevation reduces pressure, hot temperatures reduce air density, and high humidity displaces denser oxygen molecules — all three factors combine to create maximum density altitude.

Question 50: A remote pilot flying at night may experience the autokinetic illusion, which is when a:

series of ground lights is mistaken for the runway.
bright light is mistaken for an aircraft on a collision course.
stationary light appears to move when stared at for a prolonged period. (Correct answer)
distant object is perceived as being closer than it actually is.

Correct answer: stationary light appears to move when stared at for a prolonged period.

The autokinetic illusion occurs when a static light source, such as a star or a drone's light, is stared at in the dark and appears to move or wander. Pilots must be aware of this illusion to avoid becoming disoriented or misjudging the drone's position.

Question 51: For the purpose of Part 107 operations over people, the flight is not considered to be 'over' people if...

the drone is at least 200 feet above the people.
the people have given their consent to be flown over.
the drone passes over them so quickly that it is not sustained. (Correct answer)
the people are wearing protective headwear.

Correct answer: the drone passes over them so quickly that it is not sustained.

The FAA clarifies that a brief, transient passage over a person is not the focus of the rule. The rule applies to sustained flight over people, such as hovering or circling. A drone that passes over a person for a brief moment is not considered to be operating 'over' them in the context of this rule.

Question 52: According to Part 107, which of these scenarios is permissible without a waiver?

Flying over your neighbor who is sunbathing in their backyard.
Flying over spectators at a high school football game.
Flying over a concert crowd to get an establishing shot.
Flying over people who are inside a stationary, covered vehicle. (Correct answer)

Correct answer: Flying over people who are inside a stationary, covered vehicle.

The regulations for operations over people do not apply if the people are located under a covered structure or inside a stationary vehicle that can provide reasonable protection from a falling drone. This is because the vehicle itself acts as a protective barrier.

Question 53: What should a Remote Pilot do if a sUAS experiences a loss of control link during flight?

Continue flying as best as possible
Attempt to re-establish the control link while flying
Follow the pre-programmed lost link procedures (Correct answer)
Immediately land the sUAS manually

Correct answer: Follow the pre-programmed lost link procedures

In the event of a loss of control link during flight, the Remote Pilot should immediately follow the sUAS's pre-programmed lost link procedures. These procedures are configured before flight and dictate how the drone should behave, such as initiating a return-to-home, hovering, or performing an automatic landing. Relying on these pre-planned actions ensures a predictable and safe response to a critical communication failure, minimizing risk.

Question 54: What are the characteristics of a stable air mass?

Smooth air, poor visibility, and stratiform clouds. (Correct answer)
Turbulent air, good visibility, and cumuliform clouds.
Showery precipitation, strong surface winds, and good visibility.
Thunderstorms, turbulence, and hail.

Correct answer: Smooth air, poor visibility, and stratiform clouds.

In a stable air mass, vertical air movement is resisted. This results in smooth air, poor visibility due to trapped haze and pollutants, and stratiform clouds with steady, continuous precipitation.

Question 55: What phenomenon commonly occurs when an sUAS performs a rapid deceleration (quick stop) from high-speed forward flight?

The aircraft experiences increased lift from the sudden airflow change over the rotors
The landing gear deploys automatically to prevent a hard landing
The motors automatically reduce power to avoid rotor over-speed
The aircraft pitches nose-high and may experience a momentary altitude loss before stabilizing (Correct answer)

Correct answer: The aircraft pitches nose-high and may experience a momentary altitude loss before stabilizing

During a quick-stop, inertia carries the aircraft forward while the rotor disc tilts rearward to brake — the nose pitches up, the vertical lift component decreases, and altitude drops momentarily.

Question 56: What effect does high density altitude have on the performance of a small unmanned aircraft?

Performance is decreased due to reduced propeller efficiency. (Correct answer)
Performance is not affected by density altitude.
Performance is only affected by the aircraft's weight.
Performance is increased due to less air resistance.

Correct answer: Performance is decreased due to reduced propeller efficiency.

High density altitude means the air is less dense. This reduces propeller efficiency, decreases lift, and diminishes engine power output, all of which lead to reduced overall performance.

Question 57: What is the maximum altitude at which you can legally operate a sUAS without special permission from the FAA?

300 feet AGL
500 feet AGL
200 feet AGL
400 feet AGL (Correct answer)

Correct answer: 400 feet AGL

Under FAA Part 107, the maximum altitude for operating a sUAS without special permission is 400 feet Above Ground Level (AGL). This regulation is in place to maintain safe separation from manned aircraft, which typically operate at higher altitudes. If operating within a 400-foot radius of a structure, the sUAS may fly up to 400 feet above the structure's uppermost limit.

Question 58: To operate a small UAS over people under Category 1, what two conditions must be met?

The drone must weigh 0.55 pounds or less and have no exposed rotating parts that could lacerate human skin. (Correct answer)
The drone must weigh 1.0 pound or less and have propeller guards.
The drone must have Remote ID and weigh less than 4.4 pounds.
The drone must be flown below 100 feet AGL and only over people involved in the operation.

Correct answer: The drone must weigh 0.55 pounds or less and have no exposed rotating parts that could lacerate human skin.

Category 1 operations have the least stringent requirements because the drones are very light. The drone must have a maximum takeoff weight of 0.55 pounds (250 grams) or less, and it must not contain any exposed rotating parts that could cut skin upon impact.

Question 59: What must a remote pilot provide to law enforcement who requests inspection during sUAS operations?

Only the FAA registration number on the aircraft

Question 60: How does increasing altitude above sea level affect the relationship between true airspeed and indicated airspeed?

Indicated airspeed is greater than true airspeed at higher altitudes
True airspeed is greater than indicated airspeed at higher altitudes (Correct answer)
True airspeed equals indicated airspeed at all altitudes
True airspeed decreases relative to indicated airspeed as altitude increases

Correct answer: True airspeed is greater than indicated airspeed at higher altitudes

At higher altitudes with less dense air, the aircraft must move faster (true airspeed) to achieve the same dynamic pressure reading (indicated airspeed) as at sea level.
