1. What is the primary federal regulation that governs commercial
drone operations in the United States?
a) Part 91
b) Part 61
c) Part 107
d) Part 135
Rationale: Part 107 of the Federal Aviation Administration (FAA)
regulations specifically governs commercial small unmanned aircraft
system (sUAS) operations, including licensing, operational limitations,
and pilot requirements.
2. When inspecting a drone, which component is most critical to
verify for safety before flight?
a) Camera quality
b) Propellers and motors
c) Remote controller model
d) Battery color
Rationale: Propellers and motors are critical for flight safety. Damage or
wear can cause loss of control, leading to crashes and potential injury.
3. How often should a drone battery be inspected for physical
damage and swelling?
a) Once per month
b) Before each flight
, c) Every 100 flight hours
d) Only if the drone shows performance issues
Rationale: Batteries should be inspected before every flight to prevent
mid-flight failures caused by physical damage, swelling, or other
defects.
4. What is the maximum altitude allowed for most Part 107 drone
operations without special authorization?
a) 200 feet
b) 400 feet
c) 600 feet
d) 1,000 feet
Rationale: FAA Part 107 regulations limit drone operations to a
maximum altitude of 400 feet above ground level to avoid conflicts with
manned aircraft.
5. Which of the following is a requirement for obtaining a Remote
Pilot Certificate under Part 107?
a) Passing an FAA knowledge test
b) Holding a commercial pilot license
c) Completing 50 drone flights
d) Owning a drone
Rationale: The FAA requires remote pilots to pass a knowledge test
covering regulations, airspace, weather, and operational safety to
ensure they understand safe drone operation.
6. During a drone inspection, you notice a cracked propeller. What is
the best action?
a) Use it for short flights only
b) Replace it before flight
, c) Sand the crack smooth
d) Apply tape to cover the crack
Rationale: Cracked propellers can fail in flight. Replacing the damaged
part ensures flight safety and compliance with maintenance standards.
7. When conducting a pre-flight inspection, which of the following is
least critical?
a) Propeller condition
b) Battery level
c) Firmware updates
d) Drone’s color
Rationale: While drone color has no impact on flight safety, propellers,
battery, and firmware directly affect performance and safe operation.
8. What does the term “line-of-sight” mean in drone operations?
a) Seeing the drone through a camera feed
b) Being able to see the drone with your own eyes
c) Observing the drone on a GPS map
d) Tracking the drone via telemetry
Rationale: Visual line-of-sight is a regulatory requirement under Part
107, ensuring pilots can directly see and control the drone during flight.
9. Which weather condition is most hazardous for drone operations?
a) Clear skies
b) High winds
c) Mild cloud cover
d) Low humidity
Rationale: High winds can destabilize drones, making them difficult to
control and increasing the risk of accidents.
