1. What is the primary purpose of a pre-flight inspection on a
commercial drone?
A. To increase flight speed
B. To ensure regulatory compliance only
C. To ensure the drone is safe and fully operational before flight
D. To calibrate GPS during flight
Rationale: Pre-flight inspections help identify mechanical, electrical, and
software issues that could cause accidents or mission failure.
2. Which component is essential for maintaining drone stability in
flight?
A. Camera gimbal
B. Inertial Measurement Unit (IMU)
C. LED lights
D. Propeller guards
Rationale: The IMU measures acceleration and angular velocity to help
stabilize the drone.
3. What does VLOS stand for in drone operations?
,A. Vertical Line of Sight
B. Vehicle Launch Operating System
C. Visual Line of Sight
D. Variable Lift Operational Signal
Rationale: VLOS means the operator must maintain direct visual contact
with the drone.
4. What is the main risk of flying a drone in high winds?
A. Increased battery life
B. Improved camera stability
C. Loss of control and drift
D. Faster GPS lock
Rationale: Strong winds can push the drone off course and overwhelm
its motors.
5. Which frequency band is commonly used for consumer drone
communication?
A. 1.2 GHz only
B. 900 MHz only
C. 2.4 GHz and 5.8 GHz
D. 10 GHz
Rationale: These bands balance range and data transmission speed for
control and video.
6. What is geofencing in drone technology?
, A. A manual flight control mode
B. A battery-saving feature
C. A virtual boundary restricting drone flight areas
D. A camera stabilization tool
Rationale: Geofencing prevents drones from entering restricted or
dangerous zones.
7. What should you do if GPS signal is lost during flight?
A. Increase altitude immediately
B. Turn off motors
C. Switch to manual or return-to-home mode if safe
D. Ignore it and continue flight
Rationale: Loss of GPS affects positioning; safe recovery procedures are
essential.
8. Which weather condition is most dangerous for drone operations?
A. Light cloud cover
B. Mild humidity
C. Thunderstorms
D. Overcast skies
Rationale: Thunderstorms introduce lightning, wind shear, and heavy
precipitation.
9. What does Return-to-Home (RTH) function do?
