Question 8
Domain 1: FAA Part 107 OperationsWhat should be included in a thorough preflight inspection of a multirotor sUAS?
Correct answer: B
Explanation
A thorough preflight inspection checks the aircraft’s condition and readiness before flight, including the "airframe, propellers, motors, battery" and any "control surfaces or settings." It also requires verifying the command-and-control link so the multirotor can be safely operated and respond properly to pilot inputs.
Why each option is right or wrong
A. Only the battery level check
B. Airframe, propellers, motors, battery, control surfaces or settings, and control link verification
14 CFR § 107.49 requires a preflight inspection before each flight to determine whether the small unmanned aircraft is in a condition for safe operation. For a multirotor, that inspection necessarily covers the structural condition of the airframe, propeller integrity, motor function, battery status, and any flight-control settings that affect stability and responsiveness, because defects in any of these items can cause loss of control. The command-and-control link must also be verified under the operating requirements in 14 CFR Part 107 so the aircraft will reliably receive pilot inputs throughout the flight.
C. Only the camera operation
D. Only the GPS signal strength
