QUESTIONUnder § 107.15, who must check the small unmanned aircraft system prior to each flight to determine whether it is in a condition for safe operation?

  1. AA visual observer designated for the flight
  2. BAn FAA-certificated mechanic
  3. CThe remote pilot in command
Show the answer and explanation

Correct answer: C. The remote pilot in command

  • A — incorrect A visual observer helps with see-and-avoid; § 107.15(a) assigns the preflight condition check to the remote pilot in command.
  • B — incorrect Part 107 does not require a certificated mechanic to perform the before-flight check; § 107.15(a) names the remote pilot in command.
  • C — correct § 107.15(a) places the duty on the remote pilot in command to check the system prior to each flight.

BACKGROUND

Section 107.15 is titled "Condition for safe operation." Paragraph (a) states that no person may operate a civil small unmanned aircraft system (sUAS) unless it is in a condition for safe operation, and that prior to each flight the remote pilot in command must check the sUAS to determine whether it is in that condition. The rule applies to the whole system, which includes the aircraft, the control station and the links between them. The check is required before every flight, not once per day or once per battery.

STUDY TIP

Remember that § 107.15 assigns two duties to the remote pilot in command: check before each flight, and stop if the system becomes unsafe.

KEY POINTS

  • § 107.15(a) requires the sUAS to be in a condition for safe operation.
  • The remote pilot in command must check the sUAS prior to each flight.
  • The duty is per flight and belongs to the remote pilot in command, not a mechanic or observer.
