Show the answer and explanation

Correct answer: A. That the aircraft poses no undue hazard to other people, aircraft, or property

  • A — correct § 107.19(c) requires the remote pilot in command to ensure the small unmanned aircraft will pose no undue hazard to other people, other aircraft, or other property if control is lost for any reason.
  • B — incorrect Part 107 does not mandate an automatic return-to-launch function or any time limit; it requires that no undue hazard result from a loss of control.
  • C — incorrect Registration is a separate requirement under § 107.13 and does not address what happens during a loss of control.

BACKGROUND

Section 107.19 describes the remote pilot in command (RPIC). The RPIC is directly responsible for and is the final authority as to the operation of the small unmanned aircraft system (UAS). Paragraph (c) specifically addresses loss of control: the RPIC must ensure the small unmanned aircraft will pose no undue hazard to other people, other aircraft, or other property in the event of a loss of control for any reason. This covers events such as a lost control link or a fly-away. Planning where the aircraft could go, and what it could hit, if control is lost is therefore part of the RPIC's basic duty before and during every flight.

STUDY TIP

Remember that § 107.19(c) is written for the worst case: plan every flight so that a loss of control for any reason will not endanger others.

KEY POINTS

  • The RPIC must ensure no undue hazard results from a loss of control for any reason.
  • The duty covers other people, other aircraft, and other property.
  • The RPIC is the final authority for the operation under § 107.19(b).
