QUESTIONUnder § 107.15, what must a remote pilot in command do if, during flight, he or she has reason to know that the small unmanned aircraft system is no longer in a condition for safe operation?

  1. AContinue the flight and report the condition to the FAA afterward
  2. BContinue the flight if a visual observer is watching the aircraft
  3. CDiscontinue the flight of the small unmanned aircraft
Show the answer and explanation

Correct answer: C. Discontinue the flight of the small unmanned aircraft

  • A — incorrect § 107.15(b) prohibits continuing the flight; no after-the-fact report substitutes for stopping the flight.
  • B — incorrect The use of a visual observer does not change the requirement; § 107.15(b) bars continued flight regardless of crew composition.
  • C — correct § 107.15(b) states that no person may continue flight of the small unmanned aircraft when he or she knows or has reason to know that the system is no longer in a condition for safe operation.

BACKGROUND

Section 107.15 of 14 Code of Federal Regulations (CFR) part 107 sets the condition-for-safe-operation rule. Paragraph (a) prohibits operating a civil small unmanned aircraft system (sUAS) unless it is in a condition for safe operation and requires the remote pilot in command to check the system before each flight. Paragraph (b) extends that duty into the flight itself: once the remote pilot in command knows or has reason to know that the system is no longer safe, the flight may not be continued. The standard is knowledge or reason to know, so a pilot cannot ignore obvious warning signs.

STUDY TIP

Remember that § 107.15 has two halves: a preflight check and an in-flight duty to stop. Questions often test the in-flight half.

KEY POINTS

  • § 107.15(a): check the sUAS before each flight for safe operating condition.
  • § 107.15(b): do not continue flight once you know or have reason to know the sUAS is no longer safe.
  • No report, waiver, or visual observer replaces the duty to discontinue the flight.
