Show the answer and explanation

Correct answer: B. at all times.

  • A — incorrect No periodic interval appears in § 107.33; the requirement is continuous communication throughout the operation.
  • B — correct § 107.33(a) requires the remote pilot in command, the person manipulating the flight controls, and the visual observer to maintain effective communication with each other at all times.
  • C — incorrect The rule does not depend on the aircraft's distance from the crew; communication must be maintained during the entire operation.

BACKGROUND

Part 107 allows a remote pilot in command to use a visual observer (VO) to help keep the small unmanned aircraft in sight. When a VO is used, § 107.33 imposes conditions on the whole crew. The first is that the remote pilot in command, the person manipulating the flight controls, and the visual observer must maintain effective communication with each other at all times. This continuous link is what lets the VO's observations reach the person flying the aircraft in time to avoid a hazard.

STUDY TIP

Remember that the communication requirement in § 107.33(a) has no time interval or distance trigger; it applies at all times when a visual observer is used.

KEY POINTS

  • § 107.33 applies whenever a visual observer is used.
  • The crew must maintain effective communication with each other at all times.
  • There is no distance or interval condition on the communication requirement.
