QUESTIONUnder § 107.33, when a visual observer is used, what must the remote pilot in command, the person manipulating the flight controls, and the visual observer maintain with each other at all times?

  1. AA two-way radio link on a discrete frequency
  2. BEffective communication
  3. CPhysical proximity within 100 feet
Show the answer and explanation

Correct answer: B. Effective communication

  • A — incorrect § 107.33 does not prescribe any particular communication equipment or frequency; it requires only that communication be effective.
  • 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 Part 107 sets no distance limit between crew members; the requirement in § 107.33(a) is effective communication.

BACKGROUND

Section 107.33 of 14 CFR part 107 lists the requirements that apply whenever a visual observer is used. Paragraph (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. Paragraph (b) requires the remote pilot in command to ensure the visual observer can see the unmanned aircraft in the manner specified in § 107.31. Paragraph (c) requires the three to coordinate in scanning the airspace for collision hazards and maintaining awareness of the aircraft's position through direct visual observation. The regulation does not specify how the communication must be carried out.

STUDY TIP

For visual observer questions, focus on the three duties in § 107.33: effective communication, the observer's ability to see the aircraft, and coordinated scanning.

KEY POINTS

  • § 107.33(a): effective communication among remote PIC, controls operator, and visual observer at all times.
  • § 107.33(b): the remote PIC must ensure the observer can see the aircraft per § 107.31.
  • § 107.33(c): the crew coordinates to scan for collision hazards and track the aircraft visually.
