What is the primary purpose of establishing a safety briefing with a visual observer before operations begin?
Why →A pre-operation briefing with the visual observer ensures coordinated operations: the VO understands how to communicate aircraft position and hazards to the remote PIC, knows the agreed signals for emergency actions, and understands their specific role (scanning assigned sectors, alerting to traffic, etc.). There is no FAA paperwork requirement for this briefing.
The trap →No FAA regulation requires written acknowledgments for safety briefings in Part 107 operations. The VO cannot assume liability from the remote PIC. The PIC retains full legal responsibility. The briefing is a safety tool, not a legal formality.
Field note →Key VO briefing topics: what sectors to scan, how to communicate (hand signals if loud environment, radio protocol), what the abort signal is, where to stand, and what to do if you lose sight of the aircraft.
