Before a commercial flight, a remote pilot briefs the client and two bystanders who will be in the operations area. The briefing covers emergency abort signals, where to stand, and what to do if the aircraft malfunctions. Which regulation most directly supports this briefing requirement?

Why →Under § 107.19(a), the remote PIC is responsible for the safety of the small unmanned aircraft operation. This responsibility extends to everyone in the operations area, including clients and bystanders. Briefing participants on emergency procedures, safe standing positions, and abort signals is how the remote PIC discharges that duty before the flight begins. It is not explicitly required by a single regulation but flows directly from the PIC's overall safety responsibility.

The trap →§ 107.9 covers post-incident reporting, not pre-flight safety management. § 107.39 applies specifically to sustained flight over non-participating persons, which involves different regulatory criteria. The PIC's general safety duty in § 107.19 is the broader foundation for pre-flight briefings.

Field note →A brief pre-flight safety talk takes under two minutes and creates a documented basis for your professionalism if a claim ever arises. Cover four things: where to stand, what the abort signal is, what to do if the aircraft comes toward you, and not to approach the aircraft until the rotors have stopped.
