Before departure the remote pilot must ensure that all persons directly participating in the operation understand which of the following?

Part 107 requires the remote pilot in command to ensure that all persons directly participating in the operation are informed about the operating conditions, emergency procedures, contingency procedures, roles and responsibilities, and potential hazards. The requirement recognises that a crew is only as safe as its least informed member: an observer who does not know the abort call, a spotter unaware of the power lines, or a client's employee standing where the aircraft will land can undo careful planning by the pilot. The briefing is also what establishes who is a participant, which matters directly for the rules on operating over people, since participants are treated differently from uninvolved persons. It is a short conversation, but it is a regulatory obligation with the responsibility resting on the remote pilot in command specifically — not shared, and not delegable to whoever organised the job.

Part 107 requires the remote pilot in command to ensure all directly participating persons understand the operating conditions, emergency and contingency procedures, their roles and responsibilities, and the hazards involved.

Part 107 places on the remote pilot in command the duty to ensure all directly participating persons are informed of operating conditions, emergency and contingency procedures, roles and responsibilities, and potential hazards before flight.

Everyone Involved Gets Briefed — conditions, emergencies, roles, hazards. Four items, one conversation, before launch.

The briefing also establishes who counts as a directly participating person, which matters for the rules on operating over people.

• •Briefing the observer but not the client's on-site staff
• •Treating the briefing as optional courtesy rather than a requirement
• •Assuming the duty is shared rather than resting on the remote pilot in command
