A certificated remote pilot sets up a flight, accepts responsibility for the operation, but has a crew member physically operate the controller while the pilot monitors. Under Part 107, what is required of the crew member?
Why →Under 14 CFR § 107.12, a person who does not hold a Remote Pilot Certificate may manipulate the controls of a small UAS if a certificated remote pilot with a small UAS rating is present and able to immediately take control. The certificated pilot remains the remote PIC and retains all responsibilities under § 107.19, including responsibility for safe operation of the aircraft.
The trap →PIC status under Part 107 is a legal designation tied to responsibility, not to who physically holds the controller. The certificated pilot is the PIC whether or not they are the one flying.
Field note →The certificated PIC must remain in a position to immediately take over if needed. Handing the controller to someone and leaving the area would transfer de facto control without authority, which violates § 107.12.
