During an automated small UA operation, the aircraft is flying a pre-programmed mission from the onboard autopilot. If the remote pilot in command loses the control link to the aircraft, AC 107-2A explains that the aircraft will most likely —
Why: AC 107-2A § 5.2.3 explains that during automated flight, control inputs come from components onboard the aircraft rather than the control station; if the control link is lost, the aircraft continues flying its programmed mission or returns home to land rather than stopping.
Invents an automatic motor shutoff; AC 107-2A describes the aircraft continuing its mission or returning home, not cutting power on link loss.
Assumes a fixed orbit-and-wait behavior that AC 107-2A does not describe as the general case for automated flight losing its control link.
