A remote pilot is conducting a solo mapping flight when they experience sudden dizziness and cannot safely maintain situational awareness of the aircraft. No visual observer is present. What is the correct action?

Why →Under § 107.19, the remote PIC must not operate if their physical or mental condition prevents safe operation. Dizziness is an immediate fitness disqualifier. Return-to-home is the fastest way to get the aircraft on the ground without requiring precise control inputs from an impaired operator. The pilot should activate RTH, move to a safe seated position, and monitor the descent. Mission data is not a safety consideration.

The trap →Continuing the flight at reduced speed puts mission completion ahead of safety, violating § 107.19. Handing the controller to a bystander hands a small unmanned aircraft to an uncertified person with no knowledge of the aircraft or airspace. Under § 107.12, only a certificated remote pilot or a person under direct supervision of a certificated pilot may manipulate the controls.

Field note →The IMSAFE checklist exists precisely for this scenario. The I stands for Illness. Any physical symptom that degrades awareness or reaction time is a no-fly condition before launch, and a land-now condition if it develops in flight.
