What should the CC do after administering first aid to an incapacitated pilot with no other pilot available?

The correct response involves the critical role of the cabin crew member (CC) in ensuring the safety of both the passengers and the aircraft in an emergency situation. After administering first aid to an incapacitated pilot, and with no other pilot available, the CC’s immediate action should be to assist the operating pilot. This is essential because, in the absence of a second pilot, the operating pilot may require additional support, whether in managing the aircraft or communicating with air traffic control. The cabin crew's assistance can help stabilize the situation, which is vital for maintaining safety during flight.

Engaging actively in supporting the operating pilot can also involve handling communications, managing passenger needs, and preparing for any necessary emergency landing procedures. The cabin crew is trained to step in during emergencies, and assisting the pilot directly aligns with their responsibilities to ensure the continued safe operation of the aircraft.
