To whom are flight crew members responsible for the safe operation of the aircraft?

Flight crew members are responsible for the safe operation of the aircraft primarily to the Aircraft Commander. The Aircraft Commander holds ultimate authority over the aircraft and the crew, which includes making decisions that affect the safety, operation, and mission of the flight. This responsibility includes ensuring that all crew members are properly briefed, that safety protocols are followed, and that any operational decisions made during the flight align with both safety and mission objectives.

In comparison, while individuals like the Senior Airman, Operations Officer, and Chief Master Sergeant play important roles within the aviation unit, they do not have the authority or responsibility for the overall safety of flight operations like the Aircraft Commander does. Their roles may involve operational management, administrative support, or addressing personnel issues, but when it comes to the aircraft’s operation, it is the Aircraft Commander who ultimately ensures safety and compliance with regulations and protocols.
