When flight crew are confronted with an emergency or abnormal situation whilst in flight, they normally prioritise their immediate actions in the following order:
Aviate;
Navigate;
Communicate.
Aviate
The pilot’s immediate priority is to ensure the safe flight path and condition of the aircraft. This not only includes the flying of the aircraft but also the completion of checklist drills. The safe flight path may even include the initiation of a controlled rapid descent.
