What should a pilot do if the Aircraft Flight Manual (AFM) is missing?

When the Aircraft Flight Manual (AFM) is missing, the pilot's priority should be safety and compliance with regulations. The AFM contains critical information about the aircraft's operating limits, performance data, emergency procedures, and more. Operating without this manual can lead to significant risks, including the inability to make informed decisions about weight and balance, fuel management, and emergency situations.

Postponing the flight until the AFM is found ensures that the pilot has access to all necessary information to operate the aircraft safely. It is a necessary step to maintain the integrity and safety of the flight. Using an alternative manual is not advisable because alternative manuals may not contain the specific data required for the particular aircraft, and assumptions made in such a scenario could lead to unsafe conditions. Likewise, proceeding with caution or continuing the flight without the AFM would compromise safety and violate regulatory requirements. Therefore, postponing the flight is the most prudent and responsible action to take in this situation.
