Are Aircraft Flight Manuals (AFM) required to be in the aircraft at all times?

Aircraft Flight Manuals (AFMs) are indeed required to be present in the aircraft at all times. The AFM serves as a critical source of information for pilots, containing essential data related to the airplane's operating procedures, performance characteristics, and limitations. This information is vital for ensuring safe operations during flight.

Having the AFM on board helps pilots quickly reference the necessary procedures and performance data in the event of an abnormal situation or during routine flight operations. Regulations set forth by aviation authorities specify that the AFM must be available to the flight crew whenever the aircraft is in operation, emphasizing the importance of immediate access to this important documentation. This requirement is in place not just for routine flights but also to address any unforeseen events, making it essential for ensuring pilot preparedness and safety in all phases of flight.
