Takeoff Weight Determination Procedures
Charts in the Aircraft Flight Manual (AFM) Performance Section

gross weight permitted by FAR 25 as well as associated
speeds and flight paths. The aircraft may be limited in
takeoff gross weight by the most restrictive of aircraft con-
ditions, airport conditions, and atmospheric conditions.
The flow chart below illustrates the steps to determine
