Which statement best defines the maximum weight in weight-and-balance terms?

• A. The maximum takeoff weight
• B. The maximum landing weight
• C. Authorized weight of the aircraft and its contents
• D. The structural weight limit

Answer: (C)

In weight-and-balance calculations, the maximum weight is the total weight the aircraft is certified to carry, including the aircraft itself and everything on board. This authorized weight of the aircraft and its contents sets the cap for weight and balance calculations and ensures the airplane stays within structural and stability limits during all phases of flight. It includes empty weight, crew, passengers, baggage, fuel, and any other payload.

This is why the choice describing the authorized weight of the aircraft and its contents is best. The other options refer to specific limits for particular phases or aspects—maximum takeoff weight is about takeoff, maximum landing weight is about landing, and the structural weight limit is a design constraint. Those are important, but the general, all-encompassing limit used in weight-and-balance terms is the authorized weight of the aircraft and its contents.
