What is the maximum zero fuel weight?

The maximum zero fuel weight refers specifically to the maximum weight of an aircraft when it is loaded with cargo and passengers, but without any fuel on board. Option B, which states that it is the weight limit without considering fuel, accurately describes this definition.

This weight is important in aviation as it helps ensure the structural integrity of the aircraft during flight. Exceeding the zero fuel weight can increase the risk of structural failure because the aircraft is designed to bear loads up to a certain limit without the additional stress that fuel weight would add.

The other options do not correctly define the maximum zero fuel weight. The total weight with full fuel pertains to a different measurement and relates to the maximum takeoff weight. The weight of the empty aircraft does not take into account any load, and the maximum takeoff weight includes the weight of the fuel, cargo, and passengers. Thus, the correct understanding of maximum zero fuel weight is crucial for safe operational limits of an aircraft.
