Which statement best describes zero fuel weight?

Which statement best describes zero fuel weight?

• A. Weight including fuel at max capacity
• B. Weight of payload only
• C. Weight of aircraft with full tanks
• D. Maximum weight without fuel, with any extra weight carried as fuel only

Answer: (D)

Zero fuel weight describes the aircraft’s weight with no usable fuel in the tanks. It includes the airframe, systems, crew, and all payload, but excludes fuel. The statement that best fits is the one that says the maximum weight without fuel, with any extra load carried as fuel only. This captures the idea that you first establish the zero fuel limit, and any additional weight beyond that is added as fuel to reach the takeoff weight. The other options mix in fuel or limit the weight to payload or full tanks, which are not what zero fuel weight represents.
