What is zero fuel weight?

What is zero fuel weight?

• A. The airplane's weight without usable fuel.
• B. The weight after fuel burnoff but before landing.
• C. The weight including all fuel on board.
• D. The weight at takeoff including payload.

Answer: (A)

Zero fuel weight is the airplane’s weight with everything on board except usable fuel. It includes the empty aircraft, crew, passengers, baggage, cargo, and all non-fuel items, but not the usable fuel that will be burned during flight. This distinction matters because fuel adds weight, and weight-and-balance planning uses zero fuel weight to separate the payload-related load from the fuel load. In practice, takeoff weight equals zero fuel weight plus the usable fuel on board. The other scenarios describe weights that either include fuel or reflect weight after fuel has been burned, so they aren’t zero fuel weight.
