What is the Maximum Zero Fuel (ZFW) Weight for the C-5 Galaxy?

Explanation:
Maximum Zero Fuel Weight is the weight limit you can load onto the aircraft with payload and crew, but without any usable fuel on board. It matters because it defines how heavy the airframe and its center of gravity can be before fuel is added; the structure and balance must be able to handle that payload even without fuel. For the C-5 Galaxy, the published maximum ZFW is 686,190 pounds. This means payload plus crew must not exceed that weight before you start fueling. The relationship to takeoff weight helps you plan how much fuel you can carry: with a maximum takeoff weight of 840,000 pounds, the available fuel alongside the maximum payload is 840,000 minus 686,190 = 153,810 pounds of usable fuel. The other numbers listed correspond to different weight limits (like MTOW or other empty/operating weights) and are not the ZFW.
