The amount of fuel used for computing empty weight and corresponding CG is....

Explanation:
When calculating the empty weight and the corresponding CG, you must include the fuel that cannot be used. This unusable fuel is physically present in the tanks and thus adds to the aircraft’s weight and shifts the CG, even though it can’t be pumped out or burned off. Usable fuel is fuel you will burn in flight, so it isn’t part of the empty weight calculation. Likewise, the total fuel on board includes both usable and unusable, but only the unusable portion belongs in the empty weight/CG calculation.
