Notes:

Unusable fuel increases to 53.9 US Gal. (365 lbs.) in each tank if any of the associated electric fuel pumps is inoperative.

When performing pressure refueling, the usable fuel quantity in each tank may be reduced by 13.2 US Gal (89.32 lbs).

The values above have been determined for an adopted fuel density of 6.767 lb/US Gal.
