Center tank capacity is

• A. 30,500 lbs
• B. 25,000 lbs
• C. 20,000 lbs
• D. 35,000 lbs

Answer: (A)

Center tank capacity is the maximum usable fuel weight stored in the aircraft’s center reservoir, which is designed to provide the bulk of long-range fuel while keeping balance in check. The value of 30,500 pounds reflects the amount of fuel the center tank can hold before hitting weight or structural limits, making it the largest single-tank capacity among the tanks and a key contributor to endurance. That amount corresponds to roughly 4,550 gallons of Jet fuel (about 6.7 lb per gallon), illustrating why the center tank is designed to be so large. The smaller figures would not provide the same range benefit and, in many configurations, would not fit within the aircraft’s structural or CG limits, so 30,500 pounds is the appropriate capacity for this tank.
