What is the maximum fuel quantity for pressure refueling?

• A. 19,594
• B. 14,580
• C. 14,810
• D. 19,000

Answer: (A)

When you’re refueling by applying pressure from the ground, you’re aiming to fill the tanks to their usable capacity—the amount the system is designed to hold and deliver safely. For this aircraft, that usable capacity under pressure refueling is 19,594 pounds. This value reflects the total fuel the tanks can store once you account for any unusable fuel that remains in the tanks and the limits of the fuel lines and vents, all within the pressure system’s safety constraints. The other numbers are smaller because they correspond to partial fills or configurations that don’t reach the full usable capacity when using pressure refueling.
