Can fuel transfer be accomplished on the ground?

• A. Yes
• B. No
• C. Only with engines off
• D. Only with the APU running

Answer: (A)

Fuel transfer on the ground is possible because the aircraft’s fuel system includes pumps that can move fuel between tanks while the airplane is parked. This capability lets you balance weight and center of gravity before start and taxi, which helps ensure a safe and efficient takeoff. The transfer pumps are powered by the APU or ground power, so engines don’t have to be running just to adjust the distribution. This makes it practical to even out left and right wing tank levels or shift fuel into the center tank as part of preflight planning. In short, you can perform fuel transfer on the ground to achieve the desired balance and readiness for flight.
