How is fuel transferred from the Center tank to the inner tanks?

• A. By gravity feed
• B. By operation of a Transfer Valve and Jet Pump
• C. By manual pump using a hand crank
• D. By the aircraft's main hydraulic pump

Answer: (B)

Transferring fuel from the center tank to the inner wing tanks is done by a controlled path that uses a transfer valve combined with jet pumps. The transfer valve opens the connection between the center tank and the wing tanks, while the jet pumps provide the motive flow to move the fuel through that path. This setup lets fuel be moved as needed for engine feed and balance, regardless of aircraft attitude, since gravity alone cannot reliably supply flow in all flight attitudes. Manual pumping isn’t used on the A320, and the aircraft’s hydraulic pump isn’t involved in fueling.
