Which action powers the transfer from the Center tank to the inner tanks?

• A. Transfer Valve and Jet Pump
• B. Pressure differential
• C. Manual pump
• D. Gravity feed

Answer: (A)

The transfer from the Center tank to the inner wing tanks is driven by the transfer valve in combination with a jet pump. When the transfer path is selected, the jet pump creates suction using motive fuel flow, pulling fuel from the Center tank into the inner wing tanks. The transfer valve directs this flow and ensures the fuel moves to the desired tanks, providing a controlled and reliable transfer. Gravity feed won’t drive this transfer in normal operation because the wing tanks are not positioned to provide a reliable vertical head, and the system relies on pumped flow for control. A manual pump could provide a backup, but it isn’t the normal powering method, and relying on pressure differential alone wouldn’t guarantee a controlled or adequate transfer.
