Which device moves fuel from the Center tank to the inner tanks?

• A. By gravity from the center tank
• B. By operation of a Transfer Valve and Jet Pump
• C. By an electric pump integrated into the inner tanks
• D. By manual transfer lever in the cockpit

Answer: (B)

Fuel movement from the center tank to the inner wing tanks is achieved by a transfer valve in the center tank together with jet pumps located in the wing tanks. When the fuel management system decides crossfeed is needed, the transfer valve opens and directs center-tank fuel into the wing-tank path. The jet pumps then physically move that fuel into the inner wing tanks, providing the flow and balance required for proper fuel distribution. Gravity isn’t relied on for this transfer because attitudes and flight conditions vary, and the system is designed to control the transfer reliably. There isn’t a cockpit manual lever to perform this transfer, and an electric pump inside the inner tanks isn’t the mechanism used for moving fuel from the center to the inner tanks.
