Which component moves fuel from the center tank to the main tanks?

• A. Transfer ejectors
• B. Scavenge ejectors
• C. Main ejectors
• D. Boost pumps

Answer: (A)

Transfer ejectors handle moving fuel from the center tank into the main wing tanks. They use a flow of motive fuel to create suction, drawing fuel from the center tank so it can be fed into the main tanks and onward to the engines as needed. This keeps the engines supplied and helps maintain proper balance as fuel is consumed from the center tank. The other components have different jobs: scavenge ejectors remove remaining fuel from tank sumps and feed it back into the system, boost pumps provide the pressure to push fuel to the engine pumps, and main ejectors aren’t the mechanism used for transferring fuel between the center and main tanks.
