Which tank feeds the jet pump to Forward Main Tank?

• A. Aft Main Tank
• B. Forward Main Tank
• C. Supply Tanks
• D. Center Tank

Answer: (A)

The idea being tested is how fuel is cross-fed between tanks using a jet pump to fill a specific tank. In this arrangement, the jet pump pushes fuel into the Forward Main Tank, and the suction comes from the source tank. The standard source for that feed is the Aft Main Tank, because the system is designed so fuel can be drawn from the aft section and pumped forward to keep the Forward Main Tank topped, which helps manage balance and ensure a steady supply during different flight attitudes. While other tanks have roles in supplying fuel for other parts of the system, the Aft Main Tank is the intended source for the cross-feed to the Forward Main Tank.
