The Beechjet 400A fuel storage system consists of which tanks?

• A. Four independent wing tanks
• B. A single central fuel tank
• C. Two independent wing tanks, two forward fuselage tanks, two mid fuselage tanks, and an aft filler tank
• D. Two wing tanks and two forward fuselage tanks

Answer: (C)

The Beechjet 400A uses a distributed fuel storage system to keep the airplane balanced and fuel management flexible as weight shifts during flight. Fuel is not stored in a single central tank but in multiple tanks placed in both wings and along the fuselage so distribution can be controlled to maintain the desired center of gravity.

Two independent wing tanks provide the primary fuel storage and allow crossfeed between wings to keep the aircraft balanced. Two forward fuselage tanks position fuel toward the nose, helping manage balance during loading and early phases of flight. Two mid fuselage tanks add to the overall capacity and support CG control as fuel is burned from different sections of the aircraft. The aft filler tank serves as a reserve/trim tank toward the rear, aiding aft CG management and ensuring fuel can be added or redistributed as needed during operation.

This combination—two wing tanks, two forward fuselage tanks, two mid fuselage tanks, and an aft filler tank—best matches the Beechjet 400A’s fuel storage arrangement. Other options either understate the number of tanks or describe a single central tank, which would not provide the same distribution and CG management capabilities.
