How does the AH-64E's fuel system maintain supply under maneuvering loads?

• A. It uses gravity feed from fuel tanks to engines.
• B. It uses fuel management with tank cross-feed capability and automatic balancing to ensure continuous supply to both engines.
• C. It relies on external fuel supply during flight.
• D. It uses fuel only from the left tank.

Answer: (B)

The fuel system keeps both engines fed during maneuvers by using tank cross-feed and automatic balancing. That means fuel can be moved between tanks and routed to either engine as needed, with valves and controls automatically directing flow to prevent any engine from starving. Engine-driven pumps pressurize the feed, and the system monitors levels and pressures to balance fuel distribution, so even during high-G turns or unusual attitudes, both engines receive a continuous supply. Gravity feed isn’t reliable in dynamic flight, since sustained maneuvers can shift fuel away from the feeds. External in-flight fuel supply isn’t how the aircraft is designed to operate, and relying on a single tank would risk losing power on one engine during maneuvers.
