What must each main tank exceed for takeoff with a fuel load in the center tank?

The correct answer is rooted in the operational requirements for the CRJ 200 regarding fuel management. For takeoff with fuel loaded in the center tank, it is mandated that each main tank must contain a minimum fuel quantity to ensure safe operations. This minimum is established to maintain the aircraft's center of gravity, ensure proper fuel distribution during flight, and prevent potential issues that might arise from inadequate fuel in the main tanks.

Specifically, the requirement is set at exceeding 4,400 lbs in each main tank when fuel is present in the center tank. This ensures that there is a sufficient reserve and flow capability for the engines, contributing to both safety and performance during takeoff.

Other fuel quantities mentioned do not meet the necessary safety margins. For instance, having only 3,000 lbs, 4,000 lbs, or even 5,000 lbs does not align with the operational limitations of the aircraft regarding fuel management and center of gravity stability when utilizing the center tank. Thus, the correct threshold must be adhered to, reinforcing the importance of maintaining the 4,400 lbs minimum in each main tank during takeoff with center tank fuel.
