What is the required fuel level in each wing tank to permit a fuel load in excess of 500 lbs in the center tank during takeoff?

To allow for a fuel load in excess of 500 lbs in the center tank during takeoff, the correct requirement is to have a minimum of 4,400 lbs of fuel in each wing tank. This limitation is based on ensuring proper aircraft balance and preventing adverse handling characteristics that can arise from an imbalanced fuel configuration, especially during critical phases of flight like takeoff.

Maintaining this fuel level helps to ensure that the aircraft's center of gravity remains within safe operational limits when fuel is drawn from the center tank. If the fuel in the wing tanks were lower than this specified amount, the risk of exceeding the weight and balance limitations during flight increases, which could compromise safety and performance.

The other quantities do not meet the specifications detailed in the aircraft’s operational limits and could lead to difficulties in achieving a safe takeoff or maintaining adequate performance during flight.
