What action best helps manage a fuel imbalance in flight?

• A. Adjust crossfeed carefully and monitor balances, following MEL/CDL guidance
• B. Ignore small imbalances
• C. Jettison fuel
• D. Close crossfeed completely

Answer: (A)

Balancing fuel in flight is about using the crossfeed system to move fuel between wings so the aircraft remains symmetric and controllable. The best action is to adjust crossfeed carefully and monitor the balance, following MEL/CDL guidance. Crossfeed lets fuel transfer from one wing to the other through a valve, enabling you to correct any imbalance without dumping fuel or altering the total fuel on board. The MEL (Minimum Equipment List) and CDL (Configuration Deviation List) provide specific imbalance limits and the required steps to take, so you stay within safe limits and avoid overcorrecting or compromising fuel distribution to the engines. This approach is best because it is immediate, controllable, and done using approved procedures. It keeps more fuel on board, preserves safe handling, and minimizes risk compared to harsher measures. Ignoring a small imbalance may seem simple, but imbalances can worsen as fuel burns unevenly. Jettisoning fuel is not a routine balancing method and often isn’t permitted or desirable due to safety, weight, and environmental concerns. Closing the crossfeed would prevent balancing actions, leaving the imbalance unresolved.
