What is the maximum fuel imbalance for takeoff in the CRJ 550/700/900?

The maximum fuel imbalance for takeoff in the CRJ 550/700/900 is 300 pounds. This limitation is set to ensure proper aircraft performance and handling characteristics during takeoff. An imbalance greater than this can negatively affect the aircraft's center of gravity, leading to potential control issues, particularly during critical phases of flight like takeoff and climb. Maintaining fuel levels within this specified limit helps ensure that pilots have adequate control authority over the aircraft and minimizes the risk of any adverse aerodynamic effects that could arise from uneven weight distribution.
