What is the maximum fuel imbalance permissible for takeoff?

The maximum fuel imbalance permissible for takeoff is 300 pounds. This limit is set to ensure the aircraft maintains acceptable center of gravity and performance characteristics during the critical phases of flight, particularly during takeoff. Imbalances beyond this threshold could affect the aircraft's handling, stability, and control, especially in the event of an engine failure during takeoff or climb out.

By maintaining the fuel imbalance at or below this limit, pilots can ensure optimal aircraft performance, which is crucial for safe and efficient operations. This regulation is part of the overall safety protocols that guide operations for the CRJ550 and similar aircraft, helping to minimize risks during flight.
