What is the maximum fuel imbalance permitted during landing?

The maximum fuel imbalance permitted during landing is 300 lbs. This limit is crucial because an excessive fuel imbalance can adversely affect the aircraft's handling characteristics, stability, and landing performance. Maintaining a balance in fuel distribution is essential for ensuring that the aircraft can operate safely and effectively, particularly during critical phases of flight like landing.

In the context of an aircraft's performance, a fuel imbalance can lead to asymmetrical thrust and alter the aerodynamic forces acting on the aircraft, making it more challenging to control during landing. Hence, regulatory and manufacturer guidelines specify this fuel imbalance limit to enhance safety. Such guidelines are established based on extensive testing and operational experience to ensure the best performance and safety standards during landing.

Other options present higher limits that exceed the safety margin established for landing, which could lead to performance issues and potential risks during this critical phase of flight.
