What is the fuel imbalance limit allowed between sides?

The fuel imbalance limit for the King Air 350 is set at 300 lbs. This limit is critical to maintain the aircraft’s performance and ensure stability during flight. When one tank has significantly more fuel than the other, it can cause an asymmetrical weight distribution. Such imbalances can lead to handling issues, increased drag, or even adverse aerodynamic effects that might compromise safety and control of the aircraft.

Keeping a fuel imbalance within this limit helps ensure that the aircraft operates efficiently and within safe parameters. Exceeding this limit could lead to complications during flight, including difficulty in controlling the aircraft and increased risk of structural stress. This limit is established following operational guidelines designed to promote safe flying practices and optimize performance during all phases of flight.
