At what fuel imbalance level does the auto balance system typically engage?

The auto balance system in the T-6B is designed to maintain an even distribution of fuel between the left and right fuel tanks, which is critical for maintaining aircraft stability and performance. Typically, this system engages when there is a fuel imbalance of 20 pounds.

This specific threshold helps ensure that the aircraft's center of gravity remains balanced during flight, enhancing safety and handling. When the imbalance reaches this level, the auto balance system activates to transfer fuel from the fuller tank to the emptier tank automatically, thus working to rectify the imbalance without pilot intervention.

Understanding the engagement level of 20 pounds is important for pilots, as it ensures that they can rely on this system to assist in maintaining optimal fuel distribution, which is vital during various phases of flight.
