At what fuel weight difference does the Auto-Balance System activate in the Pilatus PC-12 NG?

The Auto-Balance System in the Pilatus PC-12 NG is designed to maintain even fuel balance between the left and right fuel tanks. This system activates when there is a fuel weight difference of 68 pounds or more between the two tanks. Once this threshold is reached, the Auto-Balance System will transfer fuel from the tank with the higher fuel weight to the tank with the lower weight to help maintain balance and improve aircraft handling and performance.

In aviation, maintaining balance is crucial for stability and efficiency during flight, especially during critical phases such as takeoff and landing. The 68-pound activation threshold is carefully designed to ensure that the system operates efficiently without frequent activation, which might lead to unnecessary fuel movement and added complexity.
