What is the maximum Ng percentage during take-off?

During take-off in the Pilatus PC-12 NG, the maximum Ng percentage allowed is 104%. Ng represents the gas generator speed and is crucial for ensuring optimal engine performance and efficiency during critical phases of flight, such as take-off. Allowing up to 104% Ng during take-off helps provide the necessary power output to assist in achieving the required climb performance and acceleration.

The limits established for Ng are based on the engine’s design specifications and operational safety guidelines. Operating at or below this specified limit ensures the engine can reliably perform its functions while mitigating the risk of potential mechanical issues or engine damage. Adherence to this limit is particularly important during take-off, where engine performance is essential for safely initiating flight and avoiding obstacles.
