What is the maximum Ng during normal operations?

The maximum Ng during normal operations is 104%. This value represents the peak of the gas generator speed during typical flight conditions when the engine is performing optimally under normal operational limits. Exceeding this percentage can lead to potential engine damage or reduced reliability.

Understanding the operational limits, including Ng, is critical for pilots to ensure safe and efficient flight operations. The specifications are set based on extensive testing and operational experience, providing a margin of safety for engine performance. Operating within these parameters helps maintain engine health and prolong overall aircraft reliability.
