What is the idle N1 percentage range for ground operations?

The idle N1 percentage range for ground operations is generally set between 60% and 67%. This range is critical for ensuring that the engine operates efficiently during taxi and other ground activities without causing excessive wear or unnecessary fuel consumption. Operating within this range helps maintain optimal performance of the engine and provides the necessary thrust while on the ground, allowing for safe maneuverability of the aircraft. The importance of using this specific range lies in balancing engine performance with operational safety and efficiency during ground handling.
