What is the setting for N2 at idle?

The setting for N2 at idle is within the range of 56.5% to 68.0%. This is the targeted operational range indicating the rotational speed of the N2 stage of the engine, which is crucial for ensuring proper maintenance and performance of the aircraft’s engines during idle conditions. Operating within this range helps to maintain engine efficiency and reliability, reducing wear and preventing potential mechanical failures.

Idle performance is important for safe operations as it prevents the engines from stalling and ensures that adequate thrust is available for taxiing and other ground maneuvers. Understanding these limitations is essential for pilots and crew as it directly impacts flight safety and engine performance.
