ground idle

ground idle

The governed RPM on the ground with throttles set to the minimum or fully back position. Normal ground idling is in the range of 60 to 70% of the maximum RPM. In the case of twin-spool engines, it is the N1 RPM (RPM of the low-pressure compressor) that is the benchmark and not N2 (RPM of the high-pressure compressor).
