ground idle ground idleThe 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). |
