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).

This AD requires modification of the electrical power supply of the landing gear anti-skid unit for certain aircraft and also requires a revision to the Airplane Flight Manual (AFM) to provide the flight crew with procedures for calculating the accelerate-stop distance for certain conditions, and installation of a new ground idle stop assembly, as well as new placards on the top cover of the pedestal, which terminates the requirements for the AFM revision.
I told the crew, "I have betas," and continued to move the power levers toward ground idle.
Moving the power levers from ground idle to flight idle, and then moving them up to max power in an attempt to fly again, would lead me outside of the performance-numbers range I had planned for takeoff and land data.
I heard the skipper advise my XO, "Just get the engines shut down; there's no need to worry about lowspeed ground idle.
I brought back the power levers to ground idle and held back pressure on the nose until our mainmounts crossed over the arresting gear.
As he brought the power levers out of flight idle into ground idle and then maximum reverse, I noticed the plane started veering to the left side of the runway.
I told him to come out of reverse and to go back into ground idle.
The crew completed the shutdown checklist and put the engines into low-speed ground idle (E-2C+ engines must run for two minutes at that speed to prevent problems with the fuel nozzles and consequent turbine damage).
