       <long_desc>This is the minimum throttle while on the ground For aircraft with internal combustion engines, this parameter should be set above the desired idle rpm. For electric motors, idle should typically be set to zero. Note that in automatic modes, "landed" conditions will engage idle throttle.</long_desc>
