Abstract
The present disclosure is directed to a method for determining an aircraft minimum low pitch setting for a propeller assembly and minimum gas generator idle speed for a gas generator, in which the propeller assembly and the gas generator together comprise a gas turbine engine. The method comprises determining, via one or more controllers, an operating condition of the aircraft based at least on a weight on wheels (WoW) signal and a throttle lever position. The WoW signal produces a first mode or a second mode different from the first mode, and the throttle lever position defines at least a takeoff position and an idle power position.
