A method is provided that extends available aircraft engine warm up and cool down times without extending total aircraft time on the ground. Aircraft that have engines with longer than average or longer than typical warm up and cool down times and are equipped with electric taxi systems are driven during hybrid taxi-out and taxi-in periods when the aircraft engines at lowest throttle settings are operating simultaneously with the electric taxi drive systems to move the aircraft during ground travel. The hybrid taxi-out and taxi-in periods ensure optimal steady, even warm up and cool down of engine components by takeoff and upon arrival and avoid thermally-induced structural deformations of engine components that adversely affect engines during flight. Aircraft engines may be designed to rely on the extended warm up and cool down times provided by the hybrid taxi periods without increasing aircraft ground travel time or negatively impacting airport operations.
