A method is provided for improving aircraft engine operating efficiency during flight in aircraft driven on the ground by electric taxi systems that extends engine warm up and cool down time during ground operations without increasing the time an aircraft spends on the ground. Aircraft are driven by electric taxi systems between landing and take off with the main engines simultaneously maintained at throttle setting for time periods that ensure even and symmetrical heating or cooling for all engine components. When the aircraft reaches a location where idle or take off thrust is required before take off, engine thrust may be increased without the adverse effects of differential thermal expansion of engine components during flight. Aircraft engines may be designed to rely on electric taxi operation and extended warm up and cool down times without delaying push back or taxi-in or otherwise negatively impacting airport operations.
