Abstract:
1. A method of operating a multi-engine aircraft comprising: (a.) providing a first jet engine having a thrust adequate to takeoff, climb, cruise, and land the aircraft at full gross weight, and providing a second jet engine having a thrust greater than the thrust of the first jet engine as a result of limiting the first jet engine's maximum thrust capability, but otherwise being equally powered, each of the first and second jet engines is a main engine, and the first jet engine and the second jet engine are mounted to an airframe and intersected by a plane vertical to a centerline along the longitudinal axis of the airframe; (b.) during take-off and climb, running the first jet engine and running the second jet engine; and (c.) during ordinary operational cruise, running one of the first jet engine and second jet engine and reducing the power of the other jet engine while keeping it running.
