US Patent 7407133 Using imbalanced thrust in a multi-engine jet aircraft

Methods of operating a multi-engine jet-aircraft. According to one embodiment of the present invention, a first jet engine and a second jet engine are provided. One of the jet engines has a lesser maximum thrust capability than the other jet engine as a result of limiting the former's maximum thrust capability, but the two jet engines are otherwise equally powered. During various segments of flight, both the first jet engine and second jet engine are utilized. A thrust differential between the first jet engine and the second jet engine is created during one or more flight segments by continuing to run either the first jet engine or second jet engine, but running the other at a reduced power.
