Abstract
A method and apparatus for improving fuel efficiency in an aircraft having a digital avionics system and at least first and second engines. The avionics system includes first and second full-authority digital engine control (FADEC) systems and corresponding first and second engines. At least one processor is provided that is programmed with a differential specific fuel consumption (DSFC) algorithm and first and second engine optimization algorithms. The DSFC algorithm adjusts the throttle of the first and second engines to substantially equalize the differential specific fuel consumption of the engines and thereby improve the fuel efficiency of the aircraft. The first and second engine optimization algorithms adjust at least one operating parameter of the first and second engines respectively to improve the fuel efficiency of the first and second engines.
