Abstract
The disclosure of this invention pertains to a system for optimizing fuel consumption in an aircraft having two engines, wherein a computer is programmed to increase the fuel flow to the engine which, consequent upon a fuel flow perturbation, shows itself to be responsible for the greater acceleration of the aircraft. Direction changes resulting from unequal fuel flows to the engines are compensated for by automatic rudder control, and speed changes resulting from the fuel flow changes are compensated for by automatic speed control also acting on fuel flow, all whereby direction and speed of flight are maintained while fuel consumption is minimized.
