  • Automatic process for the optimum regulation of aircraft fuel flow
    Patent number: 4063072
    Abstract: A method for operating an aircraft at the minimum total flying cost per unit of distance. The fuel cost per unit of distance and the flying time cost per unit of time are calculated at a first fuel flow setting and are added together to obtain a total flying time cost per unit distance. After a predetermined time interval, a second fuel flow setting is entered into the aircraft and a second total flying time cost per unit distance is calculated and compared to the first. The fuel flow setting is again adjusted in the direction of the minimum total flying time cost per unit of distance. This procedure is repeated until the minimum is found, and can be repeated thereafter at specific intervals to assure that the minimum is maintained.
