  • Patent number: 10417919
    Abstract: Systems and methods that optimize landing performance are provided. The system determines a number, N, of equipment configurations (a combination of a brake setting and a thrust reverser configuration) supported by the aircraft. The system determines a deceleration airspeed to achieve a target taxi speed and, for each of the N equipment configurations, determines a respective deceleration distance. In various embodiments, the system further updates the deceleration distances by one or more of a brake's condition, aircraft historical data, brake warranty and life cycle data, and environmental conditions. The deceleration distances are used to identify a number P of exit-ways that can be used at the runway. Total costs (including brake usage and fuel cost) for each of the P exit-ways is determined, and the equipment configuration that delivers the lowest total cost delivers the optimize landing performance.
