  • Patent number: 11037454
    Abstract: An automatic braking system controller automatically decelerates an aircraft on a runway according to a brake-to-exit or a constant deceleration function. The automatic braking system controller determines whether the aircraft can decelerate to a selected velocity prior to reaching a target location along the runway. In response to determining that the aircraft can decelerate to the selected velocity prior to reaching the target location, the automatic braking system controller automatically decelerates the aircraft with a comfortable deceleration profile such that the aircraft reaches the selected velocity at the target location.

  • Patent number: 10017164
    Abstract: A system, method, and apparatus for brake load alleviation amongst at least one first brake and at least one second brake is disclosed. The method involves sensing an amount of brake pedal application in response to engagement of at least brake pedal. The method further involves determining whether the amount of brake pedal application is greater than a brake pedal application threshold value. Also, the method involves generating a brake application profile, when it is determined that the amount of brake pedal application is greater than the brake pedal application threshold value. The brake application profile indicates that actuation of at least one first brake is delayed by a first time delay, and that actuation of at least one second brake is delayed by a second time delay. Further, the method involves actuating at least one first brake and at least one second brake according to the brake application profile.

  • Patent number: 9139293
    Abstract: Systems, methods, and apparatus for optimizing real-time antiskid control initialization for a vehicle on a travel surface are disclosed. In one or more embodiments, a method involves determining when at least one wheel of the vehicle touches ground. The method further involves calculating a rate of wheel spin up for at least one wheel. Also, the method involves determining whether the rate of wheel spin up exceeds a wheel spin up rate threshold. In addition, the method involves applying a high level of brake force when the rate of wheel spin up exceeds the wheel spin up rate threshold, and applying a low level of brake force when the rate of wheel spin up does not exceed the wheel spin up rate threshold.

  • Patent number: 9082301
    Abstract: A system and method for determining a predicted stopping performance of an aircraft moving on a runway. A predicted stopping force acting on the aircraft to stop the aircraft is determined by a processor unit as the aircraft is moving on the runway. A predicted deceleration of the aircraft moving on the runway is determined by the processor unit using the predicted stopping force acting on the aircraft to stop the aircraft. The predicted stopping performance of the aircraft on the runway is determined by the processor unit using the predicted deceleration of the aircraft.
