Abstract
The method for reducing aircraft carbon brake wear involves monitoring the commanded initiation of braking, and setting a residual brake clamping force to a predetermined minimum residual brake clamping force, which is maintained following the commanded initiation of braking to prevent release of braking during taxiing of the aircraft. The minimum residual brake clamping force is applied despite a commanded release of braking until at least one predetermined control logic condition occurs.
Claims6
A method for controlling carbon brakes of an aircraft having a plurality of wheels and a corresponding plurality of wheel brakes for the plurality of wheels to reduce brake wear when the aircraft is taxiing, comprising the steps of:
- monitoring commanded initiation of braking of any of the plurality of wheel brakes of the aircraft;
- and
- applying a predetermined minimum residual brake clamping force to the plurality of wheel brakes in response to said commanded initiation of braking of any of the plurality of wheel brakes despite a commanded release of braking of any of the plurality of wheel brakes until a control logic condition occurs, said control logic condition being selected from the group consisting of said plurality of wheels having average wheel speed below a predetermined wheel speed threshold, an engine thrust lever being in an advanced position, a wheel speed acceleration exceeding an acceleration threshold, and a temperature of said plurality of wheel brakes exceeding a temperature threshold.
