Abstract:
A system for monitoring wear of an aircraft brake, comprising:at least one sensor for sensing a parameter of usage of an aircraft brake and for generating a signal indicating a sensed value of said parameter of usage of said aircraft brake, said at least one sensor comprising a linear brake wear indicator and a linear position encoder, said linear brake wear indicator being attached to the brake, wherein each time the brake is actuated, the linear brake wear indicator moves a discrete distance, and said linear position encoder measuring and generating a linear position signal indicating the distance travelled by the linear brake wear indicator as an indication of brake usage; means for determining an estimate of usage of said brake based upon said linear position signal; and a wheel speed monitor for generating a wheel speed signal indicating wheel speed of the aircraft, and wherein said means for determining an estimate of usage receives said wheel speed signal for distinguishing between static brake applications and moving brake applications based upon said wheel speed signal.
