System and method for aircraft braking system usage monitoring
First Claim
1. A system for monitoring wear of an aircraft part, comprising:
- at least one sensor for sensing a parameter of usage of an aircraft part and for generating a signal indicating a sensed value of said parameter of usage of said aircraft part;
means for measuring a period of time elapsed during each usage of said aircraft part and generating an elapsed time signal; and
means for determining an estimate of usage of said part based upon said elapsed time signal and said signal indicating said sensed value of said parameter of usage of said aircraft part.

Abstract
The system and method for monitoring wear of one or more aircraft parts, such as an aircraft brake, an aircraft tire, a standby system, and landing gear. One or more sensors are provided for sensing a parameter of usage, and an estimate of usage of the part can be determined based upon the signal indicating the sensed value of the parameter of usage of the aircraft part. A plurality of sensors can be provided for sensing usage of a plurality of parts of the aircraft, and the estimate of usage of the part can be stored for access of the estimate by ground personnel. As applied to monitoring wear of an aircraft brake, a linear brake wear indicator attached to the brake moves a discrete distance when the brake is actuated, and a linear position encoder measures the distance travelled by the linear brake wear indicator as an indication of brake usage. A wheel speed monitor may also be provided for measuring the aircraft wheel speed, for distinguishing between static brake applications and moving brake applications, based upon the wheel speed signal.
