SYSTEM AND METHOD FOR AIRCRAFT BRAKING SYSTEM USAGE MONITORING
First Claim
1. A system for monitoring wear of a consumable component of a landing gear assembly of an aircraft, comprising:
- a wheel speed monitor for generating a wheel speed signal indicating wheel speed of the aircraft;
means for sensing aircraft yaw, and for generating a yaw signal indicating aircraft yaw; and
means for determining an estimate of wear of the component based upon said wheel speed signal and said yaw signal.

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 traveled 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.
