Abstract
A fault detection system for an aircraft braking system including: a controller configured to receive braking demand information; torque information; wear information; wheel speed information; and brake temperature information. The controller is to calculate an expected maximum temperature of the brake based on the torque information, the wear information and the wheel speed information; to determine whether a significant temperature discrepancy exists between the expected maximum temperature and the brake temperature information; to determine whether a significant torque-related discrepancy exists based on the braking demand information and the torque information. The controller is to generate a first alert if a significant torque-related discrepancy exists and no significant temperature discrepancy exists; a second alert if a significant temperature discrepancy exists and no significant torque-related discrepancy exists; and a third alert if a significant temperature discrepancy and a significant torque-related discrepancy exists.
