Abstract
An automatic fore/aft detection procedure as described herein may be implemented in connection with an aircraft brake control system that utilizes wheel-mounted accelerometers that detect landing gear acceleration for purposes of antiskid control. The fore/aft detection procedure automatically determines that the aircraft is moving in a forward direction based upon the current wheel speed and rotational direction of the wheels. Once detected, forward direction is assigned to the rotational direction of each wheel (clockwise or counterclockwise) and a fore/aft orientation can be assigned to the accelerometer for each wheel.
