Abstract

The present system automatically stabilizes the travel direction of an aircraft rolling out after touchdown on a runway. A corrected difference control signal is supplied to the steering mechanisms of the aircraft, including, if desired, the brake system. The control signal is generated in a comparator or transducer which receives at its inputs an actually measured signal representing changes in the travel direction of an aircraft, and a rated signal to produce a combined steering signal which is supplied to the nose wheel steering and/or to the wheel brakes.
