Deceleration Feedback System and Algorithm

Abstract

A deceleration feedback algorithm for an aircraft braking system is provided. The algorithm prevents the aircraft brakes for releasing to clearance during a braking operation, while maintaining differential pilot/co-pilot braking inputs. The method and system determine an actual rate of deceleration of the aircraft and calculate the required rate of deceleration of the aircraft, thereafter making a comparison of the actual and required rates of deceleration. It then controls the application and release of brake pressure to the right and left brakes of the aircraft as a function of that comparison, while precluding the discs of the heat stacks from going into separation as a consequence of non-braking activities. Additionally, a minimum brake pressure is provided, ensuring the capability of differential braking between the right and left brake pedals and associated right and left brakes.
