Aircraft stop-to-position autobrake control system
First Claim
1. An aircraft automatic braking system comprising:
- (a) stop position input means for selecting a desired aircraft stopping position on a runway;
(b) an aircraft positioning system for determining the aircraft'"'"'s present position; and
(c) control means for continuously comparing the aircraft'"'"'s actual position with said selected stopping position and, in response thereto, predeterminedly decelerating said aircraft such that the aircraft tends to stop at said selected position.

Abstract
An aircraft automatic braking system processes the flight crew selected stopping position of the aircraft on the runway via a control display unit (30) and the aircraft'"'"'s actual position, provided by a global positioning system (34), to generate a stop-to-position deceleration control signal in a provided control logic (36). If the flight crew selects the stop-to-position autobraking mode, the system determines whether or not a stop-to-position autobraking mode meets several predetermined criteria and, if the criteria are met, applies a control signal to the aircraft'"'"'s braking system (62, 66) such that the aircraft is smoothly braked tending it to stop at the selected runway stopping position. The system eliminates the need for pilot lookup in a manual to determine a desired autobraking setting to choose based on altitude, temperature, approach speed and runway conditions and also operates to reduce pilot workload during limited visibility conditions.
