SYSTEM AND METHOD TO ASSIST IN THE BRAKING OF AN AIRCRAFT ON A LANDING RUNWAY
First Claim
1. A method to assist in adjusting the braking intensity of an aircraft on a landing runway comprising the steps of:
- recovering data concerning the aircraft or concerning the runway where the aircraft is landing;
acquiring the position of the aircraft on the runway and its speed in the taxiing phase;
calculating the distance that the aircraft will have traveled on the runway when the aircraft has reached a certain speed and/or the speed that it will have reached when the aircraft has traveled a certain distance, the distance and/or the speed being calculated assuming that the speed of the aircraft decreases according to a predefined time function;
wherein the position characterizing the start or the end of the runway and the length of the runway are recovered in the data recovery phase and the distance that the aircraft will have traveled on the runway when it has reached a zero speed is calculated in the calculation phase, the limitation of the difference between the calculated distance and the distance remaining to reach the end of the runway allowing the braking intensity to be increased or reduced.

Abstract
A system includes a means of acquiring the position of the aircraft on the runway and its speed in the taxiing phase, a means of storing data concerning the runway and a predefined deceleration law, a function for calculating the distance that the aircraft will have traveled on the runway when it has reached a certain speed and/or the speed that it will have reached when it has traveled a certain distance: the calculated distance makes it possible to adapt the braking by comparison with the distance remaining to reach the end of the runway; the calculated distance makes it possible to adapt the braking by comparison with the distance remaining to reach the end of the runway; the calculated speed makes it possible to adapt the braking by comparison with the maximum speed to take the exit.
