Abstract: A method for assisting an aircraft in landing on a runway and an associated system includes determining a target exit point from the runway and a target taxi speed at which the aircraft has to take the target exit; calculating a target ground distance representative of a ground deceleration phase; and calculating the position of a target touchdown point on the basis of the target ground distance. The target ground distance is calculated as a function of a target deceleration profile for the aircraft to reach the target exit point at the target taxi speed.

Abstract: A dynamic determination method for determining the position of a stopping point of an aircraft on a landing strip and related system includes determining a first table of average time from touchdown of the aircraft as a function of the ground speed, based on an average deceleration profile of the aircraft; determining a first deceleration profile adapted to the current conditions, based on an engine thrust computed for each ground speed from the average time determined in the first table; determining a second table of time adapted to the current conditions based on the first deceleration profile; determining a second deceleration profile adapted to the current conditions, based on an engine thrust computed for each ground speed from the time determined in the second table; and computing the position of the stopping point from the second adapted deceleration profile.

Abstract: A method to control braking of an aircraft on a landing runway including: selecting a dummy runway state corresponding to a level of adhesion of wheels of the aircraft to a runway which is lower, over an entire speed range of the aircraft while braking on a runway, than an adhesion level of the wheels of the aircraft to the landing runway; calculating a set point of a deceleration value for the aircraft on the landing runway based on the landing runway for the selected dummy runway state, wherein the calculated set point corresponds to maximum braking value of the aircraft, and controlling the braking of the aircraft using the set point.
