1. A system for managing a deceleration of an aircraft on a runway on the ground enabling a control in real time of a position of the aircraft on a braking axis of the runway, comprising:
a braking system configured to brake the aircraft;
a calculator configured to:
calculate, from aircraft data and from external data comprising data on a state of the runway and meteorological data on the ground, a sequence of use of the braking system of the aircraft on the ground intended to brake the aircraft along the braking axis, over a predetermined braking distance associated with a predetermined braking duration comprising a plurality of braking instants each associated with a predetermined position on the braking axis, the sequence of use of the braking system being defined as an ordered series of use of the braking system between a landing point and a parking point of the aircraft, comprising activation/deactivation of the braking system and its characteristics of use;
update in real time, the sequence of use as a function of the difference, along the braking axis, between the position of the aircraft and the predetermined position associated with a given braking instant, or the occurrence of a given event;
a controller configured to control the braking system as a function of the sequence of use or an instruction sent by a runway overrun alert system of the aircraft.
