A system includes a reception unit to receive current flight data of the aircraft and current meteorological data, a data processing unit to perform an iterative computation to determine, as a function at least of a set of predetermined rules, of a set of constraints and of current values including current meteorological data, an optimal flight trajectory making it possible to generate a dissipation of the energy of the aircraft to bring it, at a stabilized final position, into a final energy state with a minimum ground distance, the optimal flight trajectory defining positions at which actions must be implemented on the aircraft, and a data transmission unit to transmit at least the minimum distance to at least one user system.

Method and system for assisting in the management of the energy of an aircraft over a minimum ground distance in an approach phase

A method and device for generating an optimum aircraft vertical trajectory, including a unit performing iterative processing to determine, on each iteration, a next state from a computational state, by using an estimated overall cost for next states, each estimated overall cost, which is computed by a cost computation unit, being equal to the sum of a real cost computed up to the next state under consideration by using predetermined constraints and a cost estimated up to the current state of the aircraft. The estimated cost is computed using a deterministic neural network based on performance calculations for the aircraft without using energy constraints, allowing computation of this estimated cost and the estimated overall cost to be performed rapidly. The iterative processing is repeated until the determined state is situated in proximity to the current state of the aircraft, the corresponding trajectory part forming the optimum vertical trajectory.
