Claim 0:
1. A method for assisting in a management of an energy state of an aircraft, the energy state representing a total mechanical energy of the aircraft, in an approach phase with a view to a ground landing, said approach making it possible to join a final position at which the aircraft needs to have a final energy state from a current energy state of the aircraft, comprising:
at least one reception step, implemented by a reception unit, comprising receiving current flight data of the aircraft making it possible at least to determine said current energy state, and current meteorological data of the environment of the aircraft, said current energy state based on a current altitude and a current speed of the aircraft;
a set of computation steps, implemented by a data processing unit on the aircraft, comprising performing an iterative computation, backwards from said final position, to determine, as a function at least of a set of predetermined rules, of a set of constraints and of current values including said current meteorological data, an optimal flight trajectory from an initial position, independent of a current position, to the final position making it possible to generate a dissipation of the energy of the aircraft to bring the aircraft, at said final position, into said final energy state with a minimum distance in horizontal projection on the ground, said optimal flight trajectory defining positions at which actions must be implemented on the aircraft;
a data transmission step, implemented by a data transmission unit, comprising transmitting at least said minimum distance in horizontal projection on the ground to at least one user system; and,
guiding the aircraft to the final position Pf with the final energy state along the optimal flight trajectory with at least one of manual piloting, automatic piloting in a selected mode, and automatic piloting in a managed mode.
