Abstract: 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.

Abstract: A method for generating an optimum vertical trajectory of a flight trajectory of an aircraft in the descent/approach phase. The trajectory is defined between a current state and a target state of the aircraft on the basis of a speed profile of the aircraft as a function of a curvilinear abscissa of the aircraft along a flight plan. The profile corresponds to a transition between the current and target states and is broken down into successive segments each corresponding to a different aerodynamic configuration that the aircraft may adopt during the descent/approach phase. The method is based on defining a set of flight strategies, each strategy of the set being defined using for each segment of the speed profile flight parameters chosen randomly in ranges of values compatible with the aerodynamic configuration corresponding to that segment. Optimum vertical trajectory is generated on the basis of the strategy of the set.

Abstract: In operating an aircraft, a situation is displayed at each instant representing a spatio-temporal overview of risk zones around the aircraft. Each direction in space around the aircraft is scanned, and a simulated displacement of the aircraft in each direction is analyzed so as to identify potential zones of interference with the aircraft's path. Anticipated movement of risk zones over a planned time duration of a flight is determined. Such anticipated movement is correlated with an anticipation position of the aircraft over the planned time duration. Accordingly, risk zones initially appearing as a potential hazard may be determined to be safe by the time the aircraft reaches them, and vice versa. Such information is presented to pilots at an outset of the flight and continuously updated throughout the flight, enabling accurate and safe evaluation and strategy decisions.

Abstract: An aircraft with a unit to transmit information on ability/inability of pilots to fly the aircraft. Guidance avionics include guidance architecture and a flight controller to fly the aircraft. The guidance architecture has two dissimilar guidance chains and a selection unit connected thereto, to the flight controller and to the unit for measuring physical ability/inability, a first guidance chain to compute a main path for the aircraft towards a destination airport based on a current state of the aircraft by following a flight plan and to compute main guidance instructions for following the main path, a second guidance chain to compute an emergency path for the aircraft towards a diversion airport based on an initial portion of the common path with the main path and to compute emergency guidance instructions for following the emergency path. The selection unit receives the main and emergency guidance instructions and transmits either one to the flight controller.
