The present invention relates to a method of decoupling the mode of automatic following of the lateral profile and the mode of automatic following of the vertical profile of an automatic guidance system of an aircraft (A) flying on a reference trajectory (T). The mode of automatic following of the vertical profile is not disengaged immediately on disengaging the mode of automatic following of the lateral profile. After disengaging the mode of automatic following of the lateral profile, the mode of automatic following of the vertical profile is disengaged automatically only if at least one criterion of lateral separation between the current or short-term position of the aircraft and the lateral profile corresponding to the reference trajectory is satisfied, having regard to the position error.

The invention relates to a device for formulating a flight plan ensuring sufficient safety margins for a duration of a few minutes in relation to the set of flight constraints that could arise and comprising means for: detecting the surrounding moving objects (aircraft or meteorological phenomena), evaluating their type and the danger that they represent, formulating a reconfiguration flight plan ensuring a separation with these phenomena and taking best account of the constraints of the initially followed flight plan, avoiding prohibited or regulated airspaces and avoiding the surrounding relief with ad hoc operational margins.

A method is disclosed for plotting a trajectory portion (6, 6″), using flight management means of an aircraft, and linking a known position (7) of the aircraft to a point in space (4), denoted the “exit point”. A circular arc is defined, the coordinates of whose centre (1) are known, comprising two ends (3, 4) of known coordinates, one end of which is the exit point (4). The position of a transition point (5) is determined which is situated on the arc. The trajectory (6, 6″) by the flight management means of the aircraft is automatically plotted. The trajectory is successively linking the known position (7) of the aircraft, and the transition point (5) and the exit point (4).

The invention relates to a method for formulating the strategy of an aircraft, with a view to favouring adherence to a time constraint.With this aim, the method according to the invention consists in optimizing the margin available for the formulation of the aircraft's speed strategy, by calculating a first target required time of arrival (RTAtarget) which is higher, respectively lower, than the required time of arrival (RTA), in the case where said required time of arrival (RTA) is greater, respectively less, than the mean estimated time of arrival (ETAmean). According to the invention, the first target required time of arrival (RTAtarget) is used for the formulation of the aircraft's speed strategy. According to the invention, a second target required time of arrival (RTAtarget2) can be determined subsequently, and used for the formulation of the speed strategy, with the aim of utilizing the margin, previously optimized, available for the formulation of the aircraft's speed strategy.
摘要:
A method for providing for the optimized regulation of the relative spacing between aircraft is disclosed. This method can be implemented by a system whose physical architecture can rely mainly on existing computers on board most current aircraft. The method includes a main step of determining the changing trend of the relative spacing, in distance or in time, between a target aircraft (C) and a following aircraft (S).

A method of applying a “Heading Then Merge Behind” (HTMB) guidance directive sent by an air traffic control center to an aircraft comprising a flight management system, the flight management system making it possible to automatically follow the trajectory of an active flight plan. The method includes reception and validation of the directive by the flight management system, confirmation by the pilot of the aircraft of the application of the directive, creation by the flight management system of a flight plan incorporating the directive, activation by the pilot of the flight plan incorporating the directive, so that the directive is executed automatically by the flight management system while following the trajectory of the flight plan incorporating the directive.
