A method is provided for adjusting a flight plan rejoining trajectory of an aircraft, the method being implemented in a flight management system of the aircraft. In a first step, the rejoining trajectory comprises a guidance setpoint holding point to be reached situated in the extension of a guidance setpoint, and set manually or automatically, the guidance setpoint no longer being necessarily maintained when this setpoint holding point is passed. This first step can be preceded by a step of rejoining a guidance setpoint or a step of searching for the intersection of the current guidance setpoint trajectory with a segment of the flight plan.

Rejoining trajectory adjustment method for aircraft

A method for automatically calculating a trajectory for an aircraft to re-join a reference route of the aircraft executed iteratively, in particular when the aircraft is no longer locked onto its reference route, each iteration comprising a step of detection of deviation from the active segment of the route; if the deviation from the active segment of the route is detected, the method comprises a step of selection of a route segment to be re-joined, a step of calculation of a re-joining trajectory between a starting point and the route segment to be re-joined, and a step of validation of the trajectory of the route segment to be re-joined. Where this trajectory is validated, the method comprises a step of assignment of the re-joining trajectory for the segment to the re-joining trajectory for the route. Otherwise, it comprises a step of verification of the existence of a next route segment fulfilling a selection condition. If a next route segment fulfils a selection condition, it comprises a step of selection of the next route segment as route segment to be re-joined, and a return to the step of calculation of a re-joining trajectory for the route segment to be re-joined. If no route segment fulfils the selection condition, it comprises a step of application of an exit procedure. A computer program for implementing this method is provided.

Flight management device for an aircraft adapted to the handling of multiple time constraints and corresponding method

A method is provided for guaranteeing a temporal spacing between an aircraft and at least one reference moving object, said spacing needing to be guaranteed no later than at a point in the flight plan called the point of interception, with the aircraft following a current flight plan. The feasibility of guaranteeing the spacing at a date Tcour by regulating the speed of the aircraft while maintaining the current flight plan is verified in a first step. In a second step it is verified whether the date Tcour is contained within a feasibility range. In a third step the current flight plan is modified when the feasibility is not verified, a lateral trajectory between the current position Xcour of the aircraft and the point of interception being implemented in this case such that the spacing can be attained by regulating the speed.

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.

A method of optimizing a flight plan of an aircraft used in a flight management system of an aircraft is disclosed. This method makes it possible to constrain the real cost index of the mission executed to the optimal cost index CIpredetermined by the aircraft operator, by acting on objectives ETAand EFOBof values of ETA and of EFOB to be achieved. Objectives are linked to this optimal cost index, in order to make the system return from a cost index CIto the optimal cost index CI, while taking account of various constraints imposed by the ATC or the CTFM. Both constraints minfluence the cost index and constraints which limit the field of possible solutions.

Method for managing the flight of an aircraft

The present invention relates to a method for changing the path followed by an aircraft, the aircraft initially following a predefined path on the basis of a sequence of waypoints, the method allowing a subsequent return of the aircraft to the predefined path in the same direction or in the reverse direction. The method allows a possible return of the aircraft to the predefined path in the same direction such that the waypoints of the predefined path are projected onto a new path according to a projection function ensuring that the order of the sequence of the projected image points complies with the order of the sequence of the original waypoints. The projection of a waypoint already reached by the aircraft also is considered as having been reached. The projections of the waypoints on the new path are considered reached by the aircraft progressively as the latter progresses along the new path. The aircraft eventually rejoins the predefined path at the first waypoint in the order of the sequence of points whose projection is not yet considered as reached on the new path.
