Abstract: 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.

Abstract: 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.

Abstract: A method, and an associated device, is provided for the determination, by a flight management system of an aircraft, of a lateral trajectory of said aircraft on the basis of a predefined flight plan allowing consecutive conflicts to be resolved in an improved manner. This allows an improved lateral trajectory to be designed in the case where multiple trajectory conflicts exist. The trajectory obtained is closer to the flight plan defined by the pilot. The propagation of trajectory conflicts to the following flight segments is thus avoided. In fact, instead of propagating the trajectory conflict from one resolution to another, the method allows the conflict to be resolved in a space delimited at most by the input of the first conflict and the output of the last conflict.

Abstract: A method of graphical manipulation of the trajectory of an aircraft comprises the steps of receiving an indication of a deformation point associated with the trajectory of the aircraft; determining a zone of local modification of the trajectory of the aircraft as a function of the deformation point; computing a modified trajectory and graphically restoring the modified trajectory. A parameter associated with the indication of the deformation point, notably a speed and/or acceleration value (for example of the contact point on the touch-sensitive interface, or else of a cursor), is received or determined. A modified trajectory is computed by selecting a computation algorithm from among a plurality of faster or slower predefined algorithms; the selection being performed as a function of the parameter. Various other developments are described (configurable selection, trajectory modification bounds, processing of an arbitrary deformation point, i.e. one other than a point of the flight plan, etc.).
