Method for piloting a vehicle while making a change of heading. The vehicle follows a first rectilinear portion of a route, so as to meet up with a second rectilinear portion of the route forming a predetermined angle with the first portion. The route passes through the meeting point of the two portions. The vehicle computes and follows a curved change of heading trajectory which passes through the meeting point whose turning center lies on the interior bisector of the angle formed by the two portions of the route.

Method for controlling a vehicle in order to change course and application of method for the lateral avoidance of a zone

The disclosed method is implemented by a system aboard an aerodyne comprising a processor, a terminal and memories in which there are stored all the information necessary for the carrying out of a flight, the system being connected to the other on-board electronic equipment. In order to define a new flight plan to meet a new situation caused by an event, the method comprises: the interpretation of the event to determine the corrective actions to be undertaken given the context in which the aerodyne is located, the analysis of the possibilities of reconfiguring the flight plan that correspond to the corrective actions, according to predetermined and modifiable criteria, the selection of the flight plan solutions that meet the predetermined criteria, and the presenting of these flight plan solutions in association with the significant parameters that have served as the grounds for their selection.

Method of assistance in the piloting of an aerodyne

A method for laterally avoiding a fixed zone in an aircraft. The contour of the zone to be avoided is modeled by a convex polygon shape. The planned route is located with respect to the modeled zone. The port and starboard sections of the route for exit and return of the planned route are computed. A predetermined angle is formed which meets with a corner point of the contour to obtain two avoidance routes formed by the exit and return sections of the route and by the portions of the contour. One of the two avoidance routes is then selected.
