Abstract: A method for establishing a flight plan for an aircraft by: determining a correction factor F1 related to a degradation in performance of the aircraft; using, to establish the flight plan, a model of the aircraft that incorporates a lower heating value of a reference fuel; obtaining a correction factor F2 related to a difference in lower heating value between the reference fuel and a fuel intended to be used to follow the flight plan; modifying the correction factor F1 by adding the correction factor F2; and determining the flight plan using the model of the aircraft, to which the modified correction factor F1 is given at input. It is thus possible to use an aircraft model in which the lower heating value is fixed internally.

A construction unit is configured to automatically construct a vertical profile for an aircraft descent and/or approach, using the value thus provided.

Abstract: A method and device for automatically determining an optimized approach and/or descent profile for an aircraft are provided. The device comprises means for optimizing an approach and/or descent profile of an aircraft avoiding long and steep geometric segments, the device to this end inserting an idle segment, if it satisfies the restrictions, in the profile relating to the descent phase and/or to the approach phase, wherein said idle segment can be followed by a geometric segment.

Abstract: Method and device for automatically determining an optimized approach profile for an aircraft. The device provides for a flexible configuration change speed which is not limited to the standard single predetermined configuration change speed in order to prevent segments which are not authorized, in particular segments which are too steep, the following configuration (Ci+1) being able to be maintained during a configuration change in an upstream direction until the corresponding speed profile reaches a maximum speed.

Abstract: The invention concerns a method for coding images using selectively at least two image coding modes, each optimising compression of at least a video sequence image on the basis of different optimisation criteria.

Abstract: The invention concerns a method for constructing at least an image interpolated between a preceding image and a following image of an animated sequence. The invention is characterised in that the method takes into account data concerning the presence of at least an occlusion zone in said preceding image and/or in said following image, called occlusion data.
