A system comprising an adjustment unit installed in an aircraft and configured to adjust a descent trajectory and associated prediction calculations as a function of an adjustment parameter. The system comprises information processing units for automatically calculating, on the ground and from recorded flight data, an effective value of a calculation parameter, and a corresponding theoretical value of the calculation parameter, with the help of an auxiliary performance database which is identical to a performance database installed in the aircraft, for identical flight conditions, and for deriving therefrom the adjustment parameter that will be used subsequently by the adjustment unit.

Method and system for adjusting the descent trajectory of an aircraft

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.

Method and device for automatically determining an optimized approach and/or descent profile

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.
