Abstract: A method implemented by computer for the management of the descent of an aircraft, comprises the steps of: receiving a descent profile; determining a search band comprising a plurality of flight segments of the profile; and selecting a flight segment in the search band. Various selection criteria are described, in particular the consideration of the commands of pitch-up and/or separation with respect to the active segment (anticipation distance). Other developments comprise the fact that the search band is configurable, the consideration of the load factor, modalities of tangent capture (trajectory with no segment crossing), compliance with altitude constraints, the determination of capture parabola modeling the trajectory, as well as the activation of the segment selected as control reference. System aspects and software aspects are described.

Abstract: A method for determining a switch-over vertical point from which an aircraft, having a current position, and flying a current vertical trajectory according to a manual piloting mode having an altitude setpoint, denoted target altitude, loaded by the pilot, switches to a piloting mode guided by a flight management system, in order to rejoin a predefined flight plan having a set of initial altitude constraints, comprising: calculating a first predicted vertical trajectory, determining a first point of intersection between the first predicted trajectory and the target altitude, determining a second predicted trajectory, determining the switch-over vertical point belonging to the first predicted vertical trajectory, based on any incompatible constraints, and as the intersection between the first predicted vertical trajectory and a predicted vertical trajectory calculated by integration of the dynamic flight equations by applying calculation hypotheses for a piloting mode guided by a flight management system.
