Abstract

A method for creating a vertical trajectory profile of an aircraft by optimization of a criterion representative of a flight cost, comprises: performing a first iterative computation of a profile free of altitude constraints as long as a condition dependent on the criterion is not reached, replacing each free level of the constraint-free profile with a permitted level so as to generate an initial constrained profile comprising a plurality of permitted levels, and, for each level, an altitude change point and a plurality of speeds, and performing a second iterative computation of a profile in which the altitude levels to be reached remain constant, equal to the initial permitted levels of the initial constrained profile, as long as a condition dependent on the criterion is not reached.

First claim

The invention claimed is:

1. A method for creating a vertical trajectory profile of an aircraft by optimization of a criterion representative of a flight cost in a computer of a flight management system or of an electronic flight bag, a trajectory being computed from an ordered list of waypoints contained in a flight plan, a vertical profile associated with the trajectory being defined by a plurality of successive altitude levels to be reached by the aircraft for each level:
an al…
