A method for aiding navigation is provided, implemented in a flight management system, for the construction of a vertical trajectory of an aircraft following a predetermined lateral trajectory between a departure point and an arrival point; the departure point and arrival point furthermore being characterized by predefined altitudes, respectively H d and H a , and predefined speeds, respectively V d and V a . The method comprises the steps of: selection of a transition manoeuvre in terms of altitude and speed from a predetermined list of manoeuvres; determination of a manoeuvre point P M on the lateral trajectory, of altitude H d and of speed V d , from which the transition manoeuvre must be initiated so as to allow the aircraft to reach at the arrival point the predefined speed V a and the predefined altitude H a . |
