1. A method for managing the display of a vertical flight profile of an aircraft for which a trajectory has been predefined by a flight plan comprising a set of waypoint(s), the method being implemented by an electronic management device and comprising the following steps:
defining the display of a vertical flight profile of the aircraft comprising a first reference axis on the y-axis representing the altitude and a second reference axis on the x-axis representing a distance, and indicating, relative to these axes, the position of the aircraft, and at least the next waypoint along the predefined trajectory;
wherein the method further comprises the following steps:
a predefined lateral trajectory being the predefined trajectory projected in a plane perpendicular to the first axis, determining a deviation between the current position of the aircraft projected in said plane perpendicular to the first axis and the predefined lateral trajectory;
as a function of at least the determined deviation, selecting a mode from among a set of display modes of said vertical flight profile comprising at least a first mode and a second mode; and
when the first mode has been selected, calculating a first value equal to the distance between an orthogonal projection of the current position of the aircraft on the predefined lateral trajectory and the orthogonal projection of the next waypoint of the aircraft on the predefined lateral trajectory, and displaying, in the vertical flight profile, the next waypoint at a distance from the aircraft along the second reference axis equal to the first calculated value;
when the second mode has been selected, calculating a second value equal to the distance between the current position of the aircraft considered in the plane of the lateral trajectory and the orthogonal projection of the next waypoint of the aircraft on the predefined lateral trajectory, and displaying, in the vertical flight profile, the next waypoint at a distance from the aircraft along the second reference axis equal to said second calculated value.
