Abstract: A method for managing the display of a vertical flight profile of an aircraft includes: determining a deviation between a predefined lateral trajectory and the current position of the aircraft projected in the plane of the trajectory; as a function of at least the determined deviation, selecting a display mode of the vertical flight profile from among a first mode and a second mode. When the first mode has been selected, calculating the distance between the orthogonal projection of the current position of the aircraft on the trajectory and the orthogonal projection of the next waypoint on the trajectory, and displaying, in the vertical flight profile, the next waypoint at a distance from the aircraft along a reference axis equal to the distance. When the second mode has been selected, calculating the distance instead from the current position of the aircraft in the plane of the trajectory.

Abstract: This method for managing the display of a field map for an aircraft is implemented by an electronic device and comprising the following steps: acquiring a reference altitude of the aircraft, using an automatic mode in which the reference altitude depends on a current altitude of the aircraft or a manual mode in which the reference altitude depends on an altitude value entered by a user via an entry interface; determining cartographical element(s) based on the reference altitude; and generating the field map. During the acquisition step, the manual mode is activated if an interaction by the user with the entry interface is detected, and the automatic mode is activated if no interaction with said interface is detected, and this step includes switching to the automatic mode if a switching condition is met.
