Abstract: Methods and systems for managing the orientation of the display of an aeronautical chart, notably towards Magnetic North or True North are provided. Rotational and/or translational tactile movements may manage the display of the chart. In one advantageous embodiment, the display screen is a haptic feedback screen (for example piezoelectric or MEMS microactuators), the North symbol rendered in relief is able to be manipulated with a single finger and the display device is stabilized by at least partially compensating for the turbulence experienced by the cockpit. Some software aspects are described.

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.
