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 of managing the display of an aeronautical map from cartographical data is implemented by an electronic management device and comprises the following steps: acquiring a display scale of the map; determining a set of symbol(s) representative of obstacle(s) to be displayed, the obstacle(s) being included in the cartographical data, where: if the distance between two obstacles is greater than a visible distance threshold that depends on the display scale, two separate symbols are determined for these obstacles, each being representative of a respective obstacle, and if the distance between two obstacles is less than or equal to the visible distance threshold, a symbol representative of a grouping of obstacles is determined for these obstacles.
