Abstract

Procédé d’affichage sur un écran d’affichage d’une vue synthétique tridimensionnelle, produit programme ordinateur et système d’affichage associés L’invention concerne un procédé d’affichage sur un écran d’affichage dans un poste de commande d’un aéronef comprenant des bases de données comportant chacune des données cartographiques représentatives d’éléments du terrain avec une résolution respective. Le procédé comprend les étapes suivantes : - acquisition d’une altitude maximale du terrain et d’une altitude de l’aéronef ; - calcul d’une distance de visibilité (D) et d’une résolution cible en fonction de la hauteur entre l’altitude maximale et l’altitude de l’aéronef ; - test de la convenance de la base de données cible ; - si la base de données cible convient, détermination de la vue synthétique tridimensionnelle à partir des données cartographiques de la base de données cible ; et - affichage de la vue synthétique tridimensionnelle de la zone du terrain sur l’écran d’affichage. Figure pour l'abrégé : Figure 3Method for displaying on a display screen a synthetic three-dimensional view, computer program product and associated display system The invention relates to a method for displaying on a display screen in a control station of an aircraft comprising databases each comprising cartographic data representative of elements of the terrain with a respective resolution. The method comprises the following steps: - acquisition of a maximum altitude of the terrain and an altitude of the aircraft; - calculation of a visibility distance (D) and a target resolution as a function of the height between the maximum altitude and the altitude of the aircraft; - test of the suitability of the target database; - if the target database is suitable, determination of the three-dimensional synthetic view from the map data of the target database; and - display of the synthetic three-dimensional view of the area of the pitch on the display screen.
