PROCEDE DE SIMPLIFICATION DE L'AFFICHAGE D'ELEMENTS STATIONNAIRES D'UNE BASE DE DONNEES EMBARQUEE

摘要

The invention is situated in the field of displaying on board an aircraft geostationary elements of the navigation database on a screen having different display resolutions for the purpose of this data display, and its subject is a method for simplifying the display of stationary elements of this onboard database. This method is characterized in that it consists in precalculating a“decluttering”during the process of producing the onboard database by meshing the Earth with a Cartesian grid oriented along the latitudes and longitudes of the Earth, and by allowing only the most pertinent obstacle to appear in each rectangle of this grid.
