Zusammenfassung:	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.
