Abstract
A system for representing cartographic indications for an aircraft, said system comprising at least a cartographic database, a graphical computer, a display device and means of selecting a scale of the displayed cartographic data by a pilot or user. Each item of cartographic data comprises at least a first symbolic representation associated with a first scale depending on said item of cartographic data. When the selection means select a scale that is larger than or equal to the first scale, the first representation is displayed on the display device and when the selection means select a scale that is strictly smaller than the first scale, the first representation is no longer displayed on the display device. Each item of cartographic data can comprise at least a second symbolic representation associated with a second scale smaller than the first scale, said second scale depending on said item of cartographic data and obeying similar display rules.
