Abstract: The general field of the invention is that of aircraft cockpit viewing systems including a piece of human-machine interfacing equipment, a piece of data processing equipment and a viewing device. The piece of data processing equipment comprises a database including a plurality of objects and means for computing various displaying windows, each object having a plurality of forms of graphical representation in said windows. The viewing device is arranged to display the displaying windows. The piece of human-machine interfacing equipment includes means for selecting a state of graphical representation of an object in one of the windows. The states of graphical representation of the objects include a “selected” state. When the selection of a state of graphical representation of an object is effective, the computing means of the piece of processing equipment switch all of the various graphical representations of said object in the various windows to this “selected” state.

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.
