VIEWING DEVICE FOR AIRCRAFT COMPRISING RADIO NAVIGATION BEACON DISPLAY MEANS AND ASSOCIATED METHOD
First Claim
1. Viewing system of synthetic vision SVS type, comprising at least one navigation database, a cartographic database of a terrain, position sensors, a radio navigation beacon sensor, an electronic computer, a human-machine interface means and a display screen, the computer comprising means of processing the different information obtained from the databases, from the sensors and from the interface means, said processing means arranged so as to provide the display screen with a synthetic image of the terrain including a representation of the beacons present on said terrain, wherein the beacons present beyond a first distance from the system are not represented, the beacons present at a distance between said first distance and a second distance less than the first distance are represented in symbolic form, the beacons present at a distance less than the second distance are represented in physical form.

Abstract
The general field of the invention is that of viewing systems of synthetic vision SVS type, comprising at least one navigation database, a cartographic database of a terrain, position sensors, a radio navigation beacon sensor, an electronic computer, a human-machine interface means and a display screen, the computer comprising means of processing the different information obtained from the databases, from the sensors and from the interface means, said processing means arranged so as to provide the display screen with a synthetic image of the terrain including a representation of the beacons present on said terrain. In the system according to the invention, the beacons present beyond a first distance from the system are not represented, the beacons present at a distance between said first distance and a second distance less than the first distance are represented in symbolic form, the beacons present at a distance less than the second distance are represented in physical form.
