TREDIMENSJONALT PERSPEKTIVISK PLANRISSFORMAT FOR SITUASJONSVITEN-FREMVISNINGER.

摘要

A three-dimensional perspective plan-view image format (20) for a traffic situation awareness display for a craft, has the craft represented by a center symbol (28) that indicates by its shape the horizontal heading of the craft, has traffic represented by position symbols (34) with lines (30) indicating altitude differentials having traffic end symbols (35, 36, 37) that indicate by various properties (i.e., shape, color or fill pattern) the directions of altitude changes of the traffic, has rings (38) concentric to and individually equidistant from the center symbol (28) for indicating the ranges of the traffic from the craft, has azimuth lines (24) emanating like spokes out from the center symbol (28) for determining azimuths of the traffic relative to the craft, and has various properties in the symbols (35, 36, 37) to indicate status and other information about the traffic. The center symbol (28), position symbols (34), range rings (38) and azimuth lines (24), except the altitude differential lines (30) with associated traffic end symbols (35, 36, 37), are within one reference plane (26), representing the altitude of the craft, that is tilted in the display towards the viewer for providing a three-dimensional perspective.
