Abstract

A traffic information display format, situated in a craft, for observing traffic in a volume about the craft, having one or more viewing grids that display traffic on the display in a three-dimensional perspective so that the observer of the display can conceptually and immediately perceive the traffic entities and their statuses, distances, altitudes, ascending rates, descending rates, closing rates, receding rates and other information. The formats are generated by situation and symbol computers and provided to a stroke or flat panel display. The computers follow a system flow design that results in symbol and format generation for a display.
