Abstract:
A method for displaying advanced information on a host aircraft display, the method comprising:displaying an icon representing another aircraft within a predetermined range; delineating said icon; displaying a first visual symbol describing a relative velocity of the other aircraft; and displaying a second visual symbol describing a wake vortex created by the other aircraft, wherein said second visual symbol further comprises visual symbology describing location and intensity information that is prepared by a process comprising the steps of; a) collecting position of the other aircraft relative to host aircraft; b) collecting weight class and aircraft type information of the other aircraft; c) collecting barometric elevation above mean sea level of the other aircraft; d) collecting terrain elevation information; e) determining elevation of the other aircraft based on position information of the other aircraft in combination with said terrain elevation information, f) collecting local runway information from a database of airport information; g) collecting predicted configuration of the other aircraft; h) collecting local wind information; i) collecting local temperature; and j) determining an estimate of the severity, extent, and drift of said wake vortex.
