Abstract
A system and method for displaying a three-dimensional image of airspace includes a series of translucent, horizontal “pavers” that lie like stepping stones marking the selected flight path. In addition, the display includes a series of vertical rectangles—called “wickets”—which bracket the selected flight path. One or more of the wickets may include a graphical representation of the direction of the aircraft should be flying through the wicket. The system accommodates changes in course by generating a new flight path when instructed to do so. The new flight path is created in a way that assures continuous guidance for the pilot and sufficient time for the pilot to adjust to the new course. The display can include a compass rose which indicates the aircraft's present heading and direction of flight. The compass rose is generated from data representing a traditional two-dimensional view of a compass rose that is rotated using a graphics processor to show a three dimensional view of the compass rose in a plane that appears nearly horizontal in the three dimensional airspace image. In addition various landmarks such as airports and navigation beacons, as well as geopolitical boundarie…
