<p>A system and method for displaying a three-dimensional image of airspace includes a series of translucent, horitontal '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 away 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 boundaries may be included in the display.</p> |
