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 boundaries may
be included in the display.
