Navigation Airspace Page
This upgrade adds the Navigation Airspace
Page to the unit's major operating modes.
This page has two windows. The top window
(Map Window) shows the relief map overlaid
with Jeppesen data and terrain awareness
color shading. The bottom window (Profile
Window) shows your altitude relative to a
2D cross-section of the terrain under and
ahead of you. This window also shows
shading for different airspace categories.
Map Window
In the Map Window, the cross-hatched line
extending from the nose of the aircraft sym-
bol represents your projected track. The area
under this projected track is shown in the
Profile Window below.
You can use the cursor to view the terrain in
other areas on the map. As you move the
cursor, the projected track line will swing
around, leading the cursor. The 2D display
changes according to the selected terrain.
Profile Window
In this window, your current position (or
cursor position if cursor is up) is always at
the left edge of the screen. The terrain ahead
of you stretches to the right. The line ex-
tending from the aircraft nose is your alti-
tude and vertical speed indicator. In level
flight, the altitude line is parallel to the
ground. In a climb, the altitude line will
swing up. It will swing down when de-
scending. Controlled airspaces are shown in
different colors and in the appropriate 2D
shapes. Note that vertical speed and altitude
