A color key can be displayed by
moving the Joystick Pointer and
pressing the LEGEND Softkey.
Notice there are two legends when
viewing the Relative Terrain Map
Display. The first page shows the
color key for terrain (Figure 1-18)
and the second (Figure 1-19)
shows the color key for obstacles.
The airplane icon conveys what
colors would be below current air-
craft altitude and what would be
above. The airplane icon itself,
however, does not represent current aircraft altitude. Press the NEXT
and PREV Softkeys to toggle between the two displays. To exit, press
the CLEAR Softkey then press the RESET STICK Softkey.
Figure 1-20 depicts obstacles displayed on the Relative Terrain Map.
Note the differences in color between terrain and obstacles based on an
aircraft altitude of 2,000 ft MSL. Obstacles are enhanced on the Relative
