Terrain Awareness Upgrade
For AirMap2000
This Terrain Awareness upgrade allows
your AirMap 2000 to show the ground in
color shaded relief format, and uses different
colors to highlight terrain with potentiall
y
hazardous altitudes. The topography is rep-
resented by dark green, dark yellow and
brown. Terrain awareness is represented b
y
light green, yellow and red highlights.
The software upgrade comes loaded on an
MMC or SD card. It also contains the latest
JeppesenAmericas and Lowrance Ob-
structions aeronautical databases, the ter-
rain mapping data and airport taxiwa
y
mapping data. The terrain data includes
high resolution maps for North and South
A
merica and lower resolution maps for the
rest of the world.
Y
ou must have the terrain awareness car
d
inserted in the unit in order to use the ter-
rain awareness features
Installation
The software upgrade will not run if the
batteries in your AirMap 2000 are low. We
recommend you run the upgrade with the
unit attached to external power. If you're not
using external power, make sure the batter-
ies are fresh before beginning the upgrade.
1. Insert the upgrade card into the AirMap.
2. Connect the unit to external power. 3.

2
Turn the unit on, and the upgrade begins
automatically.
Operation
The Terrain Awareness feature can be
turned on and off in the Map Categories
Drawn menu by checking (on) or uncheckin
g
(off) the Terrain Awareness category. If you
turn off the Background subcategory, the
map screens will not show shaded relief. I
f
you turn off the Warnings subcategory, po-
tentially hazardous terrain will not be high-
lighted in various colors.
Color Code
A
s you fly, the AirMap notes your curren
t
altitude and the height of the terrain below
you. The relief map shows areas with differ-
ent risk levels in different colors, accordin
g
to the following perimeters:
•Red highlight: indicates terrain that is at
your current altitude or higher.
•Yellow highlight: indicates terrain 500
feet below your current altitude.
•Green highlight: indicates terrain 1,000
feet below your current altitude.
•When flying over the ocean, the surface
shading in the Profile Window reverts to a
pattern of small Xs, indicating no risk o
f
flying into elevated terrain.
A
ll map screens will show the terrain relie
f
shading except for the Navigation Panel and
the Aviation Map option. On those screens,
the terrain awareness color highlight does
appear.

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.
Y
ou can use the cursor to view the terrain in
other areas on the map. As you move the
cursor, the projected track line will swin
g
around, leading the cursor. The 2D displa
y
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

information in this display are not as accu-
rate as the position information.
The terrain appears in cross-section at the
bottom of the window. The terrain is color
coded to indicate the relative elevation below
you. Obstacles are represented by a line
extending into the air, with a circular callout
at the top of the line. The callout shows
proximity to your track: an X indicates the
obstacle is on your track or within 500 feet o
f
it; an L indicates the obstacle is more than
500 feet to the left of your track, an R indi-
cates the obstacle is more than 500 feet to
the right of your track.
