Terrain Operation

During power-up of the 500W Series unit, the 

terrain/obstacle database versions are displayed along 
with a disclaimer. At the same time, the Terrain system 
self-test begins. A failure message is issued if the test 
fails. 

The Terrain feature is a standard function the 

500W-Series. TAWS is an optional feature and 
information is provided in the 400W/500W Series 
Optional Displays Addendum - p/n 190-00356-30. 

Terrain Proximity displays altitudes of terrain 

and obstructions relative to the aircraft position and 
altitude with reference to a database that may contain 
inaccuracies. Terrain and obstructions are shown 
only if they are in the database. Terrain and obstacle 
information should be used as an aid to situational 
awareness. They should never be used to navigate or 
maneuver around terrain.

Note that all obstructions may not be available 

in the terrain and obstacle database. No terrain and 
obstacle information is shown without a valid 3-D GPS 
position.

To display the Terrain Page, select the NAV 

group and turn the small right knob until the 
Terrain Page is displayed. The page displays terrain 
information, aircraft ground track, and GPS-derived 
MSL altitude. Altitude is shown in increments of 20 
feet or in increments of 10 meters, depending on unit 
configuration. The “G” to the right of the MSL altitude 
display reminds the pilot that altitude is GPS-derived. 

The Terrain Page has two selectable view settings: 

•  360˚ View—View from above aircraft depicting 

surrounding terrain on all sides 

•  120˚ View—View of terrain ahead of and 60˚ to 

either side of the aircraft flight path 

 

NOTE:  The Terrain Page gives a “Track Up” display 
orientation, as indicated by the “TRK” label shown on 
the display. This is the only orientation available on this 
page.
