Section 2: TERRAIN Operation

Power Up

During power-up of the 400/500 Series unit, the terrain/obstacle database versions are displayed along 

with a disclaimer (Figure 2-1).  At the same time, the TERRAIN system self-test begins.  A failure message 
is issued if the test fails (see page 41).

TERRAIN Page 

The TERRAIN Page is in the NAV group of pages (see the 400/500 Series Pilot’s Guide for detailed 

information regarding page groups and pages).  To display the TERRAIN Page, select the NAV group and 
turn the small right knob until the TERRAIN Page is displayed (Figure 2-2).  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 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.

1.  Select the TERRAIN Page and press MENU.
2.  Select ‘View 120˚?’.
3.  Press 

ENT.  To switch back to a 360˚ view, repeat step 1, select ‘View 360˚?, and press ENT.
