Terrain Page - Garmin GPS 500 Pilot's Manual & Reference

2.5 TERRAIN PAGE

NOTE: GPS 500 units may* display either a
TERRAIN Page or a TAWS Page, (but not both)
depending upon the installed hardware and
configuration.
* Some earlier units are not equipped to support the
TERRAIN and/or TAWS functionality, so therefore will not
have a TERRAIN or TAWS page available.
TERRAIN Page
To display the TERRAIN Page, select the NAV Page
Group and turn the small right knob until the TERRAIN
Page is displayed (Figure 2-27). The TERRAIN Page
displays:
• GPS-derived MSL altitude in increments of 20
feet or 10 meters, depending on unit configura-
tion. The 'G' to right of the MSL altitude display
reminds the pilot that altitude is GPS-derived.
• Aircraft ground track
• Terrain Range - Indicates the terrain elevation in
colors relative to the aircraft altitude
• Range marking rings - (1 nm, 2 nm, 5 nm, 10 nm,
25 nm, 50 nm, and 100 nm)
• Heading Indicator - The heading indication on the
TERRAIN Page always displays 'TRK' for Track-
up, unless there is no valid heading
• Obstacles
• Potential Impact Points
NOTE: See Section 10 for a full description of
TERRAIN functions.
