TERRAIN Interface*

• Note •

*TERRAIN functionality is a standard feature found in GNC

420 units with main software version 5.01 or above and valid

terrain and obstacle databases installed.

Garmin TERRAIN is a terrain awareness system incorporated into

GNC 420 units to increase situational awareness and aid in reducing

controlled flight into terrain. The TERRAIN function displays altitudes

of terrain and obstructions relative to the aircraft’s altitude and are

advisory in nature only. Individual obstructions may be shown if

available in the database, however, not all obstructions may be

available in the database and data may be inaccurate. TERRAIN

information should be used as an aid to visual acquisition and not use

to navigate or maneuver to avoid terrain.

For for a more detailed description of the TERRAIN function, refer to

the Garmin GNC 420 Pilot's Guide and Reference, P/N 190-00140-20,

Revision H dated May 2006 or later revision.
