TERRAIN Interface

TERRAIN functionality is a standard feature found in GNS
430W 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
GNS 430W 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 400W-Series GPS Navigator Pilot's Guide and Reference,
P/N 190-00356-00, Revision A or later revision.
