Color Interpretation
The Garmin TERRAIN system uses black, yellow,
and red to depict terrain information relative to aircraft
altitude.
General Database Information
The Garmin TERRAIN system uses terrain and
obstacle information supplied by government sources.
The data undergoes verification by Garmin to confirm
accuracy of the content, per TSO-C151b.
However, the
information displayed should never be understood to
be all-inclusive. Pilots must familiarize themselves
with the appropriate charts for safe flight.
NOTE:
The data contained in the terrain and
obstacle databases comes from government
agencies. Garmin accurately processes and cross-
validates the data, but cannot guarantee the
accuracy and completeness of the data.
The terrain/obstacle databases are contained on a
datacard which is inserted in the right-most slot of the
400W Series units.
Database Versions
The version and area of coverage of each ter-
rain/obstacle database is shown on the Terrain Data-
base Versions Page, located in the AUX Page Group.
Databases are checked for integrity at power-up. If a
database is found to be missing and/or deficient, the
TERRAIN system fails the self-test and issues a failure
message.
TERRAIN Database Information
Database Updates
Terrain/obstacle databases are updated periodi-
cally with the latest terrain and obstacle data. Visit the
Garmin website to check for newer versions of terrain/
obstacle databases. Compare database cycle numbers
to determine if a newer version is available.
The database update process includes either
reprogramming or replacing the database card and
inserting the updated card in the right card slot on the
unit front panel. The terrain/obstacle database may
be downloaded via the intenet and the card repro-
grammed using a USB programmer available from
Garmin. Contact Garmin at 800-800-1020 or at www.
garmin.com for more information.
