12.4 DATABASE INFORMATION FOR TERRAIN

General Database Information

Garmin TERRAIN 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 displayed
information should never be understood as being all-
inclusive. Pilots must familiarize themselves with
the appropriate sectional 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
GNS 530 units (Appendix A).
NOTE: Obstacles 200’ and higher are included
in the Obstacle Database. It is very important
to note that not all obstacles are necessarily
charted and therefore may not be contained in
the Obstacle Database.

Database Versions

The version and area of coverage of each terrain/obstacle
database is shown on the Terrain Database Versions Page,
located in the AUX Page Group (Figures 12-10 and 12-11,
also Section 10.3). 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
displays the TERRAIN system failure message (see Table
12-3).
