Garmin Databases

WARNING: 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 following GDU 620 databases are stored on Supplemental Data Cards
provided by Garmin:
• Terrain – The terrain database contains terrain mapping data. It is updated
periodically and has no expiration date.
• Airport terrain – The airport terrain database contains detailed airport
terrain data. It is updated periodically and has no expiration date. This
database is not required when a 9 arc-second terrain database is in use.
• Obstacle – The obstacle database contains data for obstacles, such as towers,
that pose a potential hazard to aircraft. Obstacles 200 feet 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. This database is updated on a 56-day cycle. Obstacles
will still be shown after the database has expired.
• SafeTaxi – The SafeTaxi database contains detailed airport diagrams for
selected airports. These diagrams aid in following ground control instructions
by accurately displaying the aircraft position on the map in relation to
taxiways, ramps, runways, terminals, and services. This database is updated
on a 56-day cycle. SafeTaxi will still be shown after it has expired.
• FliteCharts – The FliteCharts database contains procedure charts for the
United States only. This database is updated on a 28-day cycle. If not updated
within 180 days of the expiration date, FliteCharts no longer functions.
• Airport Directory (optional) – The airport directory database contains
airport facility and FBO information. This database is optional and "N/A"
will be displayed in white text on the startup screen if the database is not
installed. This database may be available in multiple versions with varying
update cycles and/or content.
Since these databases are not stored internally in the GDU 620, a Supplemental
Data Card containing identical database versions must be kept in each display
unit for dual installations. After subscribing to the desired database product,
