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.
• Obstacle – The obstacles 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. The rotorcraft database
includes all reported obstacles regardless of height. 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.
Several obstacle database options are available. Obstacle databases created
for GTN software version 5.10 or later include all power lines or only HOT
lines depending on the type of obstacle database installed. Hazardous
Obstacle Transmission (HOT) Lines are those power lines that are co-located
with other FAA-identified obstacles. The installed obstacle database type
can be verified on the System Status page. Power line data is available for
the contiguous United States as well as small parts of Canada and Mexico.
• 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.
