NOTE: The data contained in the terrain and obstacle databases comes from
government and private agencies. Garmin accurately processes and cross-
validates the data, but cannot guarantee the accuracy and completeness
of the data.
The following 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. Approximately one minute is
required to verify the rotorcraft terrain database on start up.
• Obstacles – The obstructions 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.
