APPENDIX B
The terrain database contains the terrain mapping data. The airport terrain database contains increased
resolution terrain data around airports. These databases are updated periodically and have no expiration date.
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.
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 AOPA Airport Directory provides data on airports and heliports throughout the U.S., and offers detailed
information for over 5,300 U. S. airports, along with the names and phone numbers of thousands of FBOs. This
database is updated four times per year.
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.
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 will no longer function.
AUTOMATIC DATABASE SYNCHRONIZATION FEATURE
The automatic database synchronization feature automatically transfers the database from a single SD
database card to the SD cards on each PFD and the MFD to ensure that all databases are synchronized
throughout the system. After power-up, the system compares all copies of each applicable database. If similar
databases do not match, the most recent valid database is automatically copied to each card in the system that
does not already contain that database.
The following databases are checked and synchronized: Basemap, Safetaxi, Airport Terrain, Obstacle,
Airport Directory, and Terrain. This feature applies only to databases that are stored on the SD card that
resides in the bottom slot of each display. This feature does not apply to the active navigation database which
is stored internally in each display, or to the charts databases (FliteCharts and ChartView) which are only
required to be present on the MFD. The typical procedure would be to download new databases to the MFD
card, then synchronize the data to the PFD(s).
NOTE: The 9-arc second terrain database may take as long as 100 minutes to synchronize using this method.
Therefore the user may want to transfer the data using a PC, or connect the system to a ground power
source while performing the database synchronization.
The synchronization progress may be monitored on the AUX-System Status Page in the Sync Status section
of the Database Window (Figure B-8). This section shows the synchronization status of each applicable
database, including the percent complete, time remaining, and to which displays the databases are being
copied. When the synchronization is complete, the status is listed as ‘Complete’, followed by the displays to
which the databases were copied. This sub-section is only present when a sync is occurring or has occurred
on the current power-up.
An indication of ‘Complete’ still requires a power cycle before the synchronized databases will be used by
the system.
