B.7.2 Other G1000 Databases
The following G1000 databases are stored on Supplemental Data Cards provided by Garmin.
Terrain, Airport Terrain, and Obstacle
G1000 topography, terrain, airport terrain, and obstacle data is stored on a Supplemental Data Card provided by
Garmin. The obstacle database update cycle is every 56 days. The terrain and airport terrain database is updated
less often, and on an irregular basis. Since these databases are not stored internally in the MFD or PFD,
Supplemental Data Cards containing identical database versions must be kept in both displays to retain terrain and
obstacle data. A Supplemental Data Card should be inserted into the bottom card slot of the PFD and MFD.
Expanded Basemap
The expanded basemap database contains data for the topography and land features, such as rivers, lakes, and
towns. It is updates only periodically, with no set schedule. There is no expiration date. This database is not
stored internally in the MFD or PFD. Supplemental Data Cards containing identical database versions must be
kept in both displays. A Supplemental Data Card should be inserted into the bottom card slot of the PFD and
MFD.
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. This database is not stored internally in the MFD or PFD. Supplemental Data Cards
containing identical database versions must be kept in both displays. A Supplemental Data Card should be
inserted into the bottom card slot of the PFD and MFD.
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. The SafeTaxi database
should be copied to the Garmin supplied Supplemental Data Card which will reside in the bottom card slot of the
MFD.
FliteCharts
The FliteCharts database contains terminal 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 be active. The
FliteCharts database should be copied to the Garmin supplied Supplemental Data Card which will reside in the
bottom card slot of the MFD.
