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 will no longer be active.
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.
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.
TERRAIN
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 terrain database is updated periodically and has no expiration date.
