Terrain Alerting
Terrain alerting functions increase situational awareness and help reduce
controlled flight into terrain (CFIT). Visual and aural annunciations alert the
pilot when terrain and obstacles are within the given altitude threshold from
the aircraft.
10.5.1 Terrain Alerting Requirements
• A valid terrain/obstacle database
• A valid 3-D GPS position solution
10.5.2 Terrain Alerting Limitations
NOTE:
The data contained in the databases comes from government
agencies. Garmin accurately processes and cross-validates the data but
cannot guarantee its accuracy or completeness.
Terrain alerting uses terrain and obstacle information supplied by government
sources. Terrain information is based on terrain elevation information in a
database that may contain inaccuracies. Individual obstructions may be shown if
available in the database. The data undergoes verification by Garmin to confirm
accuracy of the content.
