Vision - Garmin AERA 660 Pilot's Manual

2.2 3D VISION
3D Vision provides a three-dimensional view of terrain features as seen from outside
the aircraft. 3D Vision imagery shows the relevant features in relation to the aircraft.
WARNING: Use appropriate systems for navigation, and for terrain, obstacle,
and traffic avoidance. 3D Vision does not provide either the accuracy or
reliability upon which to base decisions and/or plan maneuvers to avoid
terrain, obstacles, or traffic.
3D Vision is a visual enhancement to the aera 660. 3D Vision depicts the topography
as seen from outside the aircraft. The depicted imagery is derived from the aircraft's
three-dimensional position, and databases of terrain, obstacles, and other relevant
features. Loss of the GPS signal, will cause 3D Vision to be disabled until it is restored.
The 3D Vision terrain display shows land contours (colors are consistent with those
of the topographical map display), large water features, towers, and other obstacles
over 200' AGL that are included in the obstacle database (if present). Cultural features
on the ground such as roads, highways, railroad tracks, cities, and state boundaries
are not displayed even if those features are found on the Navigation Map. The terrain
display also includes a north-south east-west grid with lines oriented with true north.
Terrain is integrated within 3D Vision to provide visual and auditory alerts to indicate
the presence of terrain and obstacle threats relevant to the projected flight path.
Terrain alerts are displayed in red and yellow shading.
3D Vision does not provide the accuracy or fidelity on which to base decisions and
plan maneuvers to avoid terrain or obstacles. Navigation should not be predicated
upon the use of the terrain or obstacle data displayed by 3D Vision.
Touch and drag the three-dimensional view to change the perspective.
