The depicted imagery is derived fromthe aircraft's three-dimensional position, and databases of terrain, obstacles, and otherrelevant features. Loss of the GPS signal, will cause 3D Vision to be disabled until itis restored.The 3D Vision terrain display shows land contours (colors are consistent with thoseof the topographical map display), large water features, towers, and other obstaclesover 200’ AGL that are included in the obstacle database (if present). Cultural featureson the ground such as roads, highways, railroad tracks, cities, and state boundariesare not displayed even if those features are found on the Navigation Map. The terraindisplay 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 indicatethe 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 andplan maneuvers to avoid terrain or obstacles. Navigation should not be predicatedupon the use of the terrain or obstacle data displayed by 3D Vision.Touch and drag the three-dimensional view to change the perspective.
