Synthetic Vision is intended as an aid tosituational awareness only and may not provide either the accuracy orreliability upon which to solely base decisions and/or plan maneuvers to avoidterrain, obstacles, or traffic.Synthetic Vision is a visual enhancement to the G3X. Synthetic Vision depicts aforward-looking attitude display of the topography immediately in front of the aircraft.Synthetic Vision information is shown on the Primary Flight Display (PFD). The depictedimagery is derived from the aircraft attitude, heading, GPS three-dimensional position,and databases of terrain, obstacles, and other relevant features. Loss of any of therequired data, including temporary loss of the GPS signal, will cause Synthetic Visionto be disabled until the required data is restored.The Synthetic Vision terrain display shows land contours (colors are consistentwith those of the topographical map display), large water features, towers, and otherobstacles over 200’ AGL that are included in the obstacle database. 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 Synthetic Vision to provide visual and auditory alerts toindicate the presence of terrain and obstacle threats relevant to the projected flightpath. Terrain alerts are displayed in red and yellow shading on the PFD.The terrain display is intended for situational awareness only. It may not provide theaccuracy or fidelity on which to base decisions and plan maneuvers to avoid terrainor obstacles. Navigation must not be predicated solely upon the use of the terrain orobstacle data displayed by Synthetic Vision.
