Terrain alerting on the synthetic vision display corresponds to the red and yellow symbols on the Widget Map, HSI Map, and Navigation Map. For more detailed information regarding Synthetic Vision Terrain and Obstacle Data, refer to the Terrain Avoidance and Warning System (TAWS) section in Hazard Avoidance.

Obstacles are represented on the synthetic vision display by standard two dimensional tower symbols found on the Widget Map and Navigation Map. Obstacle symbols appear in the perspective view with relative height above terrain and distance from the aircraft. Unlike the Widget Map and Navigation Map display, obstacles on the synthetic vision display do not change colors to warn of potential conflict with the aircraft’s flight path until the obstacle is associated with an actual terrain alert. Obstacles greater than 1000 feet below the aircraft altitude are not shown. Obstacles are shown behind the airspeed and altitude displays.
