ADDITIONAL FEATURES
8.1 SYNTHETIC VISION SYSTEM (SVS)
WARNING:
Use appropriate primary systems for navigation, and for terrain, obstacle, and traffic avoidance.
SVS is intended as an aid to situational awareness only and may not provide either the accuracy or reliability
upon which to solely base decisions and/or plan maneuvers to avoid terrain, obstacles, or traffic.
The Synthetic Vision System (SVS) is a visual enhancement to the G1000H Integrated Flight Deck. SVS depicts
a forward-looking attitude display of the topography immediately in front of the aircraft. The field of view is 30
degrees to the left and 35 degrees to the right. SVS information is shown on the Primary Flight Display (PFD), or
on the Multifunction Display (MFD) in Reversionary Mode (Figure 8-120). The depicted imagery is derived from
the aircraft attitude, heading, GPS three-dimensional position, and a six arc-second database of terrain, obstacles,
and other relevant features. The terrain data resolution of six arc-seconds, meaning that the terrain elevation
contours are stored in squares measuring six arc-seconds on each side, is required for the operation of SVS. Loss
of any of the required data, including temporary loss of the GPS signal, will cause SVS to be disabled until the
required data is restored.
The SVS terrain display shows land contours, large water features, towers, and other obstacles over 200’ AGL
that are included in the obstacle database. 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 MFD map. The
terrain display also includes a north–south east–west grid with lines oriented with true north and spaced at one
arc-minute intervals to assist in orientation relative to the terrain. The colors used to display the terrain elevation
contours are similar to that of the topo map display.
The Helicopter Terrain Awareness and Warning System (HTAWS) is integrated within SVS 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 on the PFD.
The terrain display is intended for situational awareness only. It may not provide the accuracy or fidelity on
which to base decisions and plan maneuvers to avoid terrain or obstacles. Navigation must not be predicated
solely upon the use of the HTAWS terrain or obstacle data displayed by the SVS.
The following SVS enhancements appear on the PFD:
• Pathways
• Flight Path Marker
• Horizon Heading Marks
• Traffic Display
• Airport Signs
• Runway Display
• Terrain Alerting
• Obstacle Alerting
