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 optional Synthetic Vision System (SVS) is a visual enhancement to the G1000 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 8-91). The depicted imagery is
derived from the aircraft attitude, heading, GPS three-dimensional position, and a nine arc-second database of
terrain, obstacles, and other relevant features.  The terrain data resolution of nine arc-seconds, meaning that 
the terrain elevation contours are stored in squares measuring nine 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 (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. 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  optional  Terrain  Awareness  and  Warning  System  (TAWS)  or  standard  Terrain-SVS  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 Terrain–SVS or TAWS 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
