6.8 TERRAIN-SVS
WARNING: Do not use Terrain-SVS information for primary terrain avoidance. Terrain-SVS is intended only
to enhance situational awareness.
NOTE: Terrain data is not displayed when the aircraft is outside of the terrain database coverage area.
NOTE: Terrain-SVS is included with the SVS option. Terrain-SVS will take precedence over Terrain Proximity.
G1000 Terrain-SVS is a terrain awareness system available with the Synthetic Vision System (SVS).  SVS

Terrain-SVSrequiresthefollowingcomponentstooperateproperly:
•Valid3-DGPSposition
•Validterrain/obstacledatabase
Terrain-SVS displays altitudes of terrain and obstructions relative to the aircraftposition and altitude with
referencetoadatabasethatmaycontaininaccuracies.Terrainandobstructionsareshownonlyiftheyareinthe

be used to navigate or maneuver around terrain.
Note that all obstructions may not be available in the terrain and obstacle database. No terrain and obstacle
informationisshownwithoutavalid3-DGPSposition.
