HAZARD AVOIDANCE
6.6 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 installed terrain database coverage
area.
NOTE: Terrain-SVS is standard when the Synthetic Vision System (SVS) option is installed. The TAWS-B
option will take precedence over Terrain-SVS when TAWS-B is also installed.

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

Note that all obstructions may not be available in the terrain and obstacle database. No terrain and obstacle
