6.4 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 if the aircraft is outside of the terrain database coverage area.
NOTE: Terrain-SVS is included with the Synthetic Vision System (SVS). If equipped with TAWS-B, the TAWS-B
option will take precedence over Terrain-SVS.
