HAZARD AVOIDANCE

VERTICAL SITUATION DISPLAY (VSD) TERRAIN

The system offers a Vertical Situation Display (VSD), which includes a profile of terrain and obstacles in an
inset window on the bottom of the Navigation Map Page. Although the VSD does not display Terrain-SVT or
TAWS-B alerts and potential impact areas, the VSD does use many of the same colors and symbols as these
systems to depict relative terrain and obstacles within the VSD.
Enabling/Disabling the Vertical Situation Display (VSD):
1) Select the 'Map - Navigation Map' Page.
2) Press the Map Opt Softkey.
3) Press the Inset Softkey.
4) Press the VSD Softkey to enable or disable the VSD.
Or :
1) Select the 'Map - Navigation Map' Page.
2) Press the MENU Key.
3) Select 'Show VSD' or 'Hide VSD' (choice dependent on current state) and press the ENT Key.
The same controls which enable/disable the display of relative terrain and obstacles on the 'Map - Navigation
Map' Page also control the display of this information in the VSD.
VSD DISPLAY
When the VSD is enabled, terrain and obstacles in the VSD will be shown if the aircraft altitude is low
enough or the VSD altitude range is high enough for the terrain to be in view (absolute terrain will be shown
in gray if the TER Softkey is selected off on the 'Map - Navigation Map' Page.
The depicted terrain profile represents an approximate forward-looking contour of the terrain based upon
the highest reported terrain elevations, measured at intervals defined by the terrain database resolution,
within a predefined width along the aircraft track between the aircraft present position and the end of the
map range. The predefined width is determined by the flight phase, as annunciated on the HSI, and is widest
during enroute or oceanic phases.
