Vertical Situation Display (VSD) - Terrain Background
1 Terrain Profile Line
Represents the highest terrain within the enroute swath.
• highest points of the terrain below and ahead of the airplane
• terrain is depicted so the true altitude separation between the airplane
and terrain is shown
• terrain behind the airplane is drawn equal to the terrain at the current
position
• VSD terrain uses the same color coding that is used to depict EGPWS
terrain on the lateral map –
• green: terrain is more than 500 feet (250 feet gear down) below the
airplane
• amber: terrain ranges from 500 feet below (250 feet gear down) to 2000
feet above the airplane
• red: terrain is 2000 feet above the airplane.
