o At ranges of 200 nm and less, areas not covered by
the terrain database are displayed using a 50 % red
dithered pattern.
o The Relative Terrain Map is rotated and scaled
consistent with the current map location, orientation
and range.
o When terrain data is scaled for display, the highest
elevation is used for each location to determine its
color.
o The 0.5 nm radius circles around obstacles are
displayed only if their radii after scaling are large
enough to be shown.
o If altitude information is not available then a warning
message is displayed on the map image with the text
“No Altitude Available. Relative Terrain Not Displayed.”
