11.2 TERRAIN PAGE

See Section 3.5 for a complete description of the
TERRAIN Page and its operation.
TERRAIN Symbols
The symbols and colors in Figure 11-1 and Table
11-1 are used to represent obstacles and potential
impact points on the TERRAIN Page. TERRAIN
uses yellow (caution) and red (warning) to depict
terrain information relative to aircraft altitude.
Each color is associated with an alert severity level.
Terrain graphics and visual annunciations also use
these color assignments.
