13.2 TAWS PAGE
See Section 3.6 for a complete description of the TAWS
Page and its operation.
TAWS Symbols
The symbols and colors in Figure 13-1 and
Table 13-1 are used to represent obstacles and
potential impact points on the TAWS Page. TAWS
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.
