Displaying TAWS-A Data

TAWS-A uses yellow (caution) and red (warning) to depict terrain and
obstacle (with a height greater than 200 feet above ground level, AGL) alerts
relative to aircraft altitude. Colors are adjusted automatically as the aircraft
altitude changes. The colors and symbols in Figure 10-11 and Tables 10-7 and
11-12 are used to represent terrain, obstacles, and threat locations.
