differing from the baro-corrected altitude.
DISPLAYING TAWS-b DATA
TAWS-B uses yellow (caution) and red (warning) to depict terrain and obstacles (with heights 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 6-89 and Table 6-11 are used to represent terrain,
obstacles, and potential impact points.
