HAZARD AVOIDANCE
pressure, temperature, and lapse rates have fixed values), it is common for the baro-corrected altitude (as read
from the altimeter) to differ from the GSL altitude. This variation results in the aircraft’s GSL altitude differing
from the baro-corrected altitude.
DISPLAYING HTAWS DATA
HTAWS uses yellow (caution) and red (warning) to depict terrain and obstacle alerts relative to aircraft
altitude. Colors are adjusted automatically as the aircraft altitude changes. The colors and symbols in Figure
6-74 and Tables 6-7 and 6-8 are used to represent terrain, obstacles, and potential impact points.
