TAWS Terrain Color Legend
Each color represents a terrain elevation in relation the aircraft’s current
altitude. Table 2-6 shows color samples at 500 ft steps. The system
provides a smooth color transition to changing terrain elevations and
aircraft altitudes.
Table 2-6 Terrain Color Scheme
The TAWS system has a predictive terrain alert “or quiet zone” around
each airport runway to help reduce nuisance alerts during a normal
takeoff or landing procedures. GPWS-type alerts such as ‘excessive
descent rate’, however, are still active and will alert in this area.
Note that the predictive alert suppression is related to the location of
the alert, not the position of the aircraft. Aircraft within a quiet zone
may still predict alerts on terrain or obstacles outside the quiet zone.
See the ‘forward looking terrain avoidance (FLTA)’ section for more
information on quiet zones.
