10.3.5 Using TAWS
During unit power-up, the terrain/obstacle database versions are displayed.
At the same time, TAWS self-test begins. One of the following aural messages is
generated:
•“TAWS System Test OK” (not given if the aircraft is on the ground)
•“TAWS System Failure”
TAWS information can be displayed on the Map page.
Terrain and obstacles
with heights greater than 200 feet Above Ground Level (AGL) are displayed
in yellow and red. The GTN 6XX adjusts colors automatically as the aircraft
altitude changes.
