Displaying Taws-B Data - Garmin G1000 Manual

seldom match the standard conditions defined by the International Standard Atmosphere (ISA) model (where
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 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 the figure and tables below are used to represent terrain,
obstacles, and potential impact points.
