INDEX
Baro-corrected altitude (or indicated altitude) is derived by adjusting the altimeter setting for local atmospheric
conditions. The most accurate baro-corrected altitude can be achieved by frequently updating the altimeter setting
to the nearest reporting station along the flight path. However, because actual atmosphere conditions 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 GPS-MSL altitude. This variation results in the aircraft’s true altitude differing from
the baro-corrected altitude.
DISPLAYING TAWS DATA
TAWS uses yellow (caution) and red (warning) to depict terrain and obstacles with heights greater than 200
feet above ground level, AGL. Alerts are given relative to aircraft altitude. Colors are adjusted automatically as
the aircraft altitude changes. The colors and symbols shown in the figure and table below are used to represent
terrain, obstacles, and potential impact points.

WARNING: Red obstacle is above or within
100’ below current aircraft altitude
CAUTION: Yellow obstacle is between 100’
and 1000’ below current aircraft altitude
