Detailed Operation
Radar
is required by the transmitter within the radar head
assembly. Pressing the
STBY/ON
key while in Standby
mode turns on the radar in the Weather Mode. While
in the ON mode in both Map and Weather modes, the
green RDR annunciator is on solid indicating that the
radar is energized and transmitting.
Test Mode
Pressing the
TEST
key while in the Standby mode
places the radar in the Test mode. The radar then
sends a test pattern that is displayed on the GMX 200.
Weather Mode
In the weather (WX) mode, the antenna is trans-
mitting and painting reflected returns on the screen.
This mode is intended for painting airborne weather
and is the normal operating mode for the unit. Radar
returns are painted in the following colors:
•
Black
•
Green
•
Yellow
•
Red
•
Magenta
Black is the weakest return while Magenta shows
where the strongest returns were obtained. While in
the weather mode (GWX 68 only), the gain can be
adjusted with the
Gain -
and
Gain +
keys.
MAP Mode
The Map (MAP) mode is used for obtaining returns
from the ground. Map mode is available for the GWX
68, ART2000/2100, RS 811A, and RS 181A. In this
mode, the return data is rendered in the following
colors:
