Detailed Operation
ADS-B Traffic
Degraded Target
Degraded targets are shown with the “bullet”
symbol. A degraded target has limited positional
accuracy and can either be an uplinked TIS-B target,
or an ADS-B target who’s GPS position has degraded.
When a degraded target is selected via the
SELECT
key in the Traffic function, no distance to the target is
displayed, as it cannot be computed accurately.
Target Color
Service vehicle targets and aircraft targets report-
ing on the ground are colored in tan. Airborne aircraft
targets are usually cyan in color. However, the target
will be yellow if it is within 5 NM and 2,000 feet verti-
cally above or below your position. Selected targets are
green in color.
Surface Targets
Surface vehicle targets, in addition to ADS-B tar-
gets, are supported and are shown as tan, rectangular
icons. They are displayed both on the Traffic Function
page, and on the Custom Map when traffic is turned
on.
Traffic Altitude Values
Altitudes shown next to the traffic icon are in hun-
dreds of feet (09 = 900 feet). Altitude values shown in
all other locations and displays are the actual values in
feet (+100 = 100 feet).
Ident
The
Ident
smart key allows the pilot to initiate a
sequence that is equivalent to a standard transponder
“Ident,” as requested by ATC. When pressed, the Ident
flag will be displayed while the GDL 90 UAT broadcasts
the ident. The GMX 200 must be configured to be the
UAT’s control panel for this function to be available.
