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. Detailed Operation ADS-B Traffic 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. Target Color ADS-B Broadcast ID Info Service vehicle targets and aircraft targets reporting 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 vertically above or below your position. Selected targets are green in color. Surface Targets Operation The controls at the bottom of the screen allow you to zoom in and out, initiate an Ident when connected to a GDL 90 UAT, and to select each traffic target on the screen. 1. Press the FN key to reach the Function page showing the TRAF (Traffic) "smart" key. Surface vehicle targets, in addition to ADS-B targets, 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. 2. Press TRAF. 3. Press the In key to zoom in. Press the Out key to zoom out. 4. With the GDL 90 UAT only, press the Ident key to initiate an Ident for ATC purposes. A green flag will appear on the left side of the display when the GDL 90 UAT reports that it is sending an ident over the air. Traffic Altitude Values Altitudes shown next to the traffic icon are in hundreds of feet (09 = 900 feet). Altitude values shown in all other locations and displays are the actual values in feet (+100 = 100 feet). 5. Press the Select key to consecutively select each Traffic item that is shown on the display. When a target is selected, additional information about that target is shown in the upper right corner of the display. The selected target will be highlighted in green on the display. Surface vehicle targets cannot be selected. Information about the selected target includes: 190-00607-02 Rev C 41

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.
ADS-B Broadcast ID Info
