GDL 88 ADS-B Reporting

The GDL 88 is a remote-mount ADS-B transceiver that sends ADS-B out
messages to ATC and other aircraft and communicates ADS-B In data to panel-
mounted avionics for the display of traffic and weather. Reference the GDL 88
Pilot Guide for a full description of GDL 88 functions. When a GTN is interfaced
to a GDL88 transceiver for ADS-B Out functions the GTN can control some
aspects of the ADS-B Out message and the GTN may provide position information
to the GDL88. The display and control of the information sent depends on the
equipment installed and how it is configured by the installer. Some installations
allow control by the pilot of the information sent, while others do not.
The Anonymous Mode, when armed, will replace the identifying information
in the ADS-B Out message with a temporary randomized number for privacy
while the position information will still be provided. The call sign will be sent as
"VFR." To enable Anonymous Mode, the Squawk Code must be set to the VFR
code (based on the GDL 88 configuration) and the Anonymous key must be
selected.
