The GDL 39 offers the complete package that combines a dual-link ADS-B receiver and Garmin’s industry-leading GPS receiver into a single unit that streams ADS-B datalink traffic and subscription-free weather to select Garmin aviation portables including the aera® 796/795, aera 500 series, GPSMAP® 696/695, G3X™ experimental flight display and select Garmin Pilot™ app compatible devices.

Subscription-free weather information is continuously broadcast using the FAA’s 978 MHz UAT uplink and is similar to the basic services offered by leading commercial satellite weather providers. Weather services include access to NEXRAD imagery (which can also be put in motion as new data is collected on select devises), METARs, TAFs, winds and temperatures aloft, PIREPs, NOTAMs and more.

Pilots can also receive ADS-B datalink traffic information with alerts to help identify potential traffic conflicts. In addition to receiving traffic data from ADS-B ground stations, the dual-link GDL 39 features direct air-to-air ADS-B reception on both ADS-B frequencies (1090 and 978 UAT) to provide a more comprehensive view of potential flight path conflicts. In order to maximize available traffic information for the display, the aircraft should also be equipped with a compliant ADS-B “out” solution like the GDL 88 or GTX 330ES/33/23 ES transponders.

The GDL 39 provides weather and traffic information via wireless support for compatible mobile devices like the iPad and Andriod tablets via built-in Bluetooth® connection and wired connections for compatible Garmin portables.  Coming later this year, Bluetooth support will be added to the aera 795/796 via a free software download. The Bluetooth connection also allows two devices to connect to GDL 39 at once wirelessly, making it possible for
two-pilot crews to view traffic and weather on separate devices from the same GDL 39. Garmin products including the aera 795/796, 500/510/550/560, GPSMAP® 695/696 and G3X series can connect to the GDL 39, as well as an external power source, via a wired connection. Traffic only compatible displays include the
GPSMAP 496/495 and GPSMAP 396.

The portable design of the GDL 39 also includes a built-in WAAS GPS receiver, which brings Garmin’s industry-leading GPS location information to wirelessly connected mobile devices. The GDL 39 integrates seamlessly with the Garmin Pilot app to support its navigation functions with reliable and accurate GPS capability.
