The GDL 39 3D portable ADS-B receiver is a simple and economical solution for pilots who want to receive the benefits of ADS-B In. The GDL 39 3D combines a dual link ADS-B receiver that conveniently supplies ADS-B traffic and WAAS GPS data to Bluetooth compatible iOS and Android devices. The Garmin Pilot app enables both the display of backup attitude information and the optional moving map page with traffic overlay while in split screen mode, so it’s easy to view flight information alongside the attitude information at the same time. The GDL 39 3D’s ADS-B traffic is also compatible with the aera 795, aera 500 series, and GPSMAP 695.
Pilots can receive ADS-B traffic information and alerts to help identify potential traffic conflicts. The dual link GDL 39 3D offers a comprehensive view of traffic information and receives traffic on both ADS-B frequencies, 1090 ES and 978 UAT. ADS-B In technology enables the GDL 39 3D to receive Traffic Information Service-Broadcast (TIS-B) and helps pilots gain a better understanding of the traffic picture around them.
The GDL 39 3D includes advanced ADS-B features, including TargetTrend™ relative motion tracking and SURF technology. TargetTrend provides a faster, more intuitive way of judging target trajectories and closure rates in relation to your aircraft's position. In dense traffic environments, TargetTrend allows the pilot to more easily discern the aircraft that pose the greatest threat, which an save vital time and reduce workload. SURF technology also supports the display of ADS-B-equipped surface targets on the map screen so pilots are more aware of other aircraft and surface vehicles on the ramp.
The Garmin Pilot application for the iPad and iPhone features synthetic vision as an option for premium subscribers. 3D Vision incorporates GPS-derived airspeed, altitude, and vertical speed overlaid on rich 3D topographic landscape. 3D Vision is transformed when optionally paired with the GDL 39 3D, which superimposes back-up aircraft attitude information over the Garmin SVX display.
