The GDL 39 has the ability to receive two types of traffic; air-to-air and ground-to-air. The GDL 39 can detect and display other aircraft in the vicinity of your aircraft, that are equipped with an ADS-B Out transponder with ES (Extended Squitter) or a Universal Access Transceiver (UAT). The GDL 39 also has the ability to receive Traffic Information Service (TIS-B) from FAA ground stations transmitted over the 1090 MHz datalink. TIS-B traffic includes targets being tracked through ADS-B technology and paints a comprehensive picture of traffic within +/- 15NM and +/- 3,500 feet of your position. This traffic service will only be available to aircraft that are equipped with an approved ADS-B Out solution and a certified WAAS GPS position source.

The process for updating the firmware will vary depending on what device you are using with the GDL 39. If you are using the GDL 39 along with a Garmin aviation portable device the software will be received through the portable device. The software for your portable can be obtained by either visiting myGarmin.com or using our WebUpdater program. If you are using the GDL 39 along with an iOS or Android moible device you can use the GDL 39 Utility Application available on the iTunes App Store and the Google Play Store. This is a free download and requires a Bluetooth connection between the GDL 39 and the mobile device. In either case, the unit will only update when connected to an external power source.

The GDL 39 can be connected to as many as three devices at one time. A connection to the GDL 39 can be made two different ways; either by using a power/data cable or a Bluetooth connection. The GDL 39 can be connected to several Garmin aviation portables via a power/data cable (included with the GDL 39) as well as two bluetooth enabled devices (i.e. aera 796, iPad, or Android tablet). Compatible Garmin Aviation products include the aera 795/796, aera 5XX Series, GPSMAP 695/696, GPSMAP 495/496, GPSMAP 396, G3X Garmin Pilot Application for iOS and Android tablets and phones.

The GDL 39 has the ability to receive subscription free Flight Information Service (FIS-B) that is broadcast from FAA ground stations around the United States and the Gulf of Mexico. FIS-B weather products include NEXRAD in the Continental U.S., NEXRAD Regional, TFR, TAF, PIREP, NOTAM, SIGMET/AIRMET, METAR, and Winds Aloft information. One key difference between FIS-B and satellite based weather services is that FIS-B is broadcast from the ground upward. Therefore your proximity to the ground station may present some line-of-sight disturbances and services may not be received until airborne.

No, the GDL 39 will only interface with Garmin Aviation portables and experimental products, as well as iOS and Android tablets and phones. These products include the aera 796/795, GPSMAP 696/695, aera 5XX Series, GPSMAP 496/495, GPSMAP 396, and the G3X.

The GDL 39 Remote unit requires two antennas. One for GPS/WAAS and one to receive the ADS-B frequency. The GA 35 and AV-74 antennas would be good choices.

The orientation of the aircrafts heading is determined by the GPS which the GDL 39 is plugged into. The GDL 39 does not have internal AHRS data.

The GDL 39R is designed for the G3X system, which already has synthetic vision. We have not heard of any plans to release a 3D version.

The GDL 39 Remote unit requires two antennas. One for GPS/WAAS and one to receive the ADS-B frequency. The GA 35 and AV-74 antennas would be good choices. The GA 25 is not compatible.

No, it cannot.

No, the GDL 39R is not an approved WAAS GPS Source.

The G5 uses WAAS GPS for it's signal, so there would be no need to connect to the GDL39.

Yes, the vertical antenna that attaches to the unit is included. You cannot split GA35 signal to the unit.
