Garmin GDL® 39 — GDL 39 w/ GPSMAP39x/49x cable - 010-11689-02

Garmin GDL® 39 — GDL 39 w/ GPSMAP39x/49x cable is an ADS-B receiver that brings TIS-B traffic and subscription-free FIS-B weather to supported Garmin aviation portables and mobile devices. It is a practical choice for pilots who want portable access to airborne traffic and weather information, with WAAS GPS data available when used with Garmin Pilot on a mobile device.

Traffic Awareness

Receive TIS-B traffic on supported displays to add nearby traffic information to the cockpit. Supported Garmin Pilot, G3X Touch, G3X, aera, GPSMAP, ForeFlight Mobile, and FltPlan Go configurations provide varying target-display capabilities.

Subscription-Free Weather

View FIS-B weather on supported Garmin aviation portables and compatible mobile apps. This delivers ADS-B weather information without a weather subscription.

Flexible Device Connection

Connect by Bluetooth with compatible mobile devices and selected Garmin displays, or by cable where supported. This GDL 39 configuration is designated for use with a GPSMAP39x/49x cable.

Garmin Portable And Mobile Use

The GDL 39 supports Bluetooth connectivity with Garmin Pilot, ForeFlight Mobile, and FltPlan Go. With Garmin Pilot on a mobile device, it can also provide highly accurate WAAS GPS data. Garmin Pilot for Android™ devices does not support SVX™.

Display-Specific Capabilities

Supported Garmin displays include G3X Touch, G3X, aera 795/796, aera 660, aera 500 series, GPSMAP 695/696, GPSMAP 495/496, and GPSMAP 396. Traffic, weather, connection method, and attitude-data support differ by the connected display or app; GPSMAP 495/496 and GPSMAP 396 display 8 traffic targets using TIS-A Symbol Format, while several other supported configurations display up to 30.

Portable Receiver Details

The GDL 39 operates from 10 to 32 VDC and draws 3.5 W maximum, with total power while charging rated at 8.0 W maximum. Its rechargeable lithium-ion battery supports portable operation, while the specified operating altitude reaches 55,000 ft and nominal operating velocity range is 0 – 800 kts (411 m/s).

The Garmin GDL® 39 w/ GPSMAP39x/49x cable is an ADS-B receiver package that provides TIS-B traffic and subscription-free FIS-B weather on compatible Garmin aviation portables and mobile devices. When used with Garmin Pilot on a mobile device, the GDL 39 can also provide highly accurate WAAS GPS data. Compatible-device capabilities, including connection method and attitude display support, vary by display and app.

Access Weather, Traffic and GPS Information

  • Receives subscription-free weather
  • Advanced ADS-B "dual-link" traffic with TargetTrend™ and TerminalTraffic™ technology
  • Wireless Bluetooth® connectivity with the Garmin Pilot, ForeFlight Mobile and FltPlan Go apps, aera 660 or 796/795
  • Built-in WAAS GPS receiver
  • Designed to sit on aircraft glareshield

Access Automatic Dependent Surveillance - Broadcast (ADS-B) traffic and subscription-free weather on your aviation portable or mobile device with the GDL 39 ADS-B receiver. When using Garmin Pilot, the GDL 39 can provide highly accurate WAAS GPS data.

Comprehensive Aviation Weather

GDL 39 features ADS-B “In” datalink technology that allows it to receive subscription-free Flight Information Service-Broadcast (FIS-B) weather information over the FAA’s 978 MHz Universal Access Transceiver (UAT) uplink. Easily access animated NEXRAD radar, METARs, TAFs, winds and temperatures aloft, PIREPs, NOTAMs and more right on your compatible Garmin aviation portable or through the Garmin Pilot app on your iPad® or Android™ device.¹

Spot Potential Traffic Threats

GDL 39 can receive ADS-B position reports directly from other aircraft in your vicinity. Because the FAA permits ADS-B broadcasts on 2 frequencies (978 UAT and 1090 ES), GDL 39 contains both receivers so you can see a comprehensive view of all ADS-B “Out” equipped targets. The compatible display² will alert you by announcing traffic targets both audibly and visually. Spoken audio alerts announce “Traffic, Traffic” to get you looking right away.

ADS-B “In” technology also allows the GDL 39 to receive Traffic Information Service-Broadcast (TIS-B) information. TIS-B allows you to view the same dynamic traffic picture that ATC ground controllers are seeing when you're either participating with an ADS-B “Out” solution or within a certain range of another ADS-B “Out” participating aircraft when within a service area.³ Our correlation technology automatically displays the highest-integrity traffic data from multiple sources, preventing ghost or duplicate targets.

Advanced Display Capabilities

With Garmin Pilot on your mobile device, you can receive advanced traffic display features like TargetTrend™ relative motion tracking that provides a faster, more intuitive way of judging target trajectories and closure rates in relation to your aircraft's position. TargetTrend relies on ADS-B “Out” equipped targets, so while not all targets will display with trajectories today, this feature will be come increasingly beneficial to pilots in the future. TerminalTraffic provides pilots with the most comprehensive picture of ADS-B-equipped aircraft and ground vehicles in the airport environment. ADS-B-equipped aircraft in-flight are easily distinguished from ground vehicles and taxiing aircraft, which are displayed using distinct colors and symbols.

More Accurate GPS

GDL 39 can provide highly accurate WAAS GPS location information to your mobile device — such as an iPad® — using Bluetooth technology. This provides your device with the precision you’d expect from our aviation-grade navigation devices, updating at a rate of up to 5 times per second depending on the capability of the device used.

Go Wireless

With built-in Bluetooth® capability, GDL 39 can wirelessly send the data it collects to devices running the Garmin Pilot, ForeFlight Mobile and FltPlan Go apps, as well as the aera® 795/796 and aera 660. GDL 39 collects and stores all available traffic and weather data in your vicinity so it can be available as soon as you turn on your display. It's capable of simultaneously providing wireless data to 2 devices while hardwired to a third. As opposed to using a Wi-Fi® link, Bluetooth® lets you stay connected while on the ground so you can continually receive the latest weather reports as long as you have a data connection — no manual switching of networks required. Just set it up once and it will automatically remember and pair with your mobile device the next time you hop in the cockpit.

A cigarette lighter adapter comes included for onboard power and a wiring harness can be included with your GDL 39 for connectivity to a compatible portable device.

*GPS receiver has a nominal operating velocity range of 0 – 800 kts (411 m/s).

GDL 39 is a non-certified receive-only product. It does not provide ADS-B “Out” capability to satisfy FAA mandate requirements.

¹Not all FIS-B products may be available across all devices. Check your Pilot's Guide for specifics about which products are available on your device.

²Both the audible traffic alerting feature and TargetTrend™ require compatible displays. Check the Pilot’s Guide for specific capabilities available on your display.

³To 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 with a compatible WAAS position source. Visit the Garmin ADS-B Academy for more information.
