Subscription-free weather, ADS-B traffic and backup attitude

The GDL 39 has been a popular ADS-B receiver for years, delivering in-flight weather and ADS-B traffic to iPads, Android tablets and Garmin portable GPSs. The upgraded GDL 39 3D is even better, adding a built-in AHRS so your iPad can now show a backup attitude indicator. It’s an all-in-one tool that can make your tablet a complete in-flight resource and a potentially life-saving backup.


  • Built-in Attitude Heading Reference System (AHRS) creates a backup attitude indicator on your tablet
  • Subscription-free ADS-B weather, including animated NEXRAD radar, METARs, TAFs, NOTAMs, TFRs and more
  • Dual band receiver (978 UAT and 1090 ES) allows for reception of ADS-B traffic, with Garmin's TargetTrend display
  • Built-in WAAS GPS delivers accurate position data for moving map features
  • Bluetooth connection to your iPad, Android tablet or aera 660/795 allows for two devices to wirelessly connect simultaneously
  • View complete status information in the Garmin Pilot or ForeFlight app
  • Includes rechargeable battery pack (lasts 2-4 hours)

Requires Garmin Pilot or ForeFlight app to work with iPad or Android devices. Requires cigarette lighter cable (included, works with 12 or 24 volt systems) or battery pack (included) for operation.


ADS-B coverage varies by location and altitude – does not work on the ground in most locations. Coverage not available outside US. Not all traffic will be shown; coverage will vary based on equipment and nearby aircraft. 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 335/345 transponders.
