Garmin introduces new ADS-B receiver, expands Flight Stream

3 min read

Garmin has introduced multiple portable weather receivers over the last six months, including the GDL 51 SiriusXM receiver and the combination GDL 52 SiriusXM/ADS-B receiver. Now the GDL family is complete, with the introduction of the GDL 50 – an ADS-B, GPS, AHRS unit with an 8-hour battery. That means you can now choose ADS-B weather, SiriusXM weather, or both, depending on your needs.

GDL 50 with tablet and GPS

The GDL 50 can drive a tablet and a portable GPS simultaneously.

The GDL 50 has the same look and feel as the GDL 52, with a compact footprint that measures 4.75″ w x 3.25″d x 1.25″h. There’s a small flip-up antenna on the back for ADS-B, and our flight testing showed that it works well – we got excellent reception in southern Ohio, even at very low altitudes. It’s a dual band receiver, so you’ll see all the FIS-B weather products on 978 MHz (radar, METARs, TAFs, PIREPs, TFRs) plus ADS-B traffic on both 978 and 1090 MHz.

Traffic can be displayed on the main moving map page, or on a dedicated traffic screen (which can also be a split-screen option). Garmin has lots of sophisticated software to project the track of potential threats, making for the clearest traffic display we’ve seen. As a reminder though, ADS-B traffic is limited unless your airplane has an ADS-B Out transponder installed.

In addition to ADS-B, the GDL 50 includes a built-in GPS receiver to deliver precise moving map location, plus an attitude heading reference system (AHRS) to drive a synthetic vision display. The eight hour battery is a nice upgrade over older Garmin portables, and means you can fly wire-free for a whole day – this is an all-in-one box. There’s also some on-board storage, which allows the receiver to continually download the latest weather and traffic information, then transmit it to your tablet when the screen is turned on. That’s a small thing, but can really extend the battery life on your tablet.

To display all this information, the GDL 50 can wirelessly connect via Bluetooth to two devices at a time running the Garmin Pilot app. This means a pilot and co-pilot could view weather on two tablets at the same time, or a pilot could view it on tablet and a portable GPS for backup. The full list of compatible devices includes any iOS and Android device running Garmin Pilot, plus aera 795/796 and aera 660 GPSs. Older GPS models can be connected with a wire, available separately.

The GDL 50 replaces the popular but aging GDL 39 and GDL 39 3D models, and is available now for $799.

Fltplan go status

FltPlan Go can now connect some some Garmin avionics for ADS-B weather and traffic.

In a separate announcement, Garmin also introduced support for and their Fltplan Go app with certain avionics. First, pilots flying with a Flight Stream 110/210/510 can wirelessly transfer flight plans from the FltPlan Go app to their Garmin panel-mount avionics, including the GTN 650/750 and GNS 430W/530W. Pilots can also transfer flight plans from the FltPlan Go app to the Garmin Pilot app. This is a nice time-saver, especially for complicated IFR routes.

Secondly, FltPlan Go can now display ADS-B weather and traffic from multiple Garmin receivers, including the GTX 345, GDL 88/84, GDL 69, and GDL 52. This is limited for now (the GDL 50 isn’t officially supported, for example, and SiriusXM satellite weather isn’t available), but we expect the list of features and supported avionics to grow over time. It marks the expansion of Garmin’s Connext program, which added some ForeFlight support two years ago.

These new features are only available in the iOS version of the FltPlan Go app, although support in the Android version is expected at some point.

    wouldn’t it make marketing sense to offer users of the older GDL products an upgrade path or a buy back
    offer to move the loyal customers to the newest product ?

    The battery life for a GDL50 is longer than the GDL39/GDL39 3D, it has to be since there is no option for a spare battery. However the 8 hour battery life is an overstatement and inaccurate. 5 hours is closer to realistic expectations.
    More importantly, it is impossible to update the Firmware for a GDL50 because Garmin STILL has not added this to the Datalink list of devices. It also ships with a manual for a different model (GDL51) because they haven’t printed the GDL 50 User Guide.
    The GDL50 is not yet ready for prime time, and Garmin Aviation Support remains unresponsive to their product failures.

    Unfortunately, the Garmin Aviation Support team is completely unaware of this — no one in Garmin knows anything about the Garmin integration with Fortunately, is very helpful.
