Garmin GDL 50 Portable ADS-B Datalink Receiver 010-01561-00

Does the Garmin GDL 50 require a subscription for weather and traffic?

No. The GDL 50 receives subscription-free FIS-B weather and ADS-B traffic available across the United States, with no ongoing fees. You get NEXRAD imagery, METARs, and a complete traffic picture streamed wirelessly to your display. This makes it a straightforward way to add datalink weather and traffic awareness to your cockpit.

Does the GDL 50 provide ADS-B Out or meet the FAA ADS-B Out mandate?

No. The GDL 50 is a receive-only ADS-B In product. It displays traffic and weather broadcast by other aircraft and ground stations but does not transmit your aircraft position, so it does not by itself satisfy the FAA ADS-B Out mandate. Meeting that mandate requires a certified ADS-B Out solution installed in your aircraft.

What apps and devices work with the Garmin GDL 50?

The GDL 50 streams data wirelessly through Garmin Connext to compatible Garmin aviation portables such as the aera 660, aera 760, and G3X Touch displays, plus mobile devices running the Garmin Pilot, ForeFlight Mobile, or FltPlan Go apps. This lets most pilots use the tablet or portable they already fly with.

What ADS-B frequencies does the GDL 50 receive?

The GDL 50 uses dual-link technology, receiving on both the 978 UAT and 1090 ES frequencies used for ADS-B. Receiving both bands gives you a more comprehensive view of surrounding ADS-B equipped traffic, rather than seeing only the aircraft transmitting on a single frequency. This is a core benefit of its dual-link design.

How long does the Garmin GDL 50 battery last?

The GDL 50 offers up to 8 hours of battery life on its internal rechargeable battery, making it a dependable companion for long flights. For longer days, you can also operate it from aircraft power, so battery time does not have to limit a full day of flying.

Does the GDL 50 include GPS and backup attitude information?

Yes. The GDL 50 integrates a high-quality GPS receiver for precise position data and provides backup attitude information, which can enable a Synthetic Vision display on compatible devices. Combined with traffic and weather, this adds situational awareness and a useful backup reference in the cockpit on supported displays.

What is the difference between the Garmin GDL 50 and the GDL 52?

The GDL 50 receives subscription-free ADS-B weather and traffic plus GPS and backup attitude. The GDL 52 adds a SiriusXM satellite receiver for subscription-based weather and audio on top of those same ADS-B features. If you want ADS-B datalink without satellite radio, the GDL 50 covers it. Choose the GDL 52 only if you also want SiriusXM weather and music.

Can the Garmin GDL 50 be used outside the United States?

You can use the GDL 50 internationally for ADS-B traffic on the 1090 ES frequency, but FIS-B datalink weather is a United States ground-based service and is not broadcast elsewhere. Outside the United States you keep GPS, backup attitude, and traffic where 1090 ES coverage exists, but you will not receive the free NEXRAD and text weather products available domestically.

What comes in the box with the Garmin GDL 50?

The GDL 50 ships as a complete portable kit. It includes the receiver, a mounting bracket with suction cup, a non-slip glareshield mat, a vehicle power cable for aircraft outlets, and product documentation. With these items you can set the unit on the glareshield, secure it, and start receiving traffic and weather without buying extra accessories first.

How many devices can the Garmin GDL 50 connect to at once?

The GDL 50 can stream wirelessly to two display devices at the same time, such as a tablet and a Garmin portable, so a pilot and copilot can each view traffic and weather. Compatible Garmin portables also support hardwired connections, letting you build a setup that keeps data flowing to more than one screen during flight.

Does the Garmin GDL 50 need an external antenna?

For most installations no external antenna is required. The portable GDL 50 is designed to sit on the glareshield near the windscreen, where it receives ADS-B, GPS, and attitude data through its internal antennas. Aircraft with heated or metallized windshields can block reception, so those airframes may need the receiver positioned carefully or a remote-mount solution instead.
