Still confused about whether you’ll need an ADS-B receiver that’s capable of operating in the 978-MHz UAT or the 1090 MHz frequency band? Garmin is making that discussion more or less moot for the vast majority of us with the introduction of the GDL 88, the first FAA-certified ADS-B receiver capable of receiving both frequency bands.
Announced last summer, the product has just received FAA TSO certification and a blanket AML STC, allowing Garmin to start shipping the $3,995 unit. The GDL 88 brings the benefits of access to advanced traffic information and subscription free weather for aircraft flying at any altitude, as well as compliance with the FAA’s 2020 ADS-B mandate for aircraft flying below 18,000 feet in the United States.
