The FAA granted TSO authorization to Garmin’s GDL 88 ADS-B solution, designed to bring ADS-B out and in capability to Part 23 aircraft flying below 18,000 feet to meet the Jan. 1, 2020 ADS-B out mandate. The GDL 88 receives on both ADS-B frequencies, 978 and 1090 mHz, allowing display of most traffic types as well as FAA-generated traffic feeds. The GDL 88 also includes Garmin’s TargetTrend relative motion technology to help pilots “visualize the trend of traffic threats as it relates to their aircraft,” according to Garmin. For ground operations, Garmin’s Surf technology makes it possible to display ground vehicles and aircraft on runways and taxiways. The GDL 88 is compatible with many types of general aviation transponder. The FAA requires a highly accurate GPS for use with ADS-B out systems, and if one isn’t available, a high-integrity GPS receiver is a built-in option for the GDL 88. Garmin also offers antenna diversity, which helps the GDL 88 detect traffic above and below the aircraft. List price for the GDL 88 is $3,995, and it is approved for installation on a variety of aircraft under an approved model list supplemental type certificate.
