The GDL® 88 is the first dual-link solution for certified aircraft, including many popular makes and models of helicopters, that not only provides a path to ADS-B “Out” compliance for many pilots, but also brings subscription-free weather and advanced traffic display to the cockpit.
Satisfy the ADS-B Requirements
Under the NextGen air traffic management system, all aircraft in controlled airspace will need to be equipped with Automatic Dependent Surveillance – Broadcast (ADS-B) “Out” technology before the end of 2019. For those who only fly below Class A airspace (18,000 feet) and in U.S. skies, the GDL 88 offers an affordable solution to reaching compliance. And even if you fly above 18,000 feet, the GDL 88 can still give you all the benefits of ADS-B “In” data – consider pairing it with a GTX 330/33 ES transponder for a comprehensive ADS-B “In/Out” solution. With ADS-B “Out”, the GDL 88 gathers information about your position, track and ground speed from either your existing WAAS GPS source or an optional built-in WAAS receiver. It then broadcasts this information to ADS-B ground stations over the 978 MHz Universal Access Transceiver (UAT) frequencies. This gives ATC and ADS-B “In” equipped aircraft a more precise picture of what’s happening in the sky, and allows for more safe and efficient flight routing.
Access Aviation Weather
The GDL 88 also features ADS-B “In” datalink technology that allows it to receive subscription-free Flight Information Service-Broadcast (FIS-B) weather broadcast from ADS-B ground stations on this same 978 UAT frequency. On a compatible flight display, this uplink allows you to view graphical NEXRAD radar, METARs, TAFs, SIGMETs, AIRMETs, NOTAMs, TFRs and more.
Spot Potential Traffic Threats
The GDL 88 can receive ADS-B position reports directly from other aircraft in your vicinity. Because the FAA permits ADS-B broadcasts on 2 frequencies (978 UAT and 1090 ES), the GDL 88 contains both receivers so you can see a comprehensive view of all ADS-B “Out” equipped targets. ADS-B provides the ability to provide air-to-air datalinks with other aircraft. The GDL 88 is compatible with active traffic systems and prioritizes multiple traffic inputs, removing duplicate targets by choosing the highest integrity source available.
ADS-B “In” technology also allows the GDL 88 to receive Traffic Information Service-Broadcast (TIS-B) information. On a compatible display, TIS-B allows you to view the same dynamic traffic picture that ATC ground controllers are seeing.
