GDL® 88

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.

Traffic Threats

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.

Receive Traffic Alerts
You can still take advantage of the GDL 88’s ADS-B “In” traffic, even if you don’t have a compatible flight display to view the data. When installed in an aircraft without a compatible display, a visual indicator light can alert you when traffic enters your vicinity. Audible alerts tell of a target’s range, bearing and relative altitude (when available). You’ll hear this information through your cabin audio system in an ATC-like spoken format. For example, you might hear, “Traffic: 10 O’Clock, High or Low or Same Altitude, 2 miles.” In most cases, installing a GDL 88 with WAAS can provide a complete solution for ADS-B “Out” while still allowing you to receive some ADS-B “In” benefit — all with a single product.
