Garmin GDL 88 Earns First Multi-Model ADS-B Approval

 

Garmin GDL 88

January 2, 2013 - The FAA has granted the Garmin GDL 88 ADS-B system the first approved model list (AML) certification that covers most airplanes certified in the non-transport FAR Part 23 category. The GDL 88 is a unique ADS-B system that operates on both approved frequencies and meets the requirements for virtually all airplanes to have an approved system installed by 2020.

The GDL 88 performs the essential ADS-B "out" function by automatically broadcasting the airplane's location, altitude, flight path, and so on. The system operates on the UAT (universal access transceiver) frequency that is reserved for light airplanes, but also corresponds on the 1099 MHz frequency required of all higher-performing and higher-flying airplanes. The dual channel capability provides the broadest possible picture of the traffic situation.

The GDL 88 also provides ADS-B "in" data so pilots can see the location of all nearby traffic. The "in" function on UAT also receives the subscription-free FIS-B (flight information system-broadcast) that includes NEXRAD weather, textual weather, pilots reports, TFR locations, and more.

The GDL 88 has advanced traffic situation display capability that makes it instantly apparent when and if nearby targets will come into conflict with your airplane. Garmin calls this relative motion display technology TargetTrend, and it is a first for any level of ADS-B system.

TargetTrend is important because it's not always, or even typically, obvious which traffic targets will become true conflicts. For example, a faster airplane behind you may be more of a threat than a target of similar or faster speed ahead of or beside you. TargetTrend continuously makes the real-time conflict calculations and visually displays which target will come close, and where that nearest passage will happen. The GDL 88 can also detect and warn of conflicts with other traffic on the ground when taxiing, or while on approach to the runway.

The GDL 88 can use high-integrity WAAS GPS navigators already installed in the airplane for position information, or it's available with a built-in WAAS GPS that operates independently off any other navigators in the airplane. Garmin has also received approval for new software in its GTN 750/650 touch-screen GPS navigators that will enhance performance with the GDL 88 showing weather radar, traffic, and other information. The new GTN software, which is a free upgrade, also allows a GTN to crossfill a flight plan into a GNS 530W/430W that may also be installed in the airplane.

Garmin is now shipping the GDL 88 at a list price of $3,995. Installation of the system provides comprehensive traffic information and weather data now, and meets the ADS-B rules that go into effect on January 1, 2020.
