DATA LINK TRAFFIC (OPTIONAL)

The GDL 39 is a Bluetooth

enabled receive-only data link radio with on-board

GPS, 978 MHz (Universal Access Transceiver frequency band), and 1090 MHz Extended

Squitter (1090 ES) receivers. It is designed to receive, process, and output trafﬁc

(ADS-B air-to-air, and TIS-B trafﬁc information), and weather (Flight Information

Service-Broadcast (FIS-B)) information to Garmin Pilot through Bluetooth.

ADS-B (Automatic Dependent Surveillance-Broadcast) is a surveillance technology

deployed across the United States as the cornerstone of the FAA’s Next Generation Air

Transportation System (NextGen). ADS-B enables improved surveillance services, both

air-to-air and air-to-ground, especially in areas where radar is ineffective due to terrain

or where it is impractical or cost prohibitive. Initial applications of air-to-air ADS-B are

for “advisory” use only, enhancing a pilot’s visual acquisition of other nearby ADS-B

equipped aircraft either when airborne or on the airport surface.
