DATA LINK WEATHER (FIS-B) (795 AND 796)

NOTE: The Flight Information Service (FIS-B) weather data provides information
for avoiding hazardous weather. Do not use FIS-B information to penetrate
hazardous weather.
The aera 795/796 is compatible with the GDL 39 data link radio. The GDL 39 is a
Bluetooth enabled receive-only data link radio with on-board GPS, 978 MHz (the
®
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 the aera 795/796 through a power/data cable. As a UAT receiver,
the GDL 39 can receive and, when connected to the aera 795/796 , display Flight
Information Service-Broadcast (FIS-B) weather products as well as traffic.
FIS-B is a free weather service that is broadcast by Ground Based Transceivers
(GBTs) over the 978 MHz UAT frequency band as part of the FAA's Next Generation
Air Transportation System (NextGen). To receive FIS-B weather information, the GDL
39 must be within range and line-of-sight of an operating GBT. Reception may be
affected by altitude, terrain, and other factors. GDL 39-supported FIS-B weather
products include METARs, TAFs, NEXRAD (Regional and CONUS (Combined)), AIRMETs,
SIGMETs, PIREPs, and Winds and Temperatures Aloft. Other products include NOTAMs
and TFRs.
