DATA LINK WEATHER (FIS-B)
WARNING:  Do not use the indicated data link weather product age to determine the 
age of the weather information shown by the data link weather product.  Due to time 
delays inherent in gathering and processing weather data for data link transmission, the 
weather information shown by the data link weather product may be significantly older 
than the indicated weather product age.
  
WARNING:  Do not use data link weather information for maneuvering in, near, or 
around areas of hazardous weather.  Information contained with in data link weather 
products may not accurately depict current weather conditions. 
The GDL 39 can also receive and, when connected to Garmin Pilot, display Flight 
Information Service-Broadcast (FIS-B).  FIS-B is a subscription-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 factors including altitude or terrain.  
GDL 39-supported FIS-B weather products include METARs, TAFs, NEXRAD (Regional 
and CONUS), AIRMETs, SIGMETs, PIREPs, Winds and Temperatures Aloft, and NOTAMs 
(including TFRs).
Viewing FIS-B Weather product and Ground Station Status:
1)  From any page touch Home > Connext.
2)  Touch the ASD-B Tab. 
FIS-B WEATHER PRODUCTS
FIS-B weather broadcasts are updated regularly and may take approximately ten 
minutes to transmit all available weather data.  Therefore, not all available weather 
data is immediately available.  No pilot action is required to receive FIS-B weather 
information.  Weather product status can be viewed on the Settings Page under the 
GDL 39 tab.
When a FIS-B weather product is active on a map or in a Weather Widget, the age of 
the data is displayed.  The age of the product is based on the time difference between 
when the data was assembled on the ground and the current GPS time.  Garmin Pilot 
combines the CONUS and Regional Radar into one map overlay, the time shown is for 
the Regional Radar product only.
