5 FIS-B WEATHER AND FLIGHT INFORMATION
The GTX 345 Flight Information Services–Broadcast (FIS-B) function is capable of receiving
weather and flight information. FIS-B is a subscription-free service that is broadcast over
the UAT (978 MHz) data link. Reception of FIS-B data requires the aircraft to be within
range and line-of-sight of a ground station. Because terrain may obstruct the signal, it
may be necessary to gain altitude in order to receive the broadcast.
For information about FIS-B, and Aviation Weather Services and products, refer to the FAA
Aeronautical Information Manual (AIM), 4-5-9 and AC 00-45, Aviation Weather Service.
For information about weather data display and the associated symbology, refer to the
display operator’s guide. Table 5-1 lists FIS-B weather products and the timing associated
with each.
Transmission interval is the amount of time within which a new or updated product
transmission must be completed and the rate or repetition interval at which the product is
rebroadcast. Update interval is the rate at which the product data is available from the
source.
