3 FIS-B WEATHER AND FLIGHT INFORMATION (345 ONLY)
NOTE
FIS-B weather is only supported if GDU software v12.00 or later, and GIA
software v6.20 or later, is in use.
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 regarding the display of weather data and the associated symbology, refer to
the display operator's guide. Table 3-1 lists FIS-B weather products and the timing
associated with each.
Transmission interval is how often the weather product is broadcast by the ground
stations. Update interval is how often the weather product is refreshed with new data
from on-ground sensors.
