HAZARD AVOIDANCE
SiriusXM and FIS-B weather products are broadcast automatically on a repeating cycle without pilot
intervention. The Garmin Connext weather service requires the pilot to select a manual or automatic (recurring)
weather data request in order to receive weather data updates.
Each data link weather product age has an expiration time. The weather product age is shown in white if it
is less than half of this expiration time, otherwise it is shown in amber until reaching its expiration time. After
a weather product has expired, the system removes the expired weather product from the displays, and shows
white dashes instead of the age. If the data link receiver has not yet received a weather product ‘N/A’ appears
instead of the age to show the product is currently not available for display. This may occur, for example, after
powering on the system but before the data link receiver has received a complete weather data transmission. It
could also indicate a possible outage of a weather product.
The weather product age is shown automatically for weather products displayed on MFD maps. For PFD
maps, the pilot can manually enable/disable the age information.
Enabling/disabling the weather product age for PFD Maps:
1)
Press the
Map/HSI
Softkey.
2)
Press the
Layout
Softkey.
3)
Press the
WX LGND
to show/remove the weather product age information for PFD maps.
4)
Press the
Back
Softkey twice to return to the top-level softkeys.
Tables 6-1 and 6-2 show the weather product symbols, the and expiration times for SiriusXM Weather and
FIS-B Weather, respectively. The FIS-B broadcast rate represents the interval at which the FIS-B Weather service
transmits new signals that may or may not contain updated weather product information. It does not represent
the rate at which the weather information is updated or when the Data Link Receiver receives new data. The
service provider and its weather data suppliers define and control the data update intervals, which are subject
to change.
