SiriusXM is the Active
Weather Data Link Source
When a SiriusXM weather product is active on a MFD map, the age of the data is displayed on the screen to
the right of the product symbol (Figure 6-2). This information can also be shown on the PFD Inset Map.
Viewing the weather product information box on the PFD Inset Map:
1)
On the PFD, press the
INSET
Softkey.
2)
Press the
WX LGND
Softkey.
3)
To remove the weather product information box, press the
WX LGND
Softkey again or deselect all active
SiriusXM weather products on the PFD Inset Map.
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. Weather products are refreshed at specific intervals (defined in the
Refresh Rate
column in Table 6-1).
If for any reason, a weather product is not refreshed within the
Expiration Time
intervals (see Table 6-1), the
data is considered expired and is removed from the display. This ensures that the displayed data is consistent
with what is currently being provided by the SiriusXM Weather service. If more than half of the expiration time
has elapsed, the color of the product age displayed changes to yellow. The system displays dashes instead of a
product age when a product has expired. If a weather product is not available, the system displays ‘N/A’ instead
of a product age.
Table 6-1 shows the weather product symbols, the expiration times and the refresh rates. The refresh
rate represents the interval at which SiriusXM Weather services broadcasts new signals that may or may not
contain new weather data. It does not represent the rate at which weather data is updated or new content is
received by the Data Link Receiver. Weather data is updated at intervals that are defined and controlled by
SiriusXM and its data suppliers and are subject to change.
