When a weather product is active on the Weather Data Link (XM) Page or the Navigation Map Page, the

system displays the age of the weather data next to the weather product symbol (Figure 6-2). 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 designated Expiration Time intervals (see

Table 6-1), the data is considered expired and is removed from the display, and the product age display is
replaced by dashes. This ensures that the displayed data is consistent with what is currently being provided by
SiriusXM Weather services. If more than half of the expiration time has elapsed, the color of the product age
changes to yellow. If no data is available for a weather product, ‘N/A’ is displayed next to the weather product
symbol.

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 provides 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 weather suppliers, and are subject to change.
