WARNING:
Do not use the indicated data link weather product age to determine the age of the weather
information shown by the data link weather product. Due to time delays inherent in gathering and processing
weather data for data link transmission, the weather information shown by the data link weather product
may be significantly older than the indicated weather product age.
For each enabled SiriusXM Weather product, the system displays a weather product icon and product age.
The product age is the elapsed time (in minutes) since the weather data provider compiled the weather product.
The product age display does not indicate the age of the information contained within the weather product,
which can be significantly older than the displayed weather product age.
The SiriusXM Weather service broadcasts weather products at specific intervals (defined in the
Broadcast
Rate
column in Table 6-1). If for any reason, a product is not refreshed within the
Broadcast Rate
intervals
(see Table 6-1), the system removes the expired data from the display, and shows dashes instead of the product
age. This ensures the displayed information is consistent with what is currently being transmitted by the
SiriusXM Weather service. If more than half of the expiration time has elapsed, the color of the product age
changes to yellow. If data for a weather product is not available, the system displays ‘N/A’ next to the weather
product symbol instead of the product age.
Table 6-1 shows the weather product symbols, the expiration times and the refresh rates. The broadcast
rate represents the interval at which the SiriusXM Weather service transmits new signals that may or may not
contain updated weather products. It does not represent the rate at which the weather information is updated
or when the Data Link Receiver receives new data. SiriusXM and its weather data suppliers define and control
the data update intervals, which are subject to change.
