When a weather product is active on the Weather Data Link Page or the Navigation Map Page, the age of the
data is displayed on the screen (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 30-, 60-, 90-, or 180 minute 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 broadcast by XM Satellite Radio services. If more than
half of the expiration time has elapsed, the color of the product age displayed changes to yellow.
Table 6-1 shows the weather product symbols, the expiration time and the refresh rate. The refresh rate
represents the interval at which XM Satellite Radio 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 XM Satellite
Radio and its data vendors.
