Figure 6-95 Weather Data Link (FIS-B) Page
When a FIS-B weather product is active on a map, the age of the data is displayed on the screen to the right
of the product symbol (Figure 6-95). 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 transmitted at specific
intervals (defined in the Broadcast Rate column in Table 6-9).
If for any reason, a weather product is not refreshed within the Expiration Time intervals (see Table 6-9), the
data is considered expired and is removed from the display. This ensures that the displayed data is consistent
with FIS-B broadcast data. If more than half of the expiration time has elapsed, the color of the product age
displayed changes to amber. The system displays dashes instead of a product age when a product has expired.
If a weather product is not available or has not been received, the system displays ‘N/A’ instead of a product age.
Table 6-9 shows the FIS-B weather product symbols, the expiration times, and broadcast rates. The broadcast
rate represents the interval at which FIS-B GBTs broadcast 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 UAT.
