Weather
Product Age
Display
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. 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.
If for any reason, a weather product is not refreshed within the Expiration Time intervals, the data is
considered expired and is removed from the display. This ensures 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.
The following table 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.
