not been requested yet or is not available, ‘N/A’ is shown next to the product symbol instead of age. The age of
the weather product is based on the time difference between when the data was assembled on the ground and
the current GPS time. Weather products are updated continuously or refreshed at specific intervals (defined in
the Refresh Rate column in Table 6-5).
If for any reason, a weather product is not refreshed within the defined Expiration Time intervals (see Table
6-5), the data is considered expired and is removed from the display. The age of the expired product is replaced
by dashes. If more than half of the expiration time has elapsed, the color of the product age changes to yellow.
Table 6-5 shows the GFDS weather product symbols, the expiration time and the refresh rates. The refresh
rate represents the interval at which the GFDS servers make available the most current known weather data.
It does not necessarily represent the rate at which new content is received from weather sources.
NOTE:
The availability of specific weather products varies from region to region. This Pilot’s Guide shows
all weather products, regardless of availability in a specific area.
