for Display
When a weather product is selected for display on the Weather Data Link (GFDS) Page, a box containing a
symbol for the product and its age (in minutes) are shown in the upper right (Figure 6-56). If weather data has
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 Worldwide Weather product symbols, the expiration times and the refresh rates.
The refresh rate represents the interval at which GFDS ground-based servers make available the most current
available weather data. It does not necessarily represent the rate at which new content is received from
weather sources.
