Accessing GFDS Worldwide Weather Products
1)
Turn the large
FMS
Knob to select the Map Page Group.
2)
Turn the small
FMS Knob to select the Weather Data Link Page.
3)
Use the MENU Key to select GFDS Weather, if required.
When a weather product is selected for display on the GFDS Weather Data Link
Page, a box containing a symbol for the product and its age (in minutes) are shown
in the upper right. If weather data has not been requested, ‘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 the following table).
If for any reason, a weather product is not refreshed within the defined Expiration
Time intervals, 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 readout changes to yellow.
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.
