Group.
2) Turn the small FMS Knob to select the GFDS Weather
Data Link Page.
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.
