During a GFDS Data Request, the REQUEST STATUS window initially displays “Contacting GFDS...”. Once
a connection is established, the REQUEST STATUS window displays “Receiving Wx Data... Time Remaining:”
with an estimated data transfer time (either in minutes or seconds). If desired, the GFDS Data Request window
may be closed while the data request is processing by pressing the
FMS
Knob; the data request will continue to
process in the background. GFDS Data Requests typically take between 1 to 4 minutes to complete depending
on the size of the selected weather coverage area(s) and Iridium signal strength.
The system retrieves all available Garmin Connext weather products within the selected coverage area(s)
during an initial GFDS Data Request, regardless of which products (if any) are currently enabled for display.
On subsequent requests, previously retrieved textual data (such as METARs and TAFs) is retained if it has not
expired, while new textual weather data matching the current coverage area and all graphical weather data is
transferred to the aircraft during every data request.
