During a GFDS Data Request, the Request Status box displays “Processing...” and the ‘CANCEL REQ’ button
is highlighted. A countdown timer will display the estimated time remaining for the data request. 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 3
minutes to complete depending on the size of the selected weather coverage area and Iridium signal connection
quality.
The G1000 retrieves all available Worldwide Weather products within the selected coverage area 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
downloaded during every data request.
