GFDS WEATHER DATA REQUESTS

The GFDS Data Request window provides the flight crew with the options to enable or disable the requested
weather coverage area(s), choose automatic weather update intervals (if desired), and the ability to send or cancel
weather data requests. The status of the GFDS data request process is also displayed.
Before a GFDS data request can occur, a valid request coverage area must be defined from which all currently
available GFDS weather products will be retrieved. At a minimum, either the aircraft' s present position or a
waypoint (as part of a flight plan or entered directly in the 'WAYPOINT' coverage field) must be part of the request
coverage area, otherwise the request status window will indicate 'INVALID COVERAGE AREA' and the system will
not allow a request to occur.
It is not necessary for a destination (based on an active flight plan), a flight plan, or waypoint to be specified
prior to enabling these coverage areas; however no weather data will be retrieved for these option(s) until a flight
plan or waypoint is provided, respectively.
Requesting GFDS weather data manually:
1) Select the Weather Data Link (GFDS) Page.
2) Press the MENU Key.
3) With 'GFDS Data Request' highlighted, press the ENT Key (Figure 6-59).
4) Turn the large FMS Knob to highlight the desired coverage option(s) and press the ENT Key to check or uncheck
one of more of the following coverage selections (Figures 6-60, 6-61):
• PRESENT POSITION – Requests data based on current location.
