as message type, location and time stamp to handle the

most common type of FIS up-link data.

The different message types and data content are fully

controlled by the ground broadcast systems. The airborne

system will automatically display any message type that is

received.

US and Canadian text METARs, text and graphical TAFs

are available at the same time when subscribed to both US

and Canadian products. US and Candian METARs and

TAFs use the same format as described below.

Selecting Text Data

Green colored Selection Pointers above the smart keys

can be used to select an alternate message for display. The

selected line in the section above the smart keys is noted

by a green circle with an “I” inside. The pilot is able to

move the green Selection Pointer within the lower portion

of the page to select the desired category, location and

time that is of interest with the use of the arrow keys.

Using this interface, the pilot can easily select the desired

message type (such as METAR), then select the airport of

interest (such as KPDX), then select a specific METAR

report by time (such as 141512Z).

At all times, the message displayed in the upper FIS

Message area on the screen matches the highlighted entry

in the FIS Category area below.

The system shows text METAR and TAF data for the 25

locations nearest the present position and up to the 25

locations nearest to the destination in the flight plan that

are reporting weather information. The system will show

all other data provided by the FIS sensor.
