Uat Flight Information Service (Fis) Function - Garmin GMX 200 Pilot's Manual & Reference

UAT Flight Information Service (FIS)
Function
The FIS Function is a graphic weather display
capable of displaying graphical weather information on
UAT equipped installations. Graphical data is overlaid
on the map indicating the rainfall detected by ground
based radar for a specific area. The colors indicating
increasing levels of rainfall progresses from light green
for light rainfall to magenta for heavy rainfall. Review
the Limitations section in the front of this guide for the
limitations that apply to the FIS data. Rainfall data is
color coded as follows:
Brown/Blue
(transparent color)
Light Green
Dark Green
Yellow
Amber
Red
Magenta
Cyan
A cyan checkerboard pattern indicates that no data
is available for that area, and rainfall in that area is
unknown.
When weather data is received, the airborne system
will display that data for 20 minutes. If no new data
has been received for a given area, the rainfall will be
removed after 20 minutes and the area will revert back
to the cyan checkerboard pattern.
The FIS Function is based on a ground-to-air data
link and requires that the appropriate ground systems
are broadcasting weather data and the aircraft is within
reception range of the Ground Broadcast Transceiver
(GBT).
If any weather data has been received in the
Zero rainfall
previous two minutes, the "Service" indicator will
Light rainfall
be displayed in the lower right corner of the screen.
This indicator shows if the aircraft is currently within
reception coverage of a ground station with weather
