WEATHER OVERLAYS ON MAP
The "Wx Overlay" LSK on the map page brings up a control page on
which the layer combinations can be turned on or off.
Wx Overlay Selection
The options vary with the installed datalink device and subscription
level.
The Wx Overlay page is segmented into groupings of products. One
selection per grouping can be made and products selected are
indicated by a green lamp. The table below represents the possible
set of products available. Products that are not available due to the
device type or subscription level will not be displayed as selectable
choices.
NOTE
ADS-B (FIS-B) US Weather Radar Data is Coarse
When compared to subscription Datalink service data
and even ADS-B Regional data, the CONUS weather
radar data appears as a noticeably coarser depiction –
this is a function of the supplied data.
