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.
Products selected for overlay are indicated by a green lamp. Note
that the products in the “Weather Layers” group are mutually
exclusive. 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.
