If you are planning to invest in an installed system then I agree the WSI
system is the best at this point. It is a "transmission" rather than
"request" system so therefore you can get continually updated weather data.
Even more importantly, WSI is an extremely well-established entity in the
weather data industry and therefore it is quite likely they will remain
around for the foreseeable future. Even more importantly, the data
displayed on their weather datalink system is basically the same data as you
can get on the web via www.intellicast.com so the learning curve to learn
how to interpret the data will be much less than with the other panel-mount
datalink providers.

I know of a client/student of mine who uses this system regularly and has
been very pleased, and I saw it installed in another student's plane and he
was similarly pleased with it.


Frankly, if I were to put an installed datalink system in my airplane at
this point then I would be most interested in the WSI system but the main
reason I have not done so yet is because I have an RDR-160 radar system in
my plane and the only current multi-function display which can interface
with that radar is the Avidyne display.
