 Doug -- several people on the LML list have experience with this system and
its "development". It has been promised for years but the actual performance
and finite testing data are murky to say the least.  Real world counsel might
be to follow the Columbia progress and see what that application ends up being
and what the Feds allow them to put on aircraft and make claims about.
 
 At this stage, Columbia says that the all-electric Columbias will have three
alternators (!) with one dedicated exclusively to the de-icing system. Still
no word on how electrical disturbances to other systems (like avionics) are
being managed, or if any actual icing conditions have been flown and what the
results were IF this testing has been conducted. Maybe all this will have a
positive outcome by the time you're ready, but this turn for the better has
been promised for literally four years.
 
 Bottom line: there is a sadly understandable degree of skepticism about this
initiative at this point, but we'd all like to see them overcome all of the
above and succeed.
