what others - esp. that fly with de-ice - would reply.


Andrew, I am flying a Bonanza with a "not known icing" TKS system out of
Syracuse, NY. From what I understand about the system, the difference
between the not known icing and the known icing TKS system has to do
with redundancy, not functionality. In other words, known ice TKS
system has a backup pump and, IIRC, requires backup electrical.

During flights this past winter when I have encountered unplanned ice,
the system was extremely effective.



I thought the biggest difference was legal, not functional. :-)
