G-reg TB2x (full TKS)
is approved for icing conditions.
N-reg TB2x (full TKS)
is not approved for FIKI - because it doesn't have a few bits the FAA requires for FIKI e.g. a 2nd alternator.
Great, isn't it? Perversely of course the pilot of the latter is much more likely to have an IR, so will have ATC working
for him, and is thus far less likely to be collecting ice to start with.
On the rest, well, like I said it is a trade between attitude to risk, and your wallet
There is really only one proper solution: a SE turboprop
Such a shame the TBM is made by ............ the French!!! <gallic shrug emoticon>
