Issues around de-ice on a 182

One of the members of my club has proposed that we add TKS de-ice to our two
182s. Apparently, such a system is to become available later this year.

My reaction at first was negative. After all, in our near-NYC location, the
utility of such a tool is limited to a few months a year. Surely we could
spend money better (ie. on upgades that would be useful year round).

His reply to this reasoning is that our aircraft utilization is much lower
in the cold months than in the summer. If we can increase winter use, then
we get better value from our investment.

It's a good point. Of course, when I mentioned this to my wife, she asked
how much of the lower use was due to the threat of ice, and how much was
due to our lack of love for preflighting in subzero weather.

Another good point grin.

But it does have me wondering. The system would not be "known icing"
compliant. So...what difference in utilization would it make? I'm curious
what others - esp. that fly with de-ice - would reply.

Thanks...
