In-flight icing incident in Cirrus SR22T (FIKI)

I see, in my 22 NA it is manual !

Although i have not flown an NA at that altitude I am pretty sure that this must have felt like a complete loss of power.

@Peter the carb temperature gauge is in the venturi air stream, not the body. Or am I wrong?! there’d be no point in a carb body temperature indication.

The temperature gauge in my system is in the body, it has a yellow arc which is a temperature range in which — after the venturi, i.e. temperature drop — icing is possible. Thanks to the turbo charger, it is never in the yellow arc and I have never used the carb heat, not in clouds, not on final approach, only during runup.

I believe mine is about the only aircraft with carb and turbocharger besides the Rotax 914

That sounds like a windmilling engine sucking against a blockage. You won’t get zero MP (a vacuum).

11" is slightly less than atmospheric pressure at FL230 (about 12" in ISA). Isn’t that about the MP you would expect with fully open throttle without turbo pressure?

OK, but I would have thought that Aeroplus would have noticed a duff turbo on his next flight.

It is perhaps too easy to generalise. More likely, icing affects different engine installations in subtly different ways.

The strangest thing is that it definitely does exist as an issue, yet how much does one hear about it? Zero, zilch. But then again, as with so much in GA, there are multiple reasons why something doesn’t get reported.

Nope. The stock Commander 112TC and TCA are turbocharged carbs.
Mine isn’t as it is injected turbo engine.

Is it mandatory to report this sort of incident to the BEA/BFU?

The TR182 is not fuel injected? Wow! I was always sure it is. In cars the combination of carb. and turbo was not very successful.

Aeroplus,
will you discuss this on COPA? I would be very interested if other pilots had this experience too. If so this will clearly require some action from Cirrus.

EDIT: found on COPA!

Ah! You guys are great and seem to have a lot of time. I am quite busy with business associates from SA being our guests at the moment. The first thing to do is wait for the read out of all the parameters and an initial analysis of that. On the COPA forum that is also the point where the discussion stopped. It might take some time for the SR22T to get serviced and to get the review back. But as soon as I get something I will update you all.
