Sorry it's taken so long, but I don't spend a great deal of time here.
However, the short answer to your question, CW, is that yes, there are certain occasions where I wouldn't be able to make the strip in my PC12.
Perhaps even ones as unlikely as you suggest.
And I would also say that there are other, unlikely, occasions where you would be in deep poo with your B200!
The only argument we appear to have is whether or not it is "safe" to conduct IFR in aircraft such as the PC12.
(Bearing in mind the only truly safe aircraft is one that is on the ground).
I suspect we will never agree on this, and thus we should respectfully agree to disagree, rather than enter into a slanging match.
I also suspect that, in the long term, you may have to come to terms with single-engine turbine IFR, regardless of what you may think now...
