Of course I have which is why I know that the critical angle of attack reduces with the change of the wing profile due to the build up of ice. Doesn't happen alot in PPL training or for that matter in VFR flight. Shall we also include bird strikes as well and FOD or maybe even an seagull crapping on the wing, structral failure in flight?
But as we are talking about GA light aircraft for PPL's which not many of which are cleared for flying in icing conditions your point is rather miss leading and only confuses the issue for 95% of the readers. The other 5% are either instructors or IFR pilots who know the additional qualifications to that statement. So the only reason for your post is not to add any meaning full content to the majority its just to muddy the water and make yourself out as knowledgable.
And yes to patronising walter mittys, I will tell it like it is.
