I'm well aware of the limitations in the RFM, DK, flying in cloud at those temps wasn't intentional, and I'm not endorsing it, rather to educate through my misfortunate experience.
The question is "Does all flight in cloud below 0 C constitute icing conditions?"
I've always said yes, and avoided it, at least to the best of my ability as forecasts aren't always accurate in my neck of the woods, but it seems I run into more and more guys who claim icing conditions are only those in which you actually pick up ice. in which case, you turn around or take whatever steps neccessary to leave said icing conditions. In my experience the potential for icing is too high.
My post was to answer the question of where can you pick it up, and I've picked it up in a variety of conditions, some unexpected.
