I am IFR rated but not current, and after flying more recently after the purchase of a plane (again... its a sickness), I have been thinking about getting current again. That said, I live in Idaho, i.e. big mountains and MEAs betweeen 10-13k’. When I got my IR I was living in Southern California where the main purpose was to bust through 1,000’of marine layer every once in a while when it’s 65 degrees out. I have always assumed that flying IFR at altitude, in below freezing temps, in visible moisture, like pretty much anytime you would use the IR here in the mountains, is a hard-stop no go and basically assumed my days of flying IFR in a non-FIKI piston single would end when I moved back home. So here’s the question: where do you stand on being in the clouds below freezing in a piston single non-FIKI? Is there any chance my thinking is overly conservative? I almost hesitate to say that - but I guess the reason I’m even thinking about it is when I bought this plane, the seller flew it to me through some really crappy weather, getting up as high as 16,000’ at times. When I asked him if he picked up any ice he said “a little, not enough to worry about”. I asked him if that bothered him and he said “ehh, I’ve been around the block a few times,” and shrugged.
