A bit off topic for the initial question, but I certainly remember this - quite some years ago now, I trained to do a PPL/IR at Humberside on a Grumman Cougar, equipped with a TKS anti-ice and de-ice system. Lots of training, take off, ask "any ice" every 500' up in the climb and every time the answer was "no-ice"
Then came the day of the IR test, with CAA examiner on board , taxied out, took off, shutters closed and climbing away on instruments - "any ice" I said - back came the answer - "affirm - ice building" - "bl**dy h*ll" - I looked out of the side widow and sure enough there was a lovely layer of ice all along the leading edge - switch on the TKS to de-ice and the next thing was ice coming off the props hitting the fuselage - I certainly learned from that just how quickly ice can build up and I'd never want to fly in any aircraft that wasn't equipped to deal with it.....
But to the OP - fly in winter, it's great, but look for those cold clear days
btw - I passed the IR test!!
