I flew to Isle Of Wight from Lydd and back the other day and it was -4°. It was a stunning flight. I first started flying in Sweden where we regularly flew in very cold weather. Never had any problems with ice.
Even though there was no moisture in sight on this flight, I did keep the pitot heat going. And I was quicker on the carb heat than I normally am, pretty much pulling it on all descents. Don't think I needed to, but it just felt like a little extra safety.
Question: is there a little temp meter that records the temps at different heights as you climb out? This could be useful as I'm normally to busy to watch a temp meter in the climb (especially on the Cessnas where its up on the corner) and that info could be useful if one should encounter ice.
