I don't have IFR but was always interested in the concept of "limited panel" which I think is just airspeed, turn and compass indicators, I believe that's how they used to do it in ye olden days. If you can handle that then you're showing some really good skills. So what's "limited panel" under glass, and what would do you do when you discover your plane's comfortably warm interior isn't as waterproof as you thought when it suddenly goes dark?
