I know this is an old issue but still very frustrating and I thought maybe someone had found an answer. You simply cannot fly when it's hot and sunny. The screen goes completely dark in just a few minutes. So here in Nevada, we're pretty much screwed 7 months of the year. The Tripletek isn't an option for most of us, at least me, and my iPad screen isn't bright enough in general and very glaring. Anyone found a way to fix this?
