FWIW, I've not attempted any 'proper' panels yet and the instruments that I've included on the panels I've done so far are more for monitoring what the a/c is doing, rather than being designed for flying the a/c. As such, many of them do not use data from the 'instrument' sub-system but show absolute readings from the property tree. I'd like to do 'proper' panels and instruments but until I have a better understanding of how they work and how they're used, in real-life, I'm holding off trying any.
