I posted this in another formum and I repeat it here FYI:
I recently read a disturbing article on one of my online aviation news letters. It concerned a pilot in a Lancair (I believe) who had a glass panel. He entered IMC and subsequently crashed. It seems that his PFD was showing him straight and level but he was actually turning. I can't find the article so my memory is a bit inaccurate. As I recall he also had a glass back up system but the issue was "how do you know which one is telling the truth?" They were able to recover the memory chip and replayed the flight. Ultimately I think they concluded that the magnetometer failed. In the comfort and safety of my living room I wonder what would I do in this situation (assuming crash and burn is not an option). Perhaps the GRT folks would care to comment on this issue.
