Interesting. I have flown MSFS set to fail systems at random, and
found that I could easily overlook the AI. The one that kept catching
my eye was the DG. Maybe it's because I do not use the AI as a
primary instrument at all - I tend to rely on altitude, DG, and T&B as
my main trio. My best approaches (both sim and hood) have been with
failed instruments.

Kinda have to agree with you Jose. In my instrument training, I never
missed the AI when instruments "failed".

What I did miss the most was the stupid header bug! That naturally was
covered up with the DG, which meant I really had to be on top of my game to
remembering headings rather then "set the bug and forget it".

For level flight, I rely on the VSI. I figure, if it doesn't show me
descending and climbing, then I am "relatively level" and use the turn
coordinator to verify bank information. For heading, I now use my GPS
ground track rather then my backup compass.
