Last week I had my first IFR lesson in my D100 equipped RV-6. There was a decent amount of turbulence and to say I was in task overload would be a major understatement. I deduced that in addition to learning how to fly off instruments, I was additionally learning how my instruments performed and how to manage the interpretation of them. Most of it just seemed like it would take some time to figure them out. The one that surprised me was the attitude indicator. I had expected this to be pretty stable and tightly track the airplane attitude, especially in pitch.
In the end, I was focusing more on the altimeter in order to hold an altitude, which I know is the correct procedure. However, when I went back to cross check the attitude, it was often not where I expected it and was constantly moving.
The following day was the same light chop (no training & VFR) and I observed the attitude indication as I was flying and holding a stable altitude. I observed the cross hairs going above and below the level line (maybe 2 or 3X the bar width). Through my book training, I was led to believe the gyro-based AI's are quite stable.
I am wondering if this is a by-product of a computer algorithm generated indication and something that I just need to learn how it behaves and therefore how to properly interpret it/average it or is there something going on with my D100.
I appreciate any input on the subject.
