ADI precession in steep turn
According to the Boeing book:
"The ADI has cyclical precession in pitch during steep turns. Although the actual airplane pitch attitude remains constant in a perfect steep turn, the instrument indication of pitch attitude slowly varies throughout the turn. Do not rely upon it for pitch attitude other than for small corrections based on short period observations."
This is for a 737-200. I never did see this in the sim which is probably not surprising. And of course, I never have done a steep turn on the real machine.
Has anyone else actually seen this phenomenon on any large aircraft type?
