A fundamental concept of successful IMC flying is understanding the fact that you cannot fly by feel. If there's no AH, then flying off the remaining instruments is possible, however if a pilot's just looking out the window trying to regain references (or ignoring the instruments in some other way), they won't be flying for much longer.
