I doubt that the PF had time to realize that he was disoriented and acted instinctivly.
Had he been on instruments througout the approach he would not have reacted as he did.
In other words there is a difference between basic instrument skills and recogniing SI, especially during an unexpected transition to instrument conditions
You loose visual, you go to instruments. How much time do you need? If you are unable to do it in 2 seconds, you are in the wrong working place.
That is basic instrument skill. And if you stick to them, there is no need to recognize SI, because it will not happen or it will not affect you.
