How much time in your training did you spend in actual IMC?
Whenever we could find a cloud we flew in it (apart from the unusual attitudes stuff). And I did a fair amount of my G1000 differences training in cloud - after all, I was going to spend that time looking at the screen anyway.
Probably three or four hours in actual IMC.
When real vertigo hits you and you feel your head is spinning ... you have to go back to basics, do only the most fundamental scan (AI, turn coordinator, airspeed) to convince yourself that the aircraft is in control. Make sure that your AI actually works, though...
Yes, I'd worked out that scanning the AI and the TC should tell me whether the instruments agreed with each other ... whether I'd get it right for real would be another thing of course.
