I agree with IHL.
When I was first learning to fly a helicopter, on the downwind leg I had a complete mind blank on the pre landing checks. Having a great deal of fixed wing time I did those checks instead. After completing those checks it was enough to unfreeze the brain and without letting on to the instructor completed the correct checks.
I still subscribe to the fact that I would rather have the student ask a dozen dumb questions than make one stupid mistake.
IMHO
