JimL, Tees et al - I did understand how the rules work which is why I made the point about no NVFR in the UK in reply to 800's comments.
I don't want to memorise the whole ANO, I have more than enough flying orders to try and remember in the military but I would like to know if you can fly an R22 at night IFR if it isn't cleared for IFR operations. I hope not since they manage to claim enough victims during the day.
