If anyone thinks Nigelh's idea is a good one, having an instructor take you into cloud for the experience in your R22, then you probably shouldn' be flying. Go try it in an FNPT2, sure, but even just a quick look-see for real, in an unstabilised a/c, not certificated for flight in IMC (with good reason may I add) with someone who doesn't hold an instrument rating, is a sure fire way to be somewhere you don't need or want to be.
Okay, most of you may not agree but i'm totally against anything like that.
A lot of people lose it very quickly in cloud if they don't have the experience or skills. Forget your hoods which give you soe peripheral view anyway. Nothing like being completely in cloud with nothing to see without that removable hood. When it's for real, and you're on your own, I guarantee you'll feel not so comfortable with your few hours experience. GS hopes to be arranging some SIM days soon for research and hopefully a lot of the ppl's etc will have a try under fairly strict circumstances. Nigelh, can I suggest you have a go too?
