IIRC the Bristow cadets did an IFR course at Redhill on the R22, albeit with an instructor always present and were 'examined' by the CAA before being released to main bases.
unlicensed/untrained people
ergo it can be done under the proper circumstances.
Flingingwings; my point is that INADVERTENT IMC should be
'escapable' from' if it isn't, don't go there.
I once flew a 206B up through 3000' of cloud, but I knew it was clear on top and I was current IFR on 2 other Bell types, (one of which had force trim, but not 'beepable'), and I knew that I was climbing over the sea, before turning onto track.
The Whirlwind 7 (S-fifty something) I flew while training didn't have a trim either, but we did manage to get a basic military IR.
BTW, I've never flown the R22 and have no wish to do so!!
