back when I was a ppl which is a long time ago I was flying with another ppl in an r22 from shoreham to sandown IOW he was flying but we had the cyclic in on my side so I could help with the radio. About half way there we saw sea fog in front of us and decided to turn around but we where too late and it formed around us and we went imc.
my friend could not do the whole lot so i took over the cyclic he pulled full power and we climbed out the top headed back to shoreham by which time the airfield was in fog so we headed to blackbush.
I have never been imc in a 22 since and will never again I hope, it is not something to be done lightly and I think we had a lucky escape.Imc should only be done by those with currant IR's as look at what happens to some evan in suitable heli's.
