The funniest thing is that The Witch (my ex) extremely aggressively mandates a co-pilot when I take my son(s) up, but when she took them on a holiday they went up in a single pilot single-controls heli, around the G Canyon
My 12 year old son can fly (visual and instrument, incl an ILS by hand), navigate, and land the TB20 just fine. Whether he could do it under real stress is anybody's guess but that argument would apply to anybody else too.
The point I was trying to make is that IMHO the best way to teach somebody to "recover" a plane is probably not how you would teach somebody to get the piece of paper that makes it legal to do it.
