Personally I think if we are going to put folks into the RHS of a jet airliner with a couple of hundred hours or so, they should never be let anywhere near a light aircraft - we need to use all those hours to teach them what is actually relevant to the job they are ultimately going to be doing.
That's precisely what led to AF447, two light aircraft pilots wouldn't have crashed that aircraft, they'd just have flown power and attitude S&L until they could sort themselves out
