I'd suggest that the aircraft the new boy (or girl) actually flies has little to do with the thing that he (or she) initially learnt to fly, unless it was very similar. To suggest that various skills learnt in a bug smasher are relevant are fantasy. Maybe more relevant in our lives is the ability to write neatly in small boxes. However, given an appropriate course, I can't see a reason as to why a zero houred person can't learn to fly an airliner from scratch. And when the brown stuff hits the rotating circular device designed for accelerating and projecting a mass of air in a certain direction would they be less well equipped to cope? I think not.
