There is a massive difference between the real thing and a synthetic trainer or sim. So many things cannot be replicated. All the chatter on frequency, weird navaids that each have their own mind...list goes on. You just can't recreate the real thing no matter how hard you try.
Above all the knowledge that if you stuff it in the real game its really going to hurt. In a syn trainer you are always going to be more relaxed.
Do you guys remember the first time you went into IMC in a light twin fully loaded with pax? Try and replicate that feeling!!
I suppose as long as they have passed the aptitude tests then they must be good
