Think a PPL holder would have more chance than a non pilot.
As posted before on a similar topic,one of my sons who has a PPL and spent years playing on his home computer flying different sims etc doesnt seem to have a problem.
He has the oportunity at work to go into the flight simulator section and spend a bit of time(if any are not in use).All he was showed is how to set up which airport he wanted.
Since then has flown a dash 8 ,various 747,s and 767 with a total of about 100 take offs and landings etc.
Only problem he,s encounted was landing with a set of wheels in the grass,but thats because he was playing silly b#ggers and set the cloud level too low .
You need the basics of a PPL ,but i wouldnt like to be in the plane unless the guy had comp. sim time and knew the speed and flap settings etc
Having said that i would sh1t myself anyway.
