Bruno,
Your dilemma reminds me of an old Tommy Cooper joke..."Doctor, Doctor, every time I poke myself there it hurts?" "Well don't do it then Sir!"
Seriously though, we had a chap who had to leave commercial flight school because he was continually ill. Bear that in mind if you want to go the whole way with flight training.
Have your eyes tested also. If your sight is deteriorating without your knowledge then that could possibly be the reason.
i was talking to a sim instructor in NZ wen i did my license and he told me that some studends get sick in the sim. this is however a full motion sim or whatever the call it. it just amazed me how reall they must be. But than he may well have been pulling my leg. anybody any knowledge on that?
Yes, if the visuals are out of synch with the motion then then it's curtains for everyone who's inside
