I had a student who was WAY to into MSFS. This coming from someone who used to play daily growing up. He had a ton of "hours" flying for a virtual airline and refused to use time compression on a long flight and also would wake up and fly the flight at the actual time the flight was "scheduled" to fly. Like I said... waaaay to into it.
However he was a very good pilot and would of soloed at about 10 hours if it werent for the program he was in that didnt let students solo before a certain amount of flight hours. He had no real time flight experience until starting training with me. His knowledge and flight ability was very good. But any kind of external forces, ie G's, turbulence, wind gusts, etc made him extremely uncomfortable and sick at times.
Guess there are some things you just cant put in a sim. haha
