or, alternatively, one considers whether the sim might be a useful generic training aid for upset situations .. providing that the behaviour is notionally reasonable. My view is that most pilots,
(a) not having had any exposure will, necessarily, be at a significant disadvantage on the day
(b) having had some exposure will, quite possibly, be in a position where they will have some chance of recovering from some upsets.
Apart from the potential value in upsets, an improvement in the basic I/F confidence and competence is readily observed in the sim. Provided that suitable briefing caveats are given, I really can't see any counter argument ?
