Low N Slow, not a fair test - I can't fly a PC flight simulator for toffee anyway.
But, on a serious point, the reports I read seem to show that by the time your hand-to-eye co-ordination has started to degrade, your ability to follow procedures (gear down? Tank changed? Wind component checked?) has gone completely for a Burton. So, yes a PC flight sim might be used (by somebody who can fly it in the first place), but...
- you want to simulate, say, a moderately complex cross-country flight of an hour or so
- You need to do a good job of simulating the overall flight workload (aircraft management, RT, checks, etc.)
And I'm not sure how well sat at your home PC will do that?
