Thesandbox - In response to your second question;
No quite simply. The joystick has no feedback. Even if the plane was all over the place, the joystick would not move at all. There is no feedback. Of course, I haven't flown a 'bus in severe turbulence in direct law, but as you were asking about the fact that you can't use your "body strength" etc then it makes no difference as there still isn't feedback.
