BOAC,
on the 'landing roll' when the sim adopts an extreme nose-down attitude to produce a deceleration effect where you are pushed forward in your harness..
Right, like I said, applying brakes changes the perceived acceleration (GIA).
EMIT,
Thanks. I know all that.
EDIT::
Imagine a person swinging on a swing, eyes closed, moving rigidly with the swing, ignoring the wind and air resistance, what does he feel? He feels the rotational movement of his body (the somatogyral effect), he feels the GIA changing in magnitude, but the direction of the GIA relative to his body does not change, until you start braking the free movement of the swing. He could be standing upright without falling off.
EDIT2::

I am primarily responding to rudderrudderrat's post which dealt with the situation prior to stall. I'm not ruling out somatogravic illusions after the stall due to the dramatic increase of drag resulting from the stall.
