good question
how about asking if that G load exceeds the AOA known to stall the wing?
having watched videos of the Russian S30 doing instant vertical pitch -to produce a flat plate moving thru the air - (the plane is moving 90 degrees to normal flight angle,horizontally) I also wondered where the absolute G load calculation could be determined.
we do these maneuvers routinely on our models but of course they are impossible as proven by volumes of known fact (yawn), etc., etc.,
