Hi DB6, the aspect of this that interests me is what happens when rolling G is applied to an airframe at speeds above Va. In other words what happens if a pilot accidentally throws a full aileron deflection and simultaneously pulls a lot of G whilst his airspeed is substantially above Va? ...Surely an airframe can break for twisting forces as well as G?
I am thinking this two thirds G rule that some guys are coming up with surely cannot safely mitigate the additional torsional stresses applied to an aircraft if it is manoeuvred too hard above its advertised Va.
