ventus45 This research seems to be suggesting that a "conventional empenage mounted HS" at grossly excessive angles of attack (say greater than 30 degrees) can become locked into a "super stall" by being immersed in a fuselage generated wake consisting of two unsteady counter rotating vorticies.
the HS is immersed in / operating in turbulent flow which radically reduces it's control authority.
the A330 is a wide-body, that will generate even bigger vortices
is stall protektion the reason why an other widebody has so much fins between the main-wing-fin and the side-fin?
