well, beyond the fact that a laminar flow wing may stall with little or no buffeting i doubt anybody can answer how a mach buffeting and low speed buffeting feels in an a330 since on the one hand in normal law the airplane ( as well your company
) does not allow such situations and on another hand every pilot tries to keep away from this. i think we can agree that stalling a widebody is a very serious situation and something other than a cessna 150. surely the pilot of af 447 had other problems than feeling into mach or low speed stall buffets.
