The aircraft decided to pitch down (at around -.8 g) all by itself. Twice. In so doing it overrode the pilot input. You can thank Airbus for this one.John Bartelsnoreply@blogger.comtag:blogger.com,1999:blog-11124940.post-51316197613011673532008-11-19T14:03:27.124-10:002008-11-19T14:03:27.124-10:00The ATSB continues to explain the QF-72 accident cause as an Auto- Pilot or a on-board computer failure!<BR/><BR/>These same type of accidents have been occurring worldwide and will continue, unless the true cause is recognisd and the proper pilot training is iniated!<BR/><BR/>The pilots are instinctively reacting to a weather induced, strong, updraft, which rersults in an abrupt nose high attitude transition!<BR/><BR/>This mechanical(no flight control input) maneuver is completely unexpected by the pilot and he reacts by shoving the nose back down, to avoid what he considers to be a possiblr stall threat.<BR/><BR/>It is this maneuver that projects the unbelted passengers, in the rear of the aircraft into the ceiling.(longer moment arm, from the center of gravity)<BR/><BR/>We cannot blame the pilots as they have not been advised of this problem, because the Aviation Industry itself, is not aware of this phenomena!<BR/><BR/>A quick training session will bring the pilot's up to speed and resolve this threat to flight safety!<BR/><BR/>William J.
