john smifff (3 f's I assume ? )

you seem to be intent on confrontation on this thread.

What cozmo has suggested, is in essence correct, his conclusions may not be, certainly a 6000ft climb & 120 degree heading change would suggest that a lack of forward planning was present here (or maybe simply that the higher level was previously unavailable. )

As Despegue has pointed out to you, my comment Re P2F is (as I said ) not thread hijack (but is interesting given the content of the Jetstar incident, wouldn't you say ? )

What I think Ccozmo hasn't grasped, is that the A320 stall margin is (aerodynamically speaking) no less than (say) a B737, merely that Airbus (in their usual cocksure fashion) have (possibly to exaggerate the efficiency/economy of the machine) chosen to leave a smaller margin when flying at Optimum/Maximum than Boeing have with the 737. This has nothing to do with aerodynamics & is a choice by the manufacturer , not corrected by the certifying authority I would suggest.

As a serial Airbus basher, I find deeply disquieting the reports about Alpha Prot etc above, I have never been a great believer in having to reach up to the overhead panel & fumble for switches to regain manual pitch control (I assume that is the Airbus drill for that ? ) , god knows how they get that one past the certifiers .
