I haven't got all the facts at my fingertips as I sit here now, will go over the info I have when I get the chance but 447 seems to tie in with the A320 LOC when carrying out an acceptance test flight for the return of the aircraft to service with Air to New Zealand. As I recall, an unplanned approach to the stall was carried out, as IAS was reduced, the aircaft systems trimmed the tailplane full nose up, just before the stall, the engines were powered up, but due to the up trim and the nose up pitch caused by the engine thrust lines on pod engines, the aircraft did not respond to recovery nose down side stick input as was expected. This caused confusion resulting in a relaxing of the nose down input. The aircraft subsequenty stalled and crashed into the ocean.
It seems to me the synthetic feel of the sidestick was an issue, can't help but feel a good old Boeing style yolk would have removed all doubt of what control input and to what extent, was being made? Would like to have a go at a sidestick if I got the chance, as I do regard them with some suspicion...along the lines of, it's all good as long as things are ops normal
...but when things are going wrong...
