Hello,
So ...finally ..after past hours and hours reading from the begining all the posts here (and taking anotations to be able to link things together) I have now a idea where all those speculations and preliminary reports drive...
It's two solutions:
Or it's a misconception of the Airbus system
Or it's a pilot(s) error.
I'm ready to bet my membership of PPRUNE in which direction all fingers will be pointed when the time of speculations will be at his end.
You have sure ..already find which direction.
Regards.
