Wow thanks for that document m39462! Very interesting to read.
Seems crazy that in turbulence, as soon as you reach A.prot, even if it just clicks over for a second, the plane will maintain it and zoom climb thousands of feet without any sidestick input!
And with AP engaged, the same happens at A.prot +1° as it then disengages AP and enters AoA protection.
I wonder how many airbus pilots are aware of this? I was not, and I suspect I am not alone.
This could even have some relationship with Air Asias recent crash... turbulence followed by zoom climb...
