Takata, you already answered the questions at Post 2125. Sorry for the repetition, but I missed it in my thread search.
The BEA pointed that she was flying at cruise settings Mach 0.82 @ 0210Z and autothrust was ON (self-disconnected at 0210Z); unlikely a 'fortes turbulences' mode which would be at reduced speed to Mach 0.80 and autothrust OFF (like in Air Caraibes case). See my first hypothesis post about the so-called 'fortes turbulences' report issued at 0200Z.
