Boxer and Atomic, thanks again !
I understood and appreciated your explanations. I just would like to add something about sidestick : As you said,
the Stick, on pitch axis, demands a load factor (limited to +2.5/-1 or +2.0/0), and neutral position corresponds to 1G flight.
However, i've noticed a little contradiction: In normal law Roll mode, up to 33° bank angle, roll attitude is held if
the sidestick is in neutral position. Therefore, during a turn, neutral position corresponds to the load factor
created by the bank angle (n = 1 / cos(bank angle)) and not 1G as indicated on the manual.
If Pitch mode maintained 1G in a turn, a pitch-down tendency would exist, in order to compensate load factor increase.
