@ Dozy
you misunderstood my post, which is probably my fault.
I'm with you in most of your posts in this thread here. My remark was pointed at those, who are either unable or unwilling to understand, that only in direct law the elevator deflection corresponds to the stick deflection, and that it is an basic principle of FBW C* law of AB (at least that's how i see it) that the pitch command of the stick represents an g command blended by pitch rate when applicable.
Therefore it is normal, that the pitch rate change of the increasing thrust enters the equation as just that, a pitch change. If the pilot commanded pitch change corrected by the protections is less than the actual pitch change by thrust, then the elevators will command a pitch reduction despite the stick position.

By the way, a pilot in the loop in a conventional aircraft in such a pitch up situation due to increasing engine thrust would react how (without available protections)? By controlling the pitchup by use of proper stick input, which might be stick forward!
Who wants to end like the B737 at Kazan?
