Right, but it's effecting pitch attitude. So maybe the actual pitch attitude doesn't change, though I think considering it's design it would be hoping the pitch did decrease as it's primarily meant to become active in a stall scenario.
No, the MCAS is absolutely not there for the stall scenario. It is to improve manual handling characteristics at flight near the stall. It is not for stall recovery. If Boeing had wanted that, they would have installed a “stick pusher”, which is a simple system, common to many airliners.
From MCAS' point of view, it is effecting the pitch attitude by adding nose down trim. It is "trying to pull the nose down" whether that results in a net effect of the pitch changing or not. Put another way, I would expect that when it's active, the nose would pitching down more than if it was not.
No, it is not trying to pull the nose down. It is trying to change how the plane feels when manually flown at speeds near the stall.
It
can pull the nose down, as we now know, but that was never Boeing’s intention.
