As one who has spent my entire career working on, designing and programming simulators (admittedly my "bit" is the sound and comms bit, just so you get the full picture), any assumption regarding a specific edge-case operation should not be trusted on the sim until verified and checked against aircraft operation OR double-checked against aircraft data (assuming doing it on the plane is either dangerous or really difficult).
GY, thanks for that informed view.
What I can tell from my experiment is that the trim behaved as it did for AF447.
That was the main purpose of the experiment - I will try more when possible - Maybe he didn't trim down for another reason, we don't know, but he did not.
What I'm curious and nobody came with an answer yet, why the trim did stop short of the UP limit for AF447 ? (He did also in my experiment but a bit earlier around 12 deg)
That autotrim up under stall warning is an aberration.
Like Airbus and the concerned authorities not reacting as needed after the well documented Air Caraibes events is also an aberration. Place every 330/340 crew in a simulated exercice of UAS in CRZ configuration and we are suddenly so more 'clever' if needed.
