Subject to a somewhat aft c.g then (33%) with a/p and a/t OUT..

Thanks! We have heard that the yaw damper is a low-level system that almost certainly would still be functional.
It sounds then that the native phugoid pitch damping is either an a/p function or supplied by Normal (and Alt1?) law.
I'd really like to get at this if I may; what altitude and airspeed range does the A330 (or similar) exhibit if manually trimmed to say FL350 and left to its own devices, at those sort of weights with a somewhat aft c.g. - as I'm presuming it would with a/p OUT and Alt or Direct Law.
