A 320 trimming

A 320.

It is not unusual to fly this a/c with a really aft CG like 36% MAC, when taking off it calls for a AND triming ( e.g. 1.2 DN).

I would like that someone could explain me if are we really flying with the CG rear of the CP ( cause of the nose down trim).
As far as I īve learnt this is not an stable scenario. Even though A 320 is FBW it might be imposible to control in mech back-up if the CG were really behind the CP.
During walk around the a/c, it seems that the THS is inverted chambered, so that it will develop down load forces at the tail even if the triming is for positive angle ( AND).

THANKS.
