Hello @SWSAlexVletsas
The trim effectiveness parameters don’t impact its position.
What I meant is that if you have an asymmetric trim limit configuration like 10° up and 6° down for example, trim position will show 60% when reaching the down limit.
But that also applies to the pilot, it’s not specific to the autopilot.
I’m not aware of any autopilot specific limitation either.
Did you try to adjust your PIDs?
