No trim tabs here. It's FBW.
Just big elevators controlled by the ELACs and SECs, two actuators per elevator, one each side is from blue hydraulics and the remaining two are from green and yellow respectively.
ELAC 2 is normally in control, if it fails then ELAC 1 takes over, if it fails then one of the SECs does.
