A320 Rudder Trim & AP.

[AF330]

Hi guys,

A quick question on the A320’s Flight Controls FCOM:
By looking at the diagrams, I understood that while hand flying the bus, side-stick signals directly go to ELAC, which then computes a yaw rate and sends it to FAC, so that we get a coordinated turn. However, can FAC decide to apply rudder trim during manual flight (let’s say, to keep a very long turn coordinated)?

Second question regarding AP and Rudder Trim: FCOM says that FMGC directly computes Rudder Trim value and sends it to FACs. So what sequence do we get here? AP sends signals to ELAC, which as usual sends a yaw rate to FACs. However, FMGC also sends a direct signal to FACs regarding rudder trim?

Any help will be highly appreciated.

Thanks!
