When I fail an engine in any of the A320 / 21:
1) with the AP not engaged, I still see rudder being deflected - it shouldn't [rest of the post here should have read: "add all of the required rudder input but rather rely on the pilot rudder and rudder trim inputs to later set it's proper inputs based on pilot's rudder and rudder trim settings"];
2) if I engage the AP and HDG mode, there's no display of rudder trim units being automatically set (central pedestal - rudder trim);
3) only if I use the rudder trim knob (central pedestal) will rudder trim units be displayed.
Would like to see the correct behaviour programmed
Thx !
