Hi,all!I just came across this term 'parallel rudder' in the Automatic Flight chapter in PMDG manual.Sounds like a trim compensator or something.But I couldn't find a more specific description in the manual,either in AFS chapter or Flight Control,maybe I just miss something?

Parallel Rudder assists the pilots during Go-Around with an engine out. It’s a bit like TAC on the 777. If no one else goes in to more detail I will post some more info when I get back home later.Regards

Thanks Rob,that's roughly what I dug out from the manual.Looking forward to your detailed info! :(

OK,I finally found where the description lies.It's stated at the end of FD Takeoff part in AFS chapter,thks for help!
