I retried this failure this time with the HYD PRESS SYS 3, at this time, AP "R" was unservicable, according the QRH and your schematic, it should be AP "L".If SYS 1 fails, AP "C" is disconecting, which is correct.

Also with the HYD SYS 1 failed the nose gear steering still works. For example applying rudder nice and smoothly to max deflection (left or right) the aircraft responds normally upto max deflection.

And with HYD SYSTEM 1 failed the rudder no longer works.

Hi A32XThis is not correct, the Upper Rudder is also feeded by SYS 3, and the Lower Rudder is completely independent of the SYS 1 (feeded by SYS 2+3)

Gents,Lower rudder should stop working with HYD SYS 2 and 4 INOP. Upper rudder should stop with HYD SYS 1 and 3 INOP. That's how I read Nick's schematic and that is how the sim was modelled lat I checked.As far as nose wheel steering is concerned I have INOP steering (both nose and main) with HYD SYS 1 INOP. Hope it helps,
