Asking for A320 NWS system
hello! i am training on A320 CFM engine.
A320 NWS(nose wheel steering) system make me confused.
refer to A320 CBT and some tech books mention NWS is powered by Green on 320,
but powered by Yellow on 318.
however, refer to FCOM and QRH, All 320 family is powered by Yellow.
and 320 system questionary has both answers (1 Q with G and 1 Q with Y).
have asked some friends who flyin 320 already...
some said on G above priority valve, others said on Y below priority valve.
is there anyone can explain this.
