A 330 NWS DEACTIVATION
When L/G is extended manually, even Green hydraulic is available, NWS is inop.
Just question about the reason, which one of the below is correct?
#1 Green Hydraulic for Nose wheel door actuator is shut at alternate extension sequence; same line feeds NWS, therefore NWS becomes inop
or
#2 Nose Wheel Door remains open and this prevents Nose Wheel Steering actuators movement, therefore NWS is deactivated.
Any idea or better explanation please
