There's too many posts in this thread from people who think that they know the 330 from a technical aspect when quite honestly they haven't got a clue. A few posts back someone mentioned that the stabiliser has a mechanical backup........it doesn't! The 'steel cable' mearly positions a slide valve and hydraulic power moves the stab.
OK, maybe I was not precise enough. On any airliner sized aircraft, nothing goes without hydraulic power, that is clear. My point with the mechanical backup was to point out, that it is possible to control the stabilizer from the cockpit in case of total loss of electrical supply/FBW-computers. The same is of course valid for the rudder pedals. The rudder is of course also actuated hydraulically, but it is possible to actuate it directly without going through the FBW-computers.
I hope, this makes it more clear, what I meant? At no time did I mean to leave the impression that you could actuate the stabilizer in the absence of _hydraulic_ power. Sorry, if I wasn't clear enough in my first post.
