Electrically controlled, and hydraulically operated? (A320 question)
Firstly, when saying this, just to make sure I understand it fully.
It basically says that it is electrically controlled in that the signals are sent through computers, which then give feedback, but the operation and movement is actuated hydraulically. Correct?
I believe most things work this way on the 320, however I remember coming across one or two things that were electrically controlled and pneamatically operated.
I don't remember what these things were (if someone can?), nor how exactly it works when its pneumatically operated.
Anybody please explain?
