Got asked at an interview last year about what sort of redundancy control does the Airbus340 have. I struggled with an answer, and was told that I'll have to do more research into that for my next interview. After walking out i felt a little silly cos the
thing is fly by wire. So is there any redundancy in the control surfaces?
What about The RAT (Ram Air Turbine), what does it power?
That next interview is just around the corner and thought I had better make an effort in finding out some answers, btw it was with Cathay.
