Please note my use of the word "roughly" Not many folk seem to know about this feature because there seems to be a lot of confusion about it whenever I mention it. I am just off to work, but when I get back I will try to reproduce the diagram in the manual which describes what I am talking about.
Capot; An Airbus is an aeroplane flown by 2 PILOTS. There is NOT a "total dependence on computers". There is a lot of automation available, but there are also extensive procedures and back-up systems should anything go wrong. If ALL the computers were to fail, the PILOTS can still fly the aircraft and recover enough systems to make a safe landing. The high level of automation available produces a modern, efficient, safe, and comfortable flight.
