Apart from Concorde of-course.
I have a question that has been bugging me, and I cannot seem to find an answer on the net.
If the two pilots both move their side sticks at the same time (perhaps in different directions) what does the aircraft do? How does the computers know which signal to take?
As previously said, the system is additive with an override function. That's the Airbus system, but do take account of the fact that other designers may well have taken a different approach to it.
Its probably a simple answer for the people in the know (i.e. you guys), but there isn't much info on the net about it!

There are quite a few books however - try the national aerospace library at Farnborough. Or there are a few good review papers out there such as
this, whose references will give you a good trail to follow.
