Yes the airbus is like any other aircraft....
I think Airbus should never be considered like another aircraft ! ... is always much more than simply an aircraft ... I think that level of redundancy offered by Airbus cannot be compared with others manufacturers anyway. Mechanical Backup means that sever failures have occurred before; considering a Boeing 737 with the same number of failures, I would consider it as already crashed ! ...
I kept in mind a Triple IRS Failure having a doubt about what should be do in that situation, but when does this kind of failure go to happen ? ... it's nearly impossible !
Best of all,
