Pool,
I beg to differ with you on this one:
Redundancies are here to exclude failures
If redundancies are to exclude failures, why is it a redundancy then ?
The whole concept of a redundancy is primarily based on the concept of failure. The pilot is not a system, it is liveware and not hardware such as ADRs etc etc...
The pilot carries a redundancy due to his/her Training/Experience/Skills but i am afraid that is even a more limiting factor at times...a topic in itself.
The same way redundancy is built into systems, protections must be included in the most extreme combinations of failures. I am not asking for more protections. i am asking for the same protections available under more extreme failures or comibinations of thereof.
Afterall it is FBW as you stated. So it is either a fully functioning marvellous system or a backup mode that makes you recover and fly the plane like a conventional one.
