I'm very impressed by the very low number of users who really understood my question.
How can someone expect a professional and serious answer if so many don't even spend 2 seconds reading and understanding the question.
English is not my native language, maybe I was not so clear in the initial message but I believe I'm not the only one in fault here.
That's obvious that braking a rule (better...braking a limitation) outside an emergency situation is not professional and not even safe.
As those ones, really few, who correctly understood my question said, we are not braking any AFM-FCOM etc Limitation...looking the papers.
I was just trying to find (that's why I asked your help) a document where something clearer was stated because I might have missed it!
