Good grief, what a convoluted load of waffle.
I prefer not to associate ‘legal’ with operating requirements; these may not have the same status as national law.
Any Air Law student can tell you that the Operations Manual is a Legal Document, approved by the relevant authorities when issuing an AOC. Going against the OMA, (except in an emergency) means you're breaking the Law.
The rest of your post is unintelligible to an english speaker. Sorry.
