The Term SOP is long in the past. It's OM B nowadays and speaking of EU legislation part of the legally binding operations manuals. SOP is a mere recommendation of the manufacturer nothing else. OM A creates a legal framework for operations, something like main law body and is tightened up to the AOC specs. OM B is the executive order if you wish of how to comply with A using a tool such as aircraft. C are aeronautical manuals such as charts. D is training. A clever pilot knows his legal framework and understands the implications of such along with the consequences. On daily basis there's millions of violations all around the world but as long as everything ended well, legal machinery is in hibernation. As soon as the sh&t hits the fan that's when the merciless giant awakens and slaughters the scapegoat without compassion or remorse. Luckily religions aren't part of legislation anymore.
