I flew with NATO under the "US" type system a good few years ago. The standardisation manual gave the checklists for everything that you had to carry out under every conceivable circumstance... if you did not tick every box on a check ride then you failed the trip! The rule was...if it is not in the book then you cannot do it!
I had a good few discussions with my instructors on many occasions - won a few and lost a few, usually depending upon the nationality of the instructor.
