Maybe I can help, as a newly founded "jet jock", one of the elite who sit in luxurious bliss on a plane that thinks for you and sneers at the mere site of the unfortunate sods that dare to disgrace the industry by flying sculptures as archaic as a prop driven machine!
As far as I can recall when I did my ATP (as a dumb prop driver at the time, now jet extraordinaire and orgasm specialist) and every test and prof check after that, part of the requirement was to know the law and privileges of the license held and how to obtain it. So like a lowly dog I dragged a law book around till I knew what was potting and then did the test.
Does this help?
