ATPL air law refs
Just did my ATPL air law exam last week, no CASRs required. In fact, didnt use anything except the CAOs, CAR & AIP.. just as well i didnt shell out for all the IFR charts they wanted me to bring. Print out of the relevant sections of the CAO and CAR was also ok for the exam, though having them in a folder is essential.
Good luck, know where stuff is and you'll be fine.
edit: am not suggesting one should not take the IFR charts in.. i certainly did take ones that i had lying around... there may well be questions that involve them, i just didnt get any.
