Kharon old mate, its always been my belief that whoever in the bowels of CAsA's rear end wrote CAO 40 should have received a knighthood for penning the most incomprehensible load of gobbeldegook ever devised in the annuls of beauracatese. There has been many who have followed but none that have come close to devising anything as convoluted, incomprehensible and totally valueless as CAO 40.
