It all depends on your experience level. I can only refer to the Australian ATPL, for Captains with heavy command time they gave us a straight swop (apart from the Air-Law exam). The poor Co-Pilots I joined with, although they held the same ATPL, without heavy command time, had to sit the 'Human Remains' examination, as they called it. It was a sore point with them and none of them found it easy.I remember seeing one with a colour diagram of the inner workings of the human lung, when I said he looked like a bloody medical student, I realised from his expression that my life was in mortal danger. I am pleased to report we are still good friends and he is now a 744 Captain with All Nippon Cargo. It placed a lot of pressure on them for no valid reason. The world goes around on bull-!!!! these days.
