Hi FRAX;
Actually, you can find most of what you are looking for in the AIM as far as the class A,B,C etc... The US has been using that for quite a few years now. As to some of the others and what they mean, when you go to your recurrent, ask the folks at the sim center of your choice for any info that they have on international ops. They should have it in their library. I know at SimuFlite, you can find all of this info...
regards
Scott
