Yes, the info is in Thom but you must read up well on the ICAO. Also the in my experience the PPL confuser would be good although I used the 'questions and answers book' which is different to the Confuser. This all depends on what set paper you get of course. I think two of the three are hot on ICAO and the Chicago Convention. An example: I can't remember it exactly but it went something like this: Under ICAO laws, do you have to carry your CofR or CofT in the aircraft on all flights? Under ICAO YES, you do. But under ANO As long as the flight terminates at the same aerodrome as departure NO. So you see what I am saying. You really have to read!
