Hi folks,
after some Oceanic flights, I decided I could do it professionally

, but how to do it really ? I found a very good tutorial inside the IVAO training center, but it misses the main point !
It says, that the NATs are changing and declared on a daily basis. But where can I get the current NAT tracks, and can I be sure, that the ATC also knows them ? So, how does it work really on IVAO ?
