Attached are all the SAT's of all aircraft written for IL2 by Joint-ops. Each aircraft has five grades, 1-5 with each succeeding grade being more difficult until grade 5 is mastered. I have personally obtained grade 5 in all allied aircraft and some axis. This is a real good way to self train on a particular aircraft. 
Enjoy

Thanks to all Joint-ops mission builders, Kimo, Bear, Raptor for all of their tireless effort putting these together so that others may learn
