I didn't fly it in BoP yet, but the in the PC version it was just like that (and probably real life too), it is the ultimate boom and zoom plane, who needs turns anyway?!
1. You take it up to have some altitude advantage
2. Pick a target (hopefully not aware of you at all, since you supposed to be high over head anyway)
3. Extended glide toward the target
4. Intercept target with insane speed advantage
5. Shoot a short burst at the last second (the 4X30mm cannons should rip apart anything in short order)
6. Climb away with you energy advantage (none can touch you, other than an other jet
)
7. Rinse and repeat
Need lot of practice to pull a successful attack like that, need to calculate lead over target, most of the time a rookie 262 pilot will overshoot by a mile. No matter what, don't slow down, if you missed just pull up and climb away, never, ever, ever, ever, slow down to turn fight. once you perfect the technique, it is very rewarding, you'll be untouchable and people will cry
All of the above was from the PC Il-2 experience, so still don't know how it works in BoP but probably similar.
