I guess there's a few differing schools of thought.
1) get in a fight turn and point your nose and shoot the other guy down or die trying.
2) play the game like an arcade game. As you do it over and over you learn what works and what doesn't. You may not know why but hey, its a game.
3) use the virtual physics of the game to establish and fly within the given flight envelope of the planes and use these differences to advantage. In doing so use all available gouges to fly to your planes best advantage against the other guys planes weaknesses. The cornering speed formula is just another gouge.
4) Get completely anal and think the realism is completely real. It's not. It;s a game.
5) Drive a tank. They're alot of fun

Look around and you'll see each of these groups flying.
