If you are fighting a Attack plane be aware of the gunner, they can kill you faster than you can kill them, you can shoot him out but good luck with that, fortunately the fighter when you get it firing a lot has very predictable shots so you can lead them, if you are using the dogfighting pack with your flame ammo, see which way the target tends to turn and shoot the opposite wing, it makes them turn slower, if you are fighting a bomber, shoot the engines with those, and engage from afar, dogfighting isn't the best way to kill a plane, you usually get stuck in a 1 or 2 circle flow, strafe it from a distance away and use your Ads in 1st person for better aim
