My 2 cents.....
I rarely worry about landing when I head into a fight. Ink already said it but to build skill past a certain point you have to risk your plane. I look at each fight (not just individual but the whole flight) and think about what I could have done better. To me there are a few components or levels of skill in this game.
One is your individual skill in a plane against someone else so: control, ACM, gunnery etc. Then there is the SA portion where you train yourself to see what's going on around you before the you engage so you can see, evaluate and prioritize red guys. As you continue to build skills in ACM, gunnery and control coupled with SA you get to the point where you can actively dogfight while looking around during the fight and recognize and respond to immediate threats and see potential threats building in the future while continuing to dogfight.
The only way to learn how to do all of this is to go do it and then to watch others (ingame or films). If you watch films pay attention to all the info in the film. The really good guys can do all that stuff I listed while getting kills and surviving multi-bogey encounters fairly frequently. Certainly watch what they are doing in terms of their flight style, acm and gunnery. However don't forget to check the box in the film viewer that shows their views. Really pay attention to just how much they look around, even in the middle of a difficult fight. You will see them working for a shot, look back, do some defensive maneuver against another plane in on their six, then go back to the guy they were originally fighting. Some of those films show the pilot looking forward through the gunsites less than any other view.
While practicing this stuff ignore your chances of survival or landing kills. Worry more about good gunnery for quick kills, ACM and threat identification and prioritization (SA)...i.e. avoid target lock and pay attention to attackers so you can evade attacks. I am no expert but I work on this stuff alot and try to improve. The most fun I have in the game involve fights with more red than green. It's constant SA and defense interrupted by a couple seconds of offense for a kill. Basically you're trying to stay airborne as long as possible while still getting kills. Do that enough and you will eventually find yourself surviving until you run out of fuel, ammo or red guys and actually rtb'ing. When the flight is over identify why you survived or didn't survive then adjust accordingly.
Oh and don't forget to leave your ego on the runway. You're gonna die, everyone dies cartoon deaths, even the guys the are really really good. In fact the really really good pilots die way more than you would expect. It's how they got good in the first place. Most of the fearful flying styles and venom on 200 is nothing more than bruised egos. Worrying about player X shooting you down sucking because you just "know" there is no way that guy is better than you will just keep you from getting better because you will be playing it safe. If you aren't taking a risk of losing in a player vs player game then you really aren't playing, nor are you showing any particular "skill" at the game.
OR.......
you can spend alot of time climbing to 25k in the fast plane of your choice hoping to find some guy fighting an enemy (or two or three enemies) and swoop in at 500 mph for the pick. This method is conducive to landing kills. However you will likely also live in fear of seeing a co-alt or higher enemy, more red than green or an enemy in a plane that flat turns better than the one you're currently in. Also be aware it may be one of those really talented folks you are attempting to pick, who saw you arrive, then saw you dive, then evades your attack, forces the overshoot and pops you with one burst as you fly by.
There is nothing inherently wrong with method two....it's just not very fun to me. The beauty of this game is that it's your 15 bucks and entirely up to you how you play. Having tried both methods at different points over the years I have played, I much prefer method one. You will die frequently but a victory under those conditions is much more meaningful to me than low risk flying. Besides there is no shortage of free planes so I say go for it.
