At BR 5.0 you can only fight one jet, the P-59, which is a very rare event vehicle that comes up in maybe one out of twenty matches, so I wouldn’t worry about it too much.
With the 190 D you have worse turnrate than the A-8 and the A-4, even when flap maxing, which I will explain briefly here. Basically in the 190s at lower speeds you can drop the landing flaps and then the moment the flap warning comes drop back to takeoffs, and they won’t break because the retraction speed is so fast. This will give a turnrate boost at the cost of losing more speed, which is perfect for when you are trying to reverse people.
At BR 5.0 you have average climbrate so I play it like every other average climbrate plane and sideclimb very slightly to put my teammates between me and the enemy team by between 2-5 kilometers, just so they spot what shows up. However if my team is rushing the altitude with a lot of planes, and the enemy are zerg rushing the deck, I will alter my approach to be way more aggressive so I can get kills.
You are what is known as a ‘boom and zoom’ plane so your main approach to dealing with people at your altitude will be forcing headons and using your teammates as bait. Very occasionally you can bait for your teammates but most war thunder teammates are useless so I only bother with that when flying with someone trustworthy in a squad. To describe headons in brief detail, you want to snap off long-range (1.2-1.5km) shots and see if they dodge. If they don’t, you set up your dodge. If they do, you pop the takeoff flaps so you can lead more, and attempt to mow them down in the headon. The 190 is quite good at this. Just make sure you enter the headon while going fast, otherwise you should probably run instead of taking the headon because you won’t be able to get out of the way fast enough. It’s also very quick at around 5,000 meters, so you can drag people around for a long time.
I would run air targets (maybe stealths if you’re confident) for the 20 mils, and IAI for the machine guns, which will give you a tracer to aim with. They have very similar ballistics. Since you have 250 rounds per cannon you can afford to spray, although obviously if you’re out of ammo / guns jammed midmatch you should reconsider your strategy.
Now more on the boom and zoom. The essence of BnZ is reclimbing after you make the pass. the mistakes that people make are on two ends of the spectrum. The first and most common is that you miss the pass on the guy and then you continue diving for the next guy. This is a bad idea because the first guy will be above you now and give you problems for the rest of the game. You should never do this unless the next guy is CLEARLY stalled out or not paying attention, and you don’t have to dive too far.
Also another version of this mistake is panicking when you overshoot and starting a turnfight with the guy who is slower and on your six. If you already passed him your best shot is to run away and you should make sure you’re quick enough not to get reversed and die before you make the pass in the first place. You aren’t going to be winning that dogfight even against a P-47, so running away while making small rolls and (most importantly) holding the neg-G key randomly for 1-2 seconds is a much better shot at staying alive for the midterm.
Mistake two is on the other end; being too passive when you have a massive advantage. If you’re above a dude in a bad plane and you have all the advantages, press the attack. Break off early if you can’t hit the shot when he dodges, ofc, but keep coming back and don’t give him any breathing room, as long as he’s isolated.
Thanks for coming to my little ted talk. Fw 190 D-9 used to be one of my favorite props. Not anymore but still one of the highlights of the german tree in my opinion. I don’t like any of their other planes.
