Then I guess this snipped is not applicable for our aircraft?

Normal.

For future reference, always try to attach one. It helps a lot. 4000 is as far as I saw indeed the wing tank capacity. Did you flip the "Stop Trans (Internal Wing)" switch by any chance? Wing Tanks should still transfer in a normal manner.

Do you have a short track? Because you don't really provide a lot of information, there would be a lot of guessing involved. Check for any switches that switched without you wanting them to switch (check double or unwanted key bindings). Check for damage. Check for random failures being dis/enabled.

I think you have to expand a bit on what you mean. It's not clear, at least to me, what you are on about.

Yes, the "Birds" option is turned on in the mission. It is very likely that this was the cause.

Is late activation enabled by any chance? If yes, untick that box. Also, check triggers. Maybe there are some dependencies of the 190s in regard to some other unit.

Thats why you run a repair, that will remove any mod you installed in the DCS game directory itself.

No, Tacview can stay.

Dust is enabled...

What mission is that? Can you provide a screenshot of the mission's weather setting?

There is a log file in the saved games directory that shows what has been loaded. But generally speaking, if you remove the mods folder in the saved games directory and run a repair, that should make sure that there are no mods present.

It's not MiG-15 related, it happens with all aircraft. If you press a button and then black out or die, that button will be "stuck".

You don't really care about weight. Generally the lighter the better but there is no optimum weight. You just fly the optimum AoA, and the speed will be the result of your weight paired with the optimum AoA. https://f4.manuals.heatblur.se/procedures/landing/visual.html

There is no lamp on the right vertical stabilizer, only on the left one.

Do you have a short track? What mode(s) are you engaging?

Depending on your speed, you turn about 2 or more miles before reaching the desired distance into the arc. And then of course if you see you turn too slow/fast, you can tighten/loosen the turn at any time.

And you also checked your hardware? But just upload a track. Maybe there is more info there.

You can see the trigger being pulled but nothing happening. But it also shows any switches that might have changed or any failures or other things.

Attach a short track.

Did you also check that all guns are selected with the knob on the left wall?

Make sure your anti virus has not removed or quarantined any files of DCS. If it did, restore them and add DCS as an exception. Make sure that you also remove all mods and then run a repair for good measures and then try again.

It's slow because it's bugged. https://forum.dcs.world/topic/366525-f-5e-remastered-fps-issue-after-the-last-patch/#comments

You should check out the official manual too, not just chucks guide. As for the fuze, it literally depends on what you want to do. Shorter fuzes for dive bombing, longer ones for low level bombing or extremely long fuzes for area denial. And the secret ingredient to success is not having someone on your six in the first place.

Nothing changed... Do you also have the fuel selector in the right position? Do you have a short track? You are missing something but with your description it's not clear what exactly.
