Hello and welcome to BAT
Are you new to Il-2 in general or do you know the stock game already?
Because that sometimes determines the level of detail you will have to ask for in replies. BAT is "extending" the stock game but the basics remain the same (QMB, FMB, DGen and so on...)
Important, be sure to stay on top of the Expansion Pack updates! Do not lumber around on basic BAT, upgrade to 3.0 and through to 3.5 as soon as you can (there may or may not be a new release in the near future
) -> fixes, updates, additional content!
How modern are the jet?
BAT is an conglomerate of mods that exist as singular downloads. You can find the specifics of an aircraft most likely in these individual download threads. Go there before posting in BAT help.
This question also is a bit funny because we have jets like F-4 Phantom, or Mig-23 or AV-8 Harrier. Of course these come with special Flightmodels. Jet Era in general is very different. The whole process of making a jet fly supersonic is in depth java work. Sweep wings, thrust vectoring... all there.
But you have to find out how to handle these things - but that's part of the fun, right?
In general, it's good advise to deactivate (set to OFF) all the "realistic" settings options when flying in a WW1 or Jet Era scenario, simply because these Flighmodels are so much different than what Il-2 was originally built on. These "realistic" settings are superseded by the java coding and Flighmodel parameters. In a jet or also in a WW1 fighter they only cause unwanted effects more often than not.
(PS: if you are particularly interested in the Jet Era, also make sure you have assigned all the additional new keys, like "misc 1 - 9" under controls....they do interesting things on certain jets, like radar, autopilot functions, IR targeting....)
Are there any kind of Mission or campaign generator that can help me create my own conflict.
Are you asking about Jet Era in particular?
Beecause for "standard" WW2 there's DGen, or the 3rd party DCG. For other eras, no. No "one click generator" - the programming of these databases is an impossible task. Possible in theory but never done. But you can use QMB just as in every era or build your own missions in the FMB. There's a specific BAT missions subsection here on SAS for a reason, you can find a lot of playable content there.
But in my opinion, FMB is one of the most fun tools of the game after all
