flight model is somewhat "low resolution", radar performances are on point, but feaures are undermodeled, like friend/foe detection is automatic, and you don't have to mess with cone width and scan columns, you have an average default set and that's it, weapons are the same that other platforms shoot.

dcs may seem very complicate, because there' a ot of buttons to memorize, and it indeed is for more modern planes that can switch between ground/air mode, weapon targeting modes, datalink modes etc

but

simplified planes with non interactive cockpit just have a few step to memorize and once you're going, you're going.

like, once you watch and execute the f-15 cold startup tutorial, it's always the same sequence in the same order and sets your plane exactly in the same mode ready for combat.

(nav light management etc is there, but it's kinda optional and not required to learn from the start)

then you get three button for radar mode you actually need (close combat, flood/boresight, beyond visual range), two button to switch weapon, and the rest is the slightly more complicate part, which is radar management

you get a set of buttons to look up/down/left/right, a set of button to move the pip close/far/left/right, a button to toggle scan mode, and a button to lock/unlock a target - it's a lot to set up, but it's quite easy as it has immediate feedback on what you're doing

the rest comes down to actually positon yourself in a way to maximize kill probability and defending from retailiation.
