Mi-24A. When viewed from the cockpit, the ballistic computer does not work and the missiles fly inaccurately.
Hmm, works fine on my end. Try to switch to ATGMs and back (if you dont have them, then try to switch sights settings in multi-functional menu)
Hmm, doesn’t work on my end. Try playing the game and you’ll see its still broken

The ballistic computer is for projectiles with a ballistic trajectory, such as rockets on this aircraft. And since it doesn’t have a ballistic computer, there’s no HUD for rockets in the cockpit view.
And for missiles, you obviously need to use the view designed for them
