I can't tell if the current state reflects real life. At least locking in ACM works now and opens up radar gun sight. But only when there is some doppler effect from the helo. For that the helo has to move somewhat fast in relation to ground clutter.
I tried approaching various halos in a test scenario from below so that I have Helo against the sky. ACM radar lock was only possible at ranges <5nm rendering AMRAAMs pretty much useless. I tried shooting Mad Dog AMRAAM at helo but that too is not reliable, sometimes it hits, sometimes it does not. If the Helo stops horizontal movement and just hovers, pointing its nose at you....no chance for any radar lock and very dangerous for you.
I also tried some crazy stuff like diving down on the helo for a gun kill. Then AI sometimes pulls up the nose trying to shoot you with it's gun.
Even 9X struggle with the low heat signature.
