- Both, but you still can get some problems
- No clickable cockpits in 1.6.0, it has "old" Hind cockpit (without gunner seat)
- I think you are asking about EO display symbology for Mi-28, Ka-52 and Ka-50. no other improvements regarding avionics as I remember.
- Main menu freezing, bouncing helicopter, tail rotor damage on the helipad. First two depends on the hardware, but you still have chance to have it.
- Clickable cockpits has advanced avionics for Mi-24 and AH-64D, also some weapon improvements, but it less stable and has more issues.
