Hi, on the ArmA2 i'd took the AV-8BII up to 9.999m and then it began to loose speed and any handling to reach zero speed arround that altitude and then fall in stall; the ArmA2 didn't take that flying height as advantage againist AA as they (all) seen you but only those with AA missiles was able to open fire at you, but, the rest of the AIs keept you tracked no matter what and began to fire once you'd get close enough to the ground. Many aircraft could take a big advantage of bigger flying heights, but at least on the ArmA2... it wasn't that needed for the kind of operations that the planes were capable of or for how booth the AIs and players used to use 'em in SP aswell in MP. But have realistic flying heights for the aircrafts in general would be better than not, IMO. Let's C ya
Yep and a single Tunguska pretty much covers the arc of 10 km. I think fixed-wing aircraft altitude/sub-sonic speed limitations are warranted due to the relatively small map size, but given the OP Opfor in AA ArmA II something has to give, either:
1) Allow Mach >1 speeds for aircraft and/or 15 km+ service ceilings;
2) Expand the battlefield space to make practical use of supersonic jets;
3) Balance the anti-air systems by reducing the area they can cover and/or decrease anti-air missile velocities.
