Well which is the best way to gun down an enemy helo? Because trying to lock the shval ( or however it's spelled lol ) onto the chopper is a right bugger but the only other method would be to fix the cannon/gun but without any type of leading sight that is damn hard especially if your up against a moving target.
Locking up an air target with the Shkval
, setting the proper air-to-air mode, and using the laser range finder to get an accurate range measurement is the most accurate way to place rounds on these kinds of targets. It is a bugger, but, again, proper ingress planning and keeping an eagle eye out for bandits helps keeps things out of hand. If you're at the point where you're trying to snapshot on an aerial enemy, you're in deep doo doo. It can be done, though: here's a vid of me snapshooting Vikhrs on a Su-25 and then a Hind
OK, that said, if you're out of time and need to gun a close-in target, select the cannon without locking up a target and you'll get a fixed reticule on your HUD that you can use WW2-style to aim. It's not as sexy as a gyro- or radar-predictive gunsight, but, again, the Ka-50 wasn't designed for an air-to-air role so it doesn't have the specific equipment required for this role. The fact that we have two air-to-air targeting modes is a bonus.
