My procedure to kill A/A target is:
- Engage the helmet targeting system and the A/A targeting mode
- Find the target
- keep the shkval (keep pressed key O) in movement until the little circle in the HUD is throught the target
- Lock the target, until you see TA-NA (russian HUD) in the HUD.
- Fire with the gun.
With this procedure, I dont watch the Schkval screen, i keep my eyes on the target.
