Automatic aiming in Hydra is like pressing a handbrake. You no longer have to hold it - just turn the plane towards the target, and it will automatically select it. Turn on / off by key; text informing about the state of the auto-aim.
How to use: Sitting in the hydra, a message will appear below about the possibility of turning on the auto-aim. Press "Beep" to turn on auto-aim, "beep" again to turn it off.
