Alfa, thank you very much for the detailed answer.
A few more questions popped in to my head.
Target selection : (...most "dangerous" target...), how is that defined? The one that is closest? Or the one that has a radar lock on you ?
And if the second target is automatically selected, that means that I can't manually choose which makes it quite difficult if you are flying together with friends online and engaging a enemy group of 10 aircrafts. Then there is a possibility that you lock on to the same target since you can't choose?
