Ai planes are nearly unvulnerable

You should do a little reading up on basic combat maneuvers. What I found particularly
helpful when I was in the same place you are now, was learning about lead pursuit, lag pursuit and pure pursuit. Once I started using these different techniques I was able to
get into a solid firing position much quicker and more consistantly.

Its genuinely facinating stuff to learn and apply, try it.
