It frustrating with I know the plane I attack takes 1/2 my ammo and then he gets on my 6 and just with a short burst and I'm going down....
This my issue , how come my plane is so easy , yet the other guy takes mass hits ...
It may sound harsh, but you are not hitting. You currently have a hit% of 0.07... that means only 1 out of ~1400 rounds fired by you hits its mark.
My advice would be not just going to TA, but also setting up a session with a trainer. Usually there are many helpful players there, but not always a trainer, so making an appointment with one of them beforehand may bee a good thing.
Oh, and on gunnery: When in TA, hit ctrl-tab. it will then say "friendly lock enabled" in chat box. If you now hit tab with another player in your view, you will "lock on" and one green targetting crosshair will appear. That will help you to get a feel for leading your shots.
