Actually, I am/was one of those know-nothing-non-pilots. I had to learn all those term as well, when i started playing AH (my first flight sim btw). And all that in a foreign language none the less.
Yes, AH has a rather steep learning curve, but hey, its a SIM, not an arcade ego-shooter-click-n-boum.
Some advanced stuff about air combat *is* difficult and needs lots of technical terms related to air combat.
My advice would be: as a *newbie*, start with the basics. Find it at
http://www.netaces.org - lots of articles there explain the basic workings of flying/air combat. Check out
http://www.SimHQ.com for more advanced articles. And, by all means, if you dont understand a certain word/term/article - ASK for explanations. Youll get it, im sure.
Think of it like learning to drive a car. Do you thing your teacher could help you without using termas as 'street' 'steering wheel' 'clutch' 'gear shift' 'turn' 'indicator' 'gasoline' and the like?? So how do you expect people to teach you air combat without using terms as 'Energy' 'Spitfire' 'turn rate' 'aileron' 'trim' etc?
So, i guess what i want to say is: to learn Air Combat, youll have to be willing to put a little effort into it.
