No problem, there is a lot of info there but if you want to survive online it boils down to
Speed, Altitude, Surprise, know your aircraft relative strengths and plan your attack by Observe, Orientate ,Decide, Attack.
As painless says flying on comms and with wingmen helps a LOT
We all still do common mistakes and sometimes its good just flying for fun and going into a furball and turning and burning but you wont last long.
