As the other guys have mentioned, its figuring it out from what the airplane is doing. This is as it should be. In real life you didn't get to look into the opponents cockpit and see how they were managing their systems. There is a process of deduction, which is really one of the fun parts of the game.
You get to play detective by deducing from what you see, what the pilot did. You do it long enough and you start to know what is happening in both cockpits, yours and theirs. You start to anticipate the moves and their variations and at that point you'll be winning more because you understand how it works and how it looks to both players. You can start to feed them impressions that lead them astray

This is the same with all martial arts. When I teach fencing I hammer this home again and again. You have to be able to reconstruct what happened. If you don't, your rate of improvement is very, very, very (did I mention very?) slow. Might as well get into the habit now. Once you are in the habit, you probably won't even need to look at the film. You can reconstruct it from where you were and where the bad guy was when he shot you. You can do this because you know the starting position and what they MUST have done to get there.
Enjoy!
