I don't know that there is any one answer to your question as the factors involved are simply too numerous. Every firing opportunity is going to be different so no one method works for me. I typically try and evaluate the speed and angle of my target, but most importantly, the range. In close (< D200), the travel time of fire is much shorter and aiming less of an issue. Out past D600, the calculation of where to aim can get really "vague" and depends as much on the specifics of the ballistics of the guns as anything else.
If I could offer some tips, they would be:
- always try and get to short range, - try and unload your aircraft before you shoot (ie, stop maneuveirng yourself). It helps with aiming (since you are not in motion) and with judging enemy motion.
- try and change shots that would be under your nose to where you can see the target. Roll the aircraft a bit if necessary so you can get a left to right shot, for example, vs, someone coming from under your nose.
- fire infront of an aircraft and let them fly through the stream.
Other than that, it's more a feel thing. Most people will find their firing ranges are simply too long, making for higher levels of adjustment in order to make a shot. The easiest way to remedy this is to try and get closer and make aiming less of an issue.
