FiLtH,
Well, there are several ways that could work. Remember, if he is a mere 15ft off plane, above or below, he'll miss on his FE. Guns can be aimed, so he can still hit you and miss with his fighter.
In the jink at the last moment, let's look at some numbers. If you are bothing going 300mph you have a 600mph closure rate. Say it takes .250 seconds for a change in his course to go from his system to the server to you. In that time you will get 220ft closer to eachother. So, before your FE even begins to register that he has started changing direction you have closed more than 200ft. That is a quarter second that was spent gaining separation on his FE, separation that is only now just begining to show on your FE. If the combined ping time is .5 seconds you would be looking at 440ft closed before your FE began to show his change.
What this also means is that it doesn't matter who's connection is slower or faster. If you have the fast connection and start to evade he won't see it until the data makes it's way through your fast connection and then to his slow connection. Bang, he collides in that time but you pulled clear and didn't. His slow connction killed him just as surely as it would kill you if he'd been the one to avoid and you stayed the course.
Edbert,
Think through the implications of that. You take off, fly 15 minutes to reach my base and, dweeb that I am, I take off, fly one minute and intentionally ram you killing us both. I lost one minute, you lost 15 minutes. You had no way to avoid the ram as it didn't even look like I was going to hit you on your FE. Bad, bad effects on gameplay.
Conversely, if both FEs have to see the ram they will all but disapear and I will now intentionally fly through your aircraft, firing my guns from a range that I cannot possibly miss at, killing you at no risk to myself.
Due to the limitations of light speed the current implimentation is the best possible. To do better we need FTL communication, and that is not something that is going to happen soon, if ever.
