Here is one noone has touched yet. I don't see any way you could turn the icons off in aces high for two reasons.
1) In RL Nikis, 109, p51, Yaks, and zeros never flew for the same side. Part of knowing that someone was a bad guy in RL was that big Cross, or Red Sun, Or Star or whatever country marking was on your plane. Also just knowing what kind of plane it was told you it was a bad guy, which brings me to my next point.
2) In RL you could make a better ID at long distances. Now I am not saying you should be able to tell at 6k what an enemey is. But in aces high you are hard pressed to tell exaclty what an enemy plane is til they are 300 yards away, maybe a little further if you use the "realistic" zoom feature. This is a problem with you screen. No matter how high a resolution you run aces in , your screen can't render enough pixels to really represent a fighter in the distance with the same detail it would have in RL. Many of you may scoff at the idea of being able to tell what a plane is at 2k away but here is a test you can try which i have done myself. If you can, go for a flight in a small plane (a large plane would work, but they gain alt so fast) Then look outside the window at the cars below when you reach about 2-3000 feet. You can still tell what many of them are, and you definitly would be able to tell if the had a big swastika or red sun painted on them. And cars are much smaller than WW2 airplanes!
I do think the icon could be improved. I agree with the simple good guy or bad guy icon, as i can usually gauge range by thier size on my screen.
