Well in "Real Life" Tac, we (well, those of us with 20/20) could tell we were at 325 yards because that's where we could distinguish 10 inch high numerals as numerals and not letters.
10 inch x 2 inch numerals. At 1000 feet.
If we could see like that in here we wouldn't need icons at all.
But we can't.
And I'm so sorry to say this but your comments about visual cues in various threads around here have convinced me you have never really done much flying and looking at other aircraft while doing so. Particularly in the upper altitudes where the air is much, much more clear and visual ranges increase dramatically.
In fact, your comments about visual cues here remind me of your comments about "buff guns" being different and more powerful than fighter guns of the same caliber.
