I'm totally in favor of experimenting with the icons. Right now, they are a bit overdone. Here's a few of my previously posted thoughts...I haven't changed my mind much since then.
Here's a few points to ponder. These thoughts are based on a non-historical arena, where all sides fly all planes. Strict Historical could/should be different.
Ranges would have to be hashed out but that's an area that affords easy experimentaion once the overall system is set.
1. At long range, a plane <whether friend or foe, fighter or bomber> should just be an unknown dot.
2. As range closes, one would be able to distinguish a dot as a bomber earlier than a fighter. Therefore, some sort of "buff" ID should show at a range that would still be a dot for a fighter. At this range you couldn't tell friend from foe.
This means a dot could be either a long range plane of either type or a closer fighter that is not yet distinguishable. You just couldn't tell.
3. As range further decreased, some kind of "fighter" ID should show that would be different from a bomber. You should also now be able to tell, in some way, friend from foe, perhaps just a red dot at nose, tail and wingtips. This assumes that we would <in Real Life> be distinguishing plane type. Again, this would be a different range for a bomber than a fighter.
4. Now, after IFF range, add distance information. Range info should perhaps only be shown in 1k or .5k increments to avoid the rapidly running counters. I would not show range beyond a certain distance <a yet to be determined "threat" range> and I would remove it as the aircraft comes to "guns range." Absolutely cut out range info inside of 1k (essentially max guns range). You need IFF here, but you don't need range when you're ready to shoot. That should be part of pilot skills and judgement.
5. I would have no aircraft type ID available at ranges that allow you to distinugish that info from the graphics. (determined for the lowest resolution avail). I would allow some simple "type" info at ranges where you could see it in real life but not on a monitor.
Different colored dots, arrows, numbers...any of these could be used to provide this type of information while minimizing and shrinking the huge icons we now have.
I hope we do experiment!
