As far as a range indicator, I think its NOT needed. At all. Use + and - icons next ot the plane name to show your rate of closure. I say this because you can tell the distance between you and your target by using simple eyesight..if its a dot then its beyond 6.0 , if its in d4.0 or closer you use your gunsight to compare the 'size' of target to your own gunsight...just like real ww2 pilots did.
I doubt very strongly that "real" WW II pilots turned nose to every target to get the object in question into the HUD view to compare the size of their target.
Simply using eyesight ... How would you like to give me your eyballs to use cause mine are old and tired and suffer from presbyopia. I wasn't wild about the new AH II icon system but was willing to live with. The + and - have now made it a much more enjoyable experience for me, but forget about what I need or other that may suffer from old eyeballs and maybe worse. We all need to bow to the "realism" junkies so that THEY can enjoy the game.
You know what ... Hit CNTRL-I until it says "Icons Off". That should make it more enjoyable for you without impacting anybody elses enjoyment.
Or something similar. I just dont like to be given instant info on everything around me..it makes for poor gameplay since it removes the ability of the 'bounce' because in AH1 and now even in AH2, all you need to do is do snap-views, scan each view of the sky for like .1 seconds and one instantly knows that 2 of the 3 planes behind you are enemy and are at X range, above and to all sides theres X number of enemies and their exact info... it just no fun at all.
There is no other sim out there that can even compete with the naturalness of the AH view system. I can assure you that I can move my head around in RL as fast as I can in AH so there is nothing wrong with the implementation IMO. As far as all the info one can glean from their views ... without that, this game is dead. Again, if it doesn't suit YOUR needs, then turn the icons off and have a blast, but don't presume that your idea of fun is exactly the same as mine.
Again, in ww2ol even with their ****ty flight model, its the icon system that makes the game so immersive in the air.. that dot on your 3 oc .. squint your eyes at it for a few seconds and a pale icon comes out and lets you know if its hostile or not..but no exact info on range or anything.. but whoa! con at 9 oc is enemy! You turn to it, you realize you are closing on it (target image becomes slightly larger) dive under his wings to come up from his belly... and all the time the enemy pilot did not spot you ..all because he was not able to snap view to his high 3 oc and instantly see the big bad enemy icon..he was jumped. and died because he had no wingman that helped him scan the sky.
Again, I don't get the problem with the views. Are you saying that in RL if I was attacking at my 9, his 3, if the spirit moved him, he could not snap his head to his 3 and see me coming. Was there something attached to the helmets of WW II pilots that prevented them from scanning the skys as fast as there neck would allow ?
