I like the new setting as well. Some suggestions to refine it more:
1.) Show icons on map ONLY if the "spotting" aircraft has actually "seen" (have icon on screen) the enemy aircraft. This way it would be possible to sneak up on an enemy again from low six without him seeing you on the map as soon as you are within 6.0k (UNREALISTIC!!)
2.) Show icons on map ALSO for people that have discoed. I have seen this yesterday and I think it may be exploitable: If you disco from your aircraft, it will keep flying for a while, when you connect again, you jump back into it. However - while you are discoed, your plane WON´T SHOW UP on enemy radar at all! So how to get to your target undetected? Fly towards it, just before entering radar, disconnect. Then time your reconnect so that you jump back in just as you approach your target. Stealth mode!
