toad i like your idea. it sounds pretty good, and you certainly have much more experience looking at other vintage aircraft form a cockpit than i do

as a quick fix, id be happy with just havingthe sea icon settings in the main arena.... 3k instead of 6k. For those that have flown in events with these settings, it certainly makes things more fun.
ive found that from 3-6k i can get a pretty solid id on a con even without icons, especially since all of the same plane types have the same camo. but you have to focus on the con for a second to id it.
i guess my iggest problem with the current id system isthe ability to scan 90 degree segments instantaneously.... in 1/4 of a second you can snap rear (you can even do this while fighintg another aircraft) and confirm (hey i see no red icon, i must be clear) i'd like a fade in of icons of sort, mabye on a linear scare from instantaneous at 0 yards to 3 seconds or so at max icon range.
for the ranges, i would eliminate the precision. i think having range in incriments of 100 yards (ie 1 2 3 for 100 200 300 yards) where the game rounds, would be good enough. we do need some type of range cue imo intil there is some sort of stereo vision for these games.
for radar, i would leave it as is within the tower, except
1) no bar dar behind enemy lines. bar dar should only be over friendly territory. this is to simulate "ground observers" or whatever. i would have this even indicate NOE flights from the tower, a farmer might very well be able to call in a noe airplane flying over his home

2) extend the range of dot dar to 25 miles. from the tower, so fights can still be located easier. 12.5 miles range of dot dar is kinda low. this would also make hitting radar at airfields more important strategically, a plus imo.
3) have hitting the hq kill only the radar in flight, and make it so when the hq is dead, you can still get in tower radar updates by switching to the different individual fields. hitting the hq should not kill the dot radar for each individual field, only the observers(bar). it is very frustrating to log on and not be able to "find the fight" becasue hq is down for 2.5 hours.
in flight--
in flight i would have bar dar only. if hq was destroyed no in flight radar at all.
thats what i would like to see.
