First, I like the new radar set up. Second , many people seem to confuse Radar with DarBar, they are two different things. The Radar shows you the red dot within a radar ring of a active radar. The DarBar just indicates that there is an nme aircraft or a friendly in the sector.
I associated the DarBar with ground spotters that would call in aircraft that they had spotted. Radar of course provided a more accurate representation of the location of the aircraft.
I think that perhaps one improvement that might provide an interesting game play would be if Radar was modeled more accurately as the true line of sight instrument that it was. Giving the pilots the ability to hide behind mountains and use hills to mask their approach. In other words if there is a mountain range between an aircraft and the radar , the aircraft would not appear on Radar until well above the mountain level. Aircraft flying down a valley would not appear on radar unless the radar had line of sight rage down that valley.
I realize that it may not be possible do to coding limitations or complexity. Perhaps another approach could be found to provide a progressive approach to accuracy of the radar. I think that on the coasts or flatlands, within 5 miles of the radar 65 feet is fine, as you more out and away from the radar the coverage is raised. Maybe 5.1-15 miles it’s 200 feet, 15.1 to 20 miles it’s 500 feet. Something to recognize that Radar was not perfect. Also. The way radar is spread out in the game it is only at a base. When it actually was most often a standalone installation. You could have less airfields and more Radar installations. Allow the radar installations to be captured.
