Your test results are here, Amentes!
Since you doubted that the new sensor's detection range goes beyond the player's view distance, I ran a quick test.
Spawned a Mi-48 above Molos Airfield (few hundred meters in the air to eliminate ground noise for the radar) and took off in a F/A-181 from Altis International (distance Altis International - Molos Airfield: ~15 km). My view distance is around 4250, i could lock that Mi-48 for AMRAAMs at more than 10 km - well above my view distance.
Thought you guys might be interested in this.
