Hi, I tried the F-15C a bit yesterday, and noticed, that I have some issues with finding Air targets. I set up a simple scenario, my F-15 + wingman vs. 2 SU-27 about 200 miles away, on a head on course.
Now I kept scanning for the targets, but they didn't appear on my radar. Radar was in RWS mode and set to 160 range, with the elevation from 0 to 35 (I set the SUs to 25000 ft MSL). First thing happened was the 2 SU radars appearing on my RWR. Short time after that my wingman reported, that he has found the two SUs. and much later they appeared on my radar.
Why did they appear so late on my radar? I'm not entirely sure about this, but I think at the moment, I found them, they were already shooting at me..
edit: tried it after that with a Yak, it also appeared on my radar at about 80 - 90 nm
