I saw on Wikipedia that the N001VEP radar in the Su-27SM can track 10 targets at a time and engage 4 of them at a time.
So, what is the symbology of the N001VEP in the Su-27SM that allows it to do this? Because the base Su-27 has the radar symbology on the HUD, and it doesn't seem like this would be possible with radar symbology on the HUD.
Also, why can't they conceivably engage 10 targets at a time if they had missiles?
