I would be wondering, whether this thrust vector control thing..TVC..will make any difference in 1-on-1 dogfight? lets suppose SU-30MKI vs F-16 block-52.
It does but keep in mind that the USAF F-16s flying at CI-05 were not JHMCS/9x capable or even simulating that capability. You can definitely get your HMS to cue a weapon against a TVC capable aircraft because you can see him before he can pull something nutty with his Thrust Vector Controls. With AIM-9x and other HOBS AAMs, your engagement envelope is that much greater to engage a TVC equipped aircraft.
