Mzubair,
PAF F-16s MLUs are not exactly comparable to Bloc-52 versions AFAIK. Chances of the Current F-16s to lock on the MKI is doubtful, though in WVR the pilot's skill-set also gets into play. However in a BVR scenario the Falcon gets outsmarted. The MKI isn't a purely Russian aircraft, the avionics are a mix of Russian, French, Israeli and Indian gear. For example the HUD is an Israeli Elbit unit. So the radar and other avionics in the F16 doesn't offer any advantage as in case with typical Russian Aircrafts.
The quality of the N011-M Bars PESA radar is far superior to any other radar in entire asia. India has got its capabilities multifold by replacing the entire data processor. Radar is very important element in any BVR engagement, obviously the F-16 loses out there. One interesting aspect of the Bars is, that it can, through mechanical and electronic steering, detect a target at 60km in the rear quadrant. The radar was initially designed to detect an F-16 at 140-160kms.
The ECM is also Israeli, when used to its full capability, it will probably perform very well against the likes of Rafaels and Eurofighters, which are better comparisons to the MKIs. The F-16's capabilities were very much kept in mind while designing the avionics and ECM for the MKIs, because the F-16s are very well known to the Israelis, much more than the PAF.
So, even in a hypothetical situation wherein a F-16C manages to see the MKI, and as the fight developes, the aircraft would burn fuel fast in avoiding missiles and manoeuvering for shots, the F-16C would get more manoeuverable faster than the Su30 owing to its smaller size. But the MKI can keep firing in missiles and causing the F-16 to evade. If they got to visual range combat then things start to turn very sticky for the F-16. Though it can accelerate faster by now, but it only has a couple of shots and it is fighting an opponent that can point in any direction to lock on and launch its missiles. In the end the F-16 is going to run out of fuel and missiles and find itself in a fight with an ultra manoeuverable and still heavily armed MKI that can still afford to use afterburner that even has a 2nd crew member to help maintain situational awareness.
The MKI is more a peer of the EF Typhoon and Rafael, neither of which would have much trouble taking out an F-16.
