I don´t think PAF F-16 radars have such a range to fully exploit the Sparrow. Would be useless to have them without the good airplane radars.
We don't have sparrows, but the PAF DID get our F-16s upgraded with the APG-66 radar will can fully exploit the AIM-7 Sparrow and the AIM-120 AMRAAM. That was back when we were silly enough to the think that the U.S. would sell us useful missiles. Its sad really... we had the F-16 primed for medium range combat, but no missiles.
Thats why you might hear "Our F-16s are BVR capable". We have the capability, but no missiles. (The Mirage V ROSE also has a radar with similar capabilities, hence the rumour about the Super 530D).
But atleast it means that PAF trains in BVR scenarios, and when we DO get the SD-10, the transition and using of tactics will be smooth.
