You have made a factually incorrect post.
Until today, Indian Airforce has never enjoyed technological superiority over their Pakistani counterparts.
Actually IAF had enjoyed technological superiority over PAF pretty much all the time after 1971, all the way upto early 2000s, when BVR capability was acquired by PAF for the first time. That's when the edge began to wear off.
Kargil saw Mig-29s patrolling the Himalayas with Impunity, while F-16s were bugging out as soon as the Fulcrums gave chase.
Now with the coming of Rafales, that superiority will be reestablished.
During the '65 war, Pakistan had Mach2 capable F-104s & upgraded F-86 Sabres armed with Sidewinders, while India used subsonic jet and only with cannons (no operational Mig-21s yet).
IAF had a squadron of Mig-21FLs operational in 65 and they went on CAP as well, but the K-13 missiles they were armed with were unreliable and lost lock easily and there was no underbelly cannonpod yet.
This lesson was learnt and worked upon, and all Mig-21s in 71 had an underbelly GSh-23 twin cannon pod along with the requisite radar ranging gunsight.
In '71, tight stunt even though India had quality aircraft in limited numbers.
False. IAF had similar numbers to PAF in terms of combat aircraft in 71.
And a major chunk of these were Mig-21s by now.
Indian side lost more aircrafts
This is a pakistani claim. Not confirmed. Not verified.
Eastern Sector was completely dominated by IAF.
And Western Sector saw initial resistance, but following the bombing of Sargodha by Su-7s, penetration raids were carried out further and further into Pakistan with runways being out out of commision in the last five days of the war.
