Once it was known that the Indian Army was knocking at the gates of Dhaka, the PAF in the West virtually gave up flying. During the last few days of the war, the IAF brass ordered attacks on PAF airfields with the sole purpose of drawing out their aircraft. But that rarely succeeded as the PAF aircraft for the most part remained secured inside their pens, refusing to come out and fight. The strongest indictment of the Pakistani Air Force was made not by an Indian but by the Pakistani leader, Zulfiqar Ali Bhutto, who took over from General Yahya Yahya Khan after the 1971 defeat. On taking over, he made a speech in which he castigated the PAF chief Air Marshal Rahim Khan and several other officers by name.
A better analysis of effectiveness of the two air forces is provided by the losses per sortie figure. The IAF flew at least double the number of combat sorties per day than the PAF, thereby exposing itself to ground fire and enemy interdiction. Despite this, the IAF's attrition rate of 0.86 per 100 sorties during the 1971 War compares favourably with the Israeli rate of 1.1 in the Yom Kippur War. The PAF's overall attrition rate works out to 2.47 (including transporters and recce aircraft lost on the ground). If aircraft destroyed on the ground are not taken into account, the rate works out to 1.12, which is still very high given that PAF aircraft never really stood back to fight.
The question of loss is important but, in the ultimate analysis, secondary. Achieving air superiority cost the IAF dearly in 1971 but in the end it managed to achieve complete dominance over the skies in both East and West Pakistan.
