comparing aircrafts and pilots is like looking at one part of the equation. The other parts are maintainence and pilot availiablity. SUs despite being superior aircraft on paper are very maintainence instensive and despite assembling them locally IAF has limited overhaul capability. India does not even locally manufacture basic items with high turnover like tires. Secondly IAF has severe shortage of pilots, while PAF has almost twice the number of pilots compared to the number of planes. This suggests that PAF will be able to maintain a higher sortie rate than the IAF.
