Range matters only when there is full blown war. We lack heavy fighter jet that stays in air longer but right now,we aren't going to fight a war with India,limited war is a possibility. In limited war, capability of pilot and range of bvr missiles are more important. In two front,India has to sacrifice half of its resources towards lac. India is in trouble this time. They can't use all 270 su-30 against us.they will use only 100. There are some technical problems like paf awacs can't refuel in air while iaf can.this is a big disadvantage but I don't think that it's a crucial factor. We can easily beat them. They fly big jets,big rcs.
