rd-93 is a good engine compared to f7 and mirage engines (aircraft its replacing), the problem lies with thrust and ab thrust which is GReater then 2 lb for each lb of thrust generated, compared to western engines like ge or even al-31 (1.7 or 1.8 lb/lb in ab wand .67lb /lb in dry thrust)which is less then 2 lb per lb of thrust. Tbo has been improved but not near western engines, but its 1/2 the prices of any western engine too. So cannot have it both ways. I think best way is to improve internal fuel capacity of if-17 from current 2330 kg to say 2700-2800 kg like mirage 5 or other fighters in the class if it is some how possible, ie better fuel fraction, with external tanks it fuel load is good.
Arsalan you are forgetting RD-93 issues with such load configuration.
What most people here is not considering is that the load is just not about weight but additional drag.. caused due to extra weapons.. and things like drop tanks... while most people consider the drop tanks along 4 BVRs along with 2 WVRs a good configuration must understand that without proper ECM pod and jammers all 4 BVRs are a waste against enemy like IAF... no I am not praising IAF here.
Besides RD-33 has been quiet reliable for its 1st 220 hrs... however engine shut down is an issue with the engine... I'd love to have an detail insight of the JF-17 crash accident.. and not the Bird story incident.
Buddy main problem is not Rd93 Engine...Actual problem is what other option they have other then Rd93.....and that to some extent is the biggest advantage of PAF and Jf17.....I mean they know that they have limited budget and limited options so they don't think twice for going for those options....What most people here is not considering is that the load is just not about weight but additional drag.. caused due to extra weapons.. and things like drop tanks... while most people consider the drop tanks along 4 BVRs along with 2 WVRs a good configuration must understand that without proper ECM pod and jammers all 4 BVRs are a waste against enemy like IAF... no I am not praising IAF here.

If you are placing a smaller package of JF-17 (operating independently) in such scenario then this statement is fairly reasonable. But if you think along the lines of network centric way of war, you'll get your answer.
...I hope this discussion does not escalate to same IAF vs PAF.
