This article conclusively answers the seeming conundrum of J-20 pilots stating that their aircraft is easy to fly but hard to master. Like the J-10C, the J-20 is easy to handle/maneuver but since the plane generates so much information, mastering how to best operate the plane in combat situation is difficult. Kudos to Pakistanis pilots for mastering such a bird in such a short period of time.
One other interesting tidbit is the claim that J-10C is semi-stealth. This is inline with leaked information from the Zhurihe Parade a couple of years back where ground radar operators were specifically warned that J-10C (clean) and J-20 (even with lunesburg lens) are difficult to track and require multiple systems covering all the angles for safety purposes. J-16/J-11B do not have this issue.
Keep in mind that J-10C is considered by US military to be almost LO, but that also has to be put in the context where China has a whole variety of EW assets flying around. PAF can achieve similar level of LO only if it buys some EW aircraft from China.
I see that as more important than more AWACS.
I'd be curious to hear from PAF side on whether their F-16s can even pick up J-10C from more than 30 to 40 km out.
