Chinese have made remarkable progress in avionics and other military tech in the last ten years or so. One thing to note is the PAF never lowered their requirements but Chinese still fulfilled them. Thia was confirmed by jf-17's former project director AVM Shahid Latif. The huge R&D budgets allocated on yearly basis in China are more than any country in the world as of now. The history remind us that french company Sagem offered a glass cockpit for jf-17 back in 2004 with appropriate avionics package but PAF was reluctant to go for it because of price. Here, Chinese friends came up with an offer that PAF could not refuse. The offer was not only for high quality avionics made in China along with glass cockpit, but also with an advanced, multimode pulse doppler radar. This was the reason why Grifo s7 and sagem avionics package was not chosen in the first place.
The key part is that the requirements were NEVER lowered but Chinese kept their innovation style and incorporated a unified, advanced modular mission computer, robust multimode radar compatible with most western and all Chinese/Pakistani weapons, high performing EW equipment (i gave the article in JF-17 thread) and self protection systems and a mystery system i.e. focus interference system.
When i asked my contact about this "focus interference system", he gave me a meaningful smile. After that, i am sure that this fighter has a lot to surprise the enemy. Now, about the current french avionic offer, it is clear that PAF wanted top of the line stuff from french and italians, if they fail to do so, we always have our own brain pool coupled with Chinese Friends. But trust me guys, we will never know this stuff on internet forums!!
