Well,we're not sure on the Pakistani FC-1's avionics fit.They have been actively looking at Italian & French systems & the radar system is likely to be the Italian Grifo S-7.Besides,if China plans to export this fighter to others,European avionics fits are a certainity esp as the EU will soon lift it's arms ban.
well it would be difficult for them to integrate italian ,french and other european systems into a chinese aircraft.COst is another factor.We'll probably wait and see what they do but what i feel is that this aircraft is being purchase by pakis for the foll. reasons:-
1]BVR capability
2]No other option available hence china as the last option to buy aircraft
3]Really REally cheap
J-10 will be a better aircraft than JF-17.
JF-17 was primarily built by the chinese for export to third world countries like pak,bangladesh etc.
And i wouldn't worry much abt chinese made stuff.Not reliable at all!!!
