1) The entire airframe.Is there anything pure Indian in this plane? Except for brain farts?
It wasn't designed and tested in Chengdu, like "Pakistan's" JF-17.
2) The EW suite and the jammers:
They were both completely homegrown, a feat which Pak cannot hope to do in the near future.
3) The entire FBW system for the aircraft.
Again, something that Pak just cannot hope to make.
4) Composite materials
A very cutting edge technology that few countries have the brains to research and develop.
5) Fully glass cockpit.
Forget glass cockpit, Pakistan has not designed even an analog one.
6) Avionics - dedicated mission computers, display processors, video switching units, digital map generators, each with separate modules & processor units, all as separate boxed LRUs; an innovative open architecture computer to handle all these.
Want more? There is a lot more, but this should be enough for starters. This is just what I could name off the top of my head. The LCA Tejas is more Indian than the Gripen is Swedish. The Su-30MKI is more Indian than the JF-17 is Pakistani. Food for thought.
It is risible that a country that cannot make a motorbike should try to beliittle India's accomplishments, no matter how modest they may be in comparison to major aerospace powers.
