A good internet "Leak" or BS for interested readers to scratch the head?
Why ?? Can You please explain this date ???
They were running a voice control demonstration for TV, I don't think they'd be allowed to show the actual UI on the J-20. Besides, newer J-11/15/16 variants may use the same display. Previous generations of HUD and display modules were often shared among different Chinese fighters.
Rumours from a BBS member called "bowman" claims that the pair of J-20s spotted at Dingxin took part in Red Arrow, facing off against J-10s, J-11s, and Su-30s. The result was utter annihilation of the 3rd-gen fighters; 10 - 0 in favour of the J-20s. The 3rd-gens didn't even see the enemy before being destroyed and neither did ground control with their land-based radar.
Besides stealth technology, 'bowman' also claimed that EW measures made no impact. This would suggest that advanced signals management and LPIR technology are employed in the J-20's avionics.
related high res picture of it:
I think the video at 54 sec says that J-20 uses this new display (??) which is 24 inch x 9 inch??
Also the voice control mechanism is really cool.
and older picture from about a year ago of the same display -- back then we had no video of the display in use, but with this latest video it does tell us a lot more about its functionality
