Special interview with a J-20 pilot who participated in the National Day flyby starting at 13:50.

Key takeaways:

1. The most difficult part of the flyby was maintaining aircraft position within the formation.
2. The J-20 is highly maneuverable and uses a side stick controller, which is highly receptive to user input. This is actually a disadvantage for formation flying.
3. They spent three months practicing for the 3 second flyby for National Day.
4. Since the J-20 uses stealth coating (which is very expensive), they didn't draw a reference line on the aircraft body for the purpose of the flyby.
5. Standards for selecting J-20 pilots are very strict and they must be able to withstand +9g/-3g.

So here we have a seven ship formation of J-20, this is 1/2 of the known serials? in the air for the 70th. We should expect at some point to once again hear and see "primer birds" rolling out of Chengdu for first flights/test flights? anxiously waiting.....

so while many of us certainly miss the "wall climbers" daily reports and pix of the "old days"? we have now seen many more pictures and videos including main bay and side bay weapons displays at Zhuhai 2018. Photo's of instrument panels and cockpits, including detail of the side stick controller, etc.

No doubt a beautiful sight and sound to have witnessed this large formation flyover!

I believe every electronic fly by wire system on a modern fighter since the F-16 has employed a side stick controller, which is indeed far more sensitive to control input than the F-15s central floor mounted joy stick. While the F-15s boosted stick does provide more "real feel", they do try to build some feel into the side stick controller.

immediately aft of the side stick is a cushioned arm rest to fully support your forearm, hopefully helping you to avoid "over controlling".

These types of informational interviews provide us with the most accurate characterization of the J-20 yet! dispelling the myth that the J-20 was an interceptor only bird, as well as the 15T myth that the J-20 wasn't built up to the full 9G heavy fighter standard.

His very specific +9G, -3G standard for pilot candidates should lay both of those myths to rest, at least here on SDF.

I’ll bite. The Su-27 is 16 tons and can pull 9Gs. The only myth here is the sophistry that you need to weigh as much an F-22 to handle that many Gs. Clearly when we had this debate you weren’t reading anything I said. Next time I’d appreciate it if you don’t do flippant snipes with distorted versions of people’s arguments.

actually no.
F16 employs it yes as do F22, F35, Rafale.
However Hornet, Super Hornet, Gripen, Typhoon, Flanker all versions, Fulcrum upgraded versions SU57 use a fly by wire system with a traditional center stick.
Chinese fighters would be divided based on if derivative of Flanker or indigenous design. The Chinese indigenous J10 and J20 are stated as side stick. This could be unique to there maker or a requirement for the PLAAF new aircraft.

There is no reason why center stick controllers would have to be be less sensitive to user input then side stick controller. The first side stick controllers appeared more sensitive because If was fixed with no movement, and sensed the force the pilot applied, where as traditional center column required significant amplitude of movement. But center column controller can also be made fixed and sentive to force applied instead of amplitude of movement.

Apparently the Soviets considered and experimented with rigid force sensitive side stick for both Su-27 and MiG-29, but rejected them and used tradition center column based on pilot feedback.
