That’s called differential thrust. We’ve seen this happen numerous times both in the air and prior to takeoff.
J-20 5th Gen Fighter Thread VIII
- Thread starter Blitzo
- Start date
I am aware, although it just doesn't seem all that practical to the best of my knowledge, especially since the moment arm would be quite small on J-20 compared to fighters with wider spaced engines/shorter fuselages. Assuming WS-15 spools fast, I don't know why differential thrust would be used especially given rudders seem like a much superior option even at low airspeed, unless its digital. What am I missing here?
Also hide the engine nozzles from the sides. Beside small updates, I dont see further big evolution on the J-20 platform with the sixth generation fighters coming along.

Afaik pilots do actively use differential thrust in crosswind conditions during landing. See:
Seems reasonable then. Next step would be to find the J-20 doing it. I'll see if I find anything.
Where are my apologies???
I won’t be satisfied until we see in service J-20A with WS-15. Tired of watching yellow primer J-20A with WS-15.
I have some good news and some bad news.
First the good news: You're already seeing in-service J-20As with WS-15s.
Now the bad news: The new PLAAF color is yellow.

if this has already been posted or asked feel free to delete, i couldnt find it within 50ish pages 
seems like there are differences between the intakes on the j20. adding a diverter to a diverterless supersonic intake? the bump itself seems to have also changed shape. any ideas?
