haha, I just finished watching it.
And the JAS-39 has a American engine, Is it not a 4th gen?
What thoery a "early 4th gen fighter" is? Is LCA a late 4th-gen? Are F16 F15 early or late? you confused me.
Just tell me simply, which one or part on or inside the JF-17 can not match the admitted standard of 4th-gen fighter?

BEIJING—Images and witness accounts posted online Tuesday appeared to show that China's stealth fighter prototype had made its first test flight, even as Robert Gates, the U.S. Defense Secretary who has downplayed China's stealth aircraft capability, was meeting Chinese civilian leaders in Beijing.
Over at CDF, did we spot the J-10B equipped with FWS-10A? I have never seen a production J-10A with WS-10A or FWS-10A. The B variant is either an export model or a prototype; it was thought that it might have been a testbed for J-20 systems, but we've seen it with a radome designed for PESA or AESA.
As far as the JF-17 goes; fourth generation by the American definition is based on FBW and relaxed stability. The JF-17 has relaxed stability alongside FBW in the pitch axis, but is manually controlled on the yaw and roll axis. By this defintion, the JF-17 is either a 3.5th or 4th generation fighter.
We're expecting the J-20 to be using the WS-10G, which is a heavily-upgraded version of the WS-10 with 140-150Kn output. Weight doesn't necessarily have to scale, the WS-10A is at 132Kn and something around a 7.8 T/W; boosting it just up to current generation American standards would easily put it at 150Kn.
Don't mind me, i'm just going to make a bizzare comparison of 2 very similar photos... (almost confused me of the 2 when I saw it for a second)
Also, given the size of this thing, anyone noticed how LONG the landing gears are?

FBW, Fly by wire flight control system,including analog and digital. JF-17 has half analog and half digital FBW to meet Pakistan's costcontrol, But the FBW including analog and digital are far from the manual contol.
Large pic of J-20 today:

It's actually somewhat disappointing watching it up in the air; with its boxy shape it just reminds one of the idea that someone decided to "stealthify" a J-10 and didn't do a very good job of it. You can't really see the trapezoidal shape of the delta wing, either.
The J-20 does not look stealthy whatsoever from the back- round engine nozzles, no trailing edge angle alignment, no saw tooth edges (although not required with new technices like the F-35 has), etc. The wing area seems small relative to the rest of the aircraft (as compared to the F-22 and T-50). While the aircraft has all moving tails and the canards are large and placed a good distance away from the CG of the aircraft, I doubt these features provide better maneuverability (especially high speed, high altitude) than an aircraft with TV. The high sweep angle on the wings looks like this aircraft is definitely intended to go fast though. This further leads me to speculate that this aircraft is probably optimized for frontal stealth only, high speed dashes, and will likely not be as manueverable as the F-22 and T-50. Until we get more details on the aircrafts systems, I don't see any reason for the west to lose too much sleep. Although, I do hope that this puts things in perspective and reminds the US that there are other threats besides insurgencies and terrorists (that you means you Mr. Gates).
Of course, this is just a prototype as far was we know.

For stealth; roundness is ideal as it greatly reduces the diffraction of incoming waves.
Phoenix10: TVC is supposed to be in the cards for the J-20, but it doesn't look as though the current engine is TVC-capable. That's why I think it's likely to be a WS-10G, not a WS-15; for the latter, TVC is supposed to be installed.
I suspect the plane might not meet the stealth level of the F-35; it's also not likely to have the same level of maneuverability as the PAK-FA. As far as the F-22 goes; well, if you slap on TVC later, 2-D or 3-D, with canards it's likely to beat at least the F-35 in maneuverability.
