Well, to complicate things, for an aircraft turning speed is also dependent on lift and the static stability, plus we don't know what the mass of this aircraft is. He was asking about length so I just assumed ceteris paribus.latenlazy wrote:
Length gives you a longer momentum arm so it's easier to turn your nose
For aircraft of the same shape but different size the larger aircraft has a larger moment of mass and so it is slower in following the control surface deflections. It is less easy to turn your nose.
^^^^ It's the parachute housing
Flying with parachute housing open? That's kinda odd isn't it?

The wheels on the J-20 and Su-27 are about the same size. Same thing for length of cockpit, size of pilots' heads, size of pilot helmets, and engine size.

You guys don't know what you're doing.
You are quite right, I examine the picture pixel by pixel - everything seems to line up almost perfectly, EXCEPT the pilot's head - either Chinese pilot's head is enormous (its about 130% larger) or the J-20 is smaller.
For some reason, J-20 looks closer to the camera hence the pilot looks larger. If you scale it down slightly, I think it might even be smaller than F-22 or PAK FA.
Also Su-27UB is 21.9 m long, from tip of the nose to the end of the boom, even measuring against that J-20 is shorter by quite a bit.
I don't see anything too strange... Or is this pic psed?
