Rewatching all the footage, I only found two numbers.

03100 for KJ-600:

05100 for J-35:

  • Didn't see 32. Maybe it is in other footage I didn't check.
  • What is the unit of measurement for these numbers, pounds?? Or are they simply codes?

No idea. Am honestly perplexed.

But I am going to venture a guess based on what i saw from all the clips but then again, the clips are spliced together and maybe they are testing / trialing different methods

First for context (from US carrier)

In this video of weight board operator onboard the US carrier, he shows the weight to the pilot, adjusts some numbers (presumably the weight) and runs to the shooter to show the numbers

Above quoted screenshots for J35:
- #3505 & #3506 J35 pilots were shown "-13" on the white panel on the display
- The weight operator shows his panel number 05100 to the shooter
- Note that this board has some wire sticking out which I assume it is wireless comms

In this screenshot for KJ-600:
- "0" was shown to the KJ-600 pilots; it actually reads "human input: 0 deg"

What I guess is this:
- The "-13" is perhaps a weight / input measure; perhaps it is indicating it is -13 tons(?) below the max limit of the catapult?
- The "05100" might be the ID for the weight board (that thing carried by the weight operator) to ID the weight being transmitted wirelessly to the shooter
- Weight confirmation is being transmitted wirelessly to the shooter vs having the shooter to physically sight and record down the weight and adjust the strength of the catapult

That said, I can't explain "human input: 0 deg" for the KJ-600 or the differences in the display between the one used for KJ600 and J35 launch....maybe "human input: 0 deg" means zero input ie to be shot at max load of the catapult
I think I found out where the 32 came from, it's in few frames before you '人工 0°'.

I think this explains what Shilao and Yankee referred to as the "three-digit display" in Chahuahui. They likely saw a a close-up screenshot by someone else and mistook it for J-35 data (when it was actually KJ-600 data).
Plus, the 弹射 guy was actually showing the pilot the other side display panel '人工 0°'.

Still, we saw the display showing [?][3]0 during a J-35 launch.

Don't forget about L-10/15. Those will also likely be on the Fujian.

Naval variant has two vertical slabs I think. According to Yankeesama it wasn’t so much a decision to improve aerodynamics or stealth as an attempt by Hongdu to “stay relevant” in the aircraft design department since they’ve been focusing on munition too much. Lately Shenyang and Chengdu have made the leap to fifth and sixth gen while Hongdu have stagnated relatively speaking. Twin vertical slabs on L-15 is an economical way to train young aircraft designers and keep some of the RnD capabilities.

Hongdu AC should be more proactive and seriously join the UAV race and compete with other more notable Chinese aircraft design institutes/companies in the diverse fields of UAVs, instead of just sticking with jet trainers and helping Shenyang AC with the production of GJ-11/21.

Same goes for Guizhou AC. Neither of them should ever be content with serving as mere sidekicks of Chengdu and Shenyang ACs.
