Open Source photos have finally appeared of the Chinese ski jump test facility, and it looks like they have at least one FLANKER test article. The one ground-level picture had appeared a few months back, but when I asked xinhui and others for the location, the only answer I could get was the Shenyang test facility. That was not correct. Now for the first time that I have seen, someone has gotten a hold of recent overhead imagery of the Xian-Yanliang test facility, which is where this ramp was built within the last couple years.
Building it there seems an unusual choice, given its altitude of over 1500ft above sea level. Maybe they have good weather for testing there, with frequent sustained high winds that might better simulate wind over the deck during air operations?
Here are some totally unrelated photos that were taken last week.
