Su-57 ZhuHai Airshow

[RussianTroll]

It’s a thrust to weight demonstration more or less. At normal takeoff weight the Su-57 has a thrust to weight ratio of 1.09, and 0.97 at loaded weight. For an Airshow, with minimum fuel it’s probably closer to 1.11. That allows for them to use thrust to “hold” the aircraft in the vertical position like you saw in the video. Most of these maneuvers aren’t really useful in combat, but look great at Airshows.

It is also necessary to take into account that the air show exhibition in China's Zhuhai presents an export version of the Su-57. That is, many systems are seriously cut down, and the aircraft itself is adapted only to the requirements of foreign customers, which seriously excludes the latest technologies used in the Russian armed forces.
