Ask for advice; Ternary TVC, such as X3 1, has good liquidity. Why does American F22A use binary TVC? Although Indian Su 30 is ternary, why is it abused by F 15C?

What's the use of being able to move horizontally outside the yaw axis? This is nothing more than complicating flight control, increasing production and maintenance problems and weight. Not to mention the F-22 has to take care of stealth. This is only necessary when pneumatic control is really not needed.

TVC is TVC, and thrust is thrust. If the thrust is not enough, you will lose speed if you want to turn with a small radius. TVC once again trades thrust for pitching moment, and an aircraft with serious weight problems, Su Like -30MKI, will have problems. The thrust of F- 15C is well known. Su -30MKI lost when it started to beat around the bush with F- 15C. Having JHMCS and AIM-9X is also an absolute advantage in weapons (but BFM should not use this), and it is not surprising to be completely abused.
