The flight control system uses mechanical links to power surfaces and computer driven tailoring for carefree handling in symmetric maneuvers. In rolling flight, there is an angle-of-attack limit of 26° with aileron authority progressively phased out, but in combat the pilot can physically override pitch and G-limiter. A typical sustained turn radius (at sea level) of 225 meters (738 feet) at 450 kph (246 kts) and 350 meters (1148 feet) at 800 kph (437 kts) can be achieved. Horizontal accelerations at Mach 0.85 of 11 m/sec2 (36 ft/sec2) at sea level and 6.5 m/sec2 (21.3 ft/sec2) at 6,000 meters (20,000 feet).
Причём речь здесь идёт об установившейся перегрузке! И максимально допустимый угол атаки больше 26 градусов...
