In a significant achievement for civil aviation, China’s independently-developed AC311A helicopter has successfully passed a demanding sling-load flight test in Lhasa, located in the southwestern Xizang Autonomous Region. The test, conducted by the Aviation Industry Corporation of China (AVIC), showcased the helicopter’s impressive capabilities in high-altitude conditions.
The AC311A, a six-seat, two-tonne light single-engine civil helicopter, undertook the sling-load operation by lifting and slinging freight weighing 325 kilograms at an airport situated at an altitude of 3,680 meters in Lhasa. Despite the challenging plateau environment, the helicopter performed flawlessly, executing a series of maneuvers including climbing, turning, level flight, and gliding, before landing safely.
AVIC highlighted the helicopter’s excellent flight controllability and stability throughout the entire process, underscoring its suitability for operations in high-altitude regions. The AC311A boasts a maximum take-off weight of 2,250 kilograms, a cruising speed of 240 kilometers per hour, a maximum range of 630 kilometers, and can operate at service ceilings up to 6,000 meters.
This successful test not only demonstrates the AC311A's robust performance but also marks a significant milestone in China’s ongoing efforts to advance its civil aviation technology. As the demand for versatile and reliable helicopters grows globally, the AC311A is poised to make a substantial impact in both domestic and international markets.
