中国日报11月17日电 (记者 赵磊) 记者从中国航空工业集团有限公司获悉，国产大型民用直升机AC313A近日顺利空转抵达景德镇吕蒙机场，圆满完成首次高原试飞工作。
The first altitude test flight of the AC313A set off on September 10, and was conducted at HuangGuoshu Airport at an altitude of 1,600 meters, Lugu Lake Airport at an altitude of 3,300 meters, and Daocheng Yading Airport at an altitude of 4,400 meters. In accordance with the principle of "easy first and difficult later, low first and high first, light first and heavy", it is gradually implemented to check the plateau flight performance and flight quality of the helicopter, as well as the adaptability of the engine, auxiliary power device, starting and control system, etc., and carry out technical research for the altitude test flight of the model airworthiness certification.
AC313A首次高原试飞于9月10日启程，先后在海拔1600米的黄果树机场、海拔3300米的泸沽湖机场、海拔4400米的稻城亚丁机场进行。按照先易后难、先低后高、先轻后重的原则逐步实施，检查直升机的高原飞行性能和飞行品质，以及发动机、辅助动力装置、起动及控制系统的高原适应性等，为型号适航取证高原试飞进行技术摸底。
