##中国国产支线客机ARJ21开启“环青藏高原”演示飞行，剑指高高原航线市场
**中新网北京8月21日电 (记者 孙自法)** 记者从中国商用飞机有限责任公司(中国商飞)获悉，中国商飞一架ARJ21飞机当天从四川成都双流国际机场起飞，经过50分钟的飞行，顺利抵达海拔逾3500米的四川阿坝红原机场，标志着为期一个多月的国产支线客机ARJ21“环青藏高原”演示飞行正式开启。
此次“环青藏高原”演示飞行是ARJ21飞机继新疆喀什往返塔什库尔干航线成功运营后，又一次针对高高原机场和航线进行的适应性验证。ARJ21飞机将以四川成都、青海西宁和西藏拉萨为运行基地，飞抵西藏、四川、青海和甘肃的多座高高原机场，全面测试其在高海拔地区运行的适应性、机场地面服务设备的适配性和特殊飞行程序的适用性。
据了解，中国共有25座高高原机场，占全球高高原机场(跑道长度2000米以上)总数量的50%以上。高原地区空气稀薄、地形复杂、气象多变，对飞机性能、机组人员资质和运行保障能力要求极高。ARJ21飞机在设计之初就考虑到中国西部地区的运行情况，把高原性能作为重要指标，并在云南、新疆等地开展演示飞行。此次“环青藏高原”演示飞行将进一步验证ARJ21飞机的高原运行性能，为国产商用飞机开通更多高高原航线、加快“边疆快线”实施落地奠定基础。
近年来，随着中国经济社会的发展，高原地区民航运输需求逐步增加，对适应高高原机场和航线的飞机的需求也日益增加。ARJ21飞机作为中国首次按照国际民航规章自行研制、具有自主知识产权的中短程新型涡扇支线客机，其成功运营将为中国民航市场提供更多选择，并助力中国民航产业发展。
中国商飞表示，此次“环青藏高原”演示飞行将为ARJ21飞机开拓高高原航线市场提供宝贵经验，为国产商用飞机在高海拔地区实现更大发展奠定坚实基础。

## China’s domestically produced regional jet ARJ21 embarks on a”circling the Qinghai-Tibet Plateau” demonstration flight, targeting the high-altitude route market.
**Beijing, August 21 (Xinhua)**- A Commercial Aircraft Corporation of China (COMAC) ARJ21 aircraft took off from Chengdu Shuangliu International Airport in Sichuan Province today, and after a 50-minute flight, successfully landed at Hongyuan Airport in AbaPrefecture, Sichuan, which is located at an altitude of over 3,500 meters. This marks the official launch of the month-long “circling the Qinghai-Tibet Plateau” demonstration flight of the domestically produced ARJ21 regional jet.
This “circling the Qinghai-Tibet Plateau” demonstration flight is the ARJ21’s second adaptation verification for high-altitude airports and routes, following the successful operation of the Kashgar-Tashkurgan route in Xinjiang. The ARJ21 will use Chengdu,Xining in Qinghai, and Lhasa in Tibet as operating bases, flying to multiple high-altitude airports in Tibet, Sichuan, Qinghai, and Gansu, comprehensively testing its adaptability to high-altitude operations, the compatibility of airport ground service equipment, and the applicability of special flight procedures.
It is understoodthat China has a total of 25 high-altitude airports, accounting for over 50% of the total number of high-altitude airports (with a runway length of over 2,000 meters) globally. High-altitude regions have thin air, complex terrain, and variable weather, posing extremelyhigh demands on aircraft performance, crew qualifications, and operational support capabilities. The ARJ21 was designed with the operating conditions of western China in mind, making high-altitude performance a key indicator, and has conducted demonstration flights in Yunnan, Xinjiang, and other regions. This “circling the Qinghai-Tibet Plateau” demonstration flight will further verify the ARJ21’s high-altitude operational performance, laying the foundation for the opening of more high-altitude routes for domestic commercial aircraft and accelerating the implementation of the “Frontier Express.”
In recent years, with the development of China’s economy and society, the demand forcivil aviation transportation in high-altitude regions has gradually increased, leading to a growing need for aircraft suitable for high-altitude airports and routes. As China’s first independently developed and manufactured medium-short-range new turbofan regional jet, compliant with international civil aviation regulations and possessing independent intellectual property rights, the successful operationof the ARJ21 will provide more choices for the Chinese civil aviation market and contribute to the development of China’s civil aviation industry.
COMAC stated that this “circling the Qinghai-Tibet Plateau” demonstration flight will provide valuable experience for the ARJ21 in opening up the high-altituderoute market, laying a solid foundation for the greater development of domestically produced commercial aircraft in high-altitude regions.
