"After seven days and 16 flights of plateau scientific research verification flights, the ARJ21-700 aircraft independently developed by China completed the test flight certification of the airport at the altitude of 2184 meters for the first time, marking that China's own ARJ21-700 aircraft has been The ability to fly safely in the highland environment,†said Wang Xiaoxi, head of the comprehensive business department of the Qinghai Branch of the Air Traffic Management Bureau of the Northwest Civil Aviation Administration of China in an interview with the China News Service on the 4th.
The new ARJ21 regional aircraft is the first mid-range and short-range turboprop regional aircraft independently developed by China in accordance with international civil aviation regulations and has independent intellectual property rights. It is seated between 78 and 90 seats, with a range of 2225 km to 3700 km. It is mainly used to meet the requirements from the central city. The use of radial routes in small and medium-sized cities in the surrounding area.
Wang Xiaolu said that only two ARJ21-700 aircraft are currently operating on the Shanghai-Chengdu route, but the design specifications of the ARJ21-700 aircraft are also suitable for the operation requirements of the take-off and landing of high altitude airports in western China and complex route obstacles. In China's Shaanxi, Gansu, Ningxia and Qinghai regions, most of the airports are high altitude airports with an altitude of more than 1,500 meters, especially in Qinghai Province. Except for Xining Airport, other airports have been constructed and are planned to exceed 2,438 meters above sea level. Both belong to the plateau airport.
As we all know, in the plateau environment, the performance of aircraft engines will be significantly weakened, the thrust generated by the engine will be significantly reduced, and the aircraft's flight performance and the status of various systems will change accordingly, which raises the requirements for the aircraft's safety level and operating capability.
"To this end, after a period of seven days and 16 sorties of plateau scientific research verification flights, the ARJ21-700 aircraft independently developed by China completed the test flight verification for the Gaoyuan Airport at the altitude of 2184 meters for the first time, fully verifying that the aircraft was upgraded after the operating system. , has the ability to fly safely in the highland environment." Wang Xiaojun said that in the future ARJ21-700 aircraft will be used in the mission to fly the airports in Qinghai Province.
Wang Xiaoyun said that the ARJ21 aircraft was successfully tested at Xining Airport for the first time, not only laying the foundation for the rapid development of Qinghai’s highland civil aviation industry, but also accelerating the development of the civil aviation transportation industry in the central and western regions of China and facilitating the travel of passengers in the central and western regions.
