Core Viewpoint - The implementation of the airspace structure adjustment in the Chengdu-Chongqing region is a significant development aimed at enhancing the efficiency and safety of civil aviation operations in China [1][2]. Group 1: Implementation Details - The airspace structure adjustment officially took effect on June 12, with the National Flight Plan Processing Center in Shanghai providing full support for the transition [1]. - The flight plan is a fundamental piece of information for the air traffic control system, and the center had prioritized this adjustment in its annual work plan established earlier in the year [1]. - Prior to the adjustment, the center conducted a thorough review of 83 pairs of conventional routes that would switch to temporary routes and identified 51 flight routes without corresponding temporary routes [1]. Group 2: Risk Management and Preparations - In light of the rainy season, the flight plan center conducted risk assessments to ensure that relevant preventive measures were fully implemented during the operational procedures [2]. - On June 11, the day before the adjustment, Typhoon "Butterfly" began to affect civil aviation operations, necessitating changes to some international flights related to the adjustment [2]. - The center developed various response strategies based on the latest weather conditions and flight delays, ensuring smooth data transition and operational procedures [2]. Group 3: Future Outlook - Following the implementation of the airspace structure adjustment, the flight plan center will accumulate operational experience and continue to provide high-quality flight plan data to support safe and smooth operations [2].

中新社重庆6月12日电 (张旭)重庆市交通运输委员会12日发布消息称，当日零时，随着《成渝及周边地 区空域结构调整方案》实施，重庆空域正式开启"扩容"模式，主干航路由"两横两纵"变为"六横三纵"， 进离场航线结构由"三进四出"增加为"六进七出"。 这是重庆江北国际机场开航以来最大规模空域结构调整，涉及新辟及调整航路航线39条，调整班机航线 走向126条，优化调整15个民航运输机场相关进离场程序。 据介绍，此次空域结构调整，极大优化了重庆地区的航路航线布局，将高效释放重庆江北国际机场"3座 航站楼+1座卫星厅+4条跑道"的地面运行效能，为推动重庆国际航空枢纽建设和成渝地区双城经济圈建 设提供强有力支撑。(完) （文章来源：中国新闻网） 调整后，重庆江北国际机场空域资源配置得到进一步优化，西侧空域由仅1条进场"三边"(飞机在降落过 程中需要遵循的特定航线路径)增加为"两进一出"的3条"三边"，有效缓解进场分流压力，缩短飞行航 程。 同时，东西侧空域可用水平范围扩展至30公里至40公里，大幅缩小其他空域用户穿越通道范围，进一步 打通重庆江北国际机场与周边机场的运行堵点。 进离场程序优化方面，调整后，离场程序航程平均 ...
