On September 11, 2024, as night fell, Hangzhou Xiaoshan International Airport in Zhejiang Province welcomed a historic moment - the first domestically produced large passenger aircraft C919 officially debuted as a commercial passenger flight of Air China, marking a new stage of development for China's aviation industry. This aircraft, carrying a sense of national pride, aircraft number B-919X, slowly glides to the runway under dazzling lights, preparing to embark on its glorious journey as a pioneer in commercial operations.

The "Hangzhou Xiaoshan Beijing Capital" boutique express line operated by C919 this time is not only an economic artery connecting two important cities in China, but also an important window to showcase the strength and innovation capability of China's aviation manufacturing industry. The Air China C919 adopts the industry-leading extended range design, which endows it with greater maximum takeoff weight and enhanced engine thrust. This not only enhances its range capability, but also ensures safe flight under various complex weather conditions, greatly expanding its market adaptability and operational flexibility.

The addition of C919 not only enriches the fleet structure of Air China, but also brings passengers a more comfortable and efficient travel experience. As a representative of domestically produced large aircraft, the C919 has reached international advanced levels in cabin design, noise control, fuel efficiency, and other aspects, aiming to provide passengers with spacious and comfortable seating space, smoother flight experience, and lower carbon emissions, reflecting Air China's active practice of sustainable development concept.

In addition, the normalized operation of C919 has profound significance for promoting the improvement and development of China's aviation industry chain. From design and development to production and manufacturing, to airworthiness certification and commercial operation, the success of C919 embodies the wisdom and sweat of countless researchers and industrial workers, and is a concentrated demonstration of China's aviation industry's independent innovation capability. With the gradual promotion and application of C919 globally, it will effectively promote China's aviation manufacturing industry to move towards the high-end of the industry chain, further enhancing China's voice and influence in the global aviation market.
