China’s first high-altitude variant of the C919 narrowbody jet has completed its maiden test flight at Shanghai Pudong International Airport, reports the South China Morning Post. The move marks a step forward in the home-grown aircraft’s challenge to Boeing and Airbus.
Derived from the standard C919 platform, the specialized variant features a shortened fuselage and enhanced systems engineered for operations in high-altitude regions. The plane will undergo comprehensive airworthiness certification and environmental adaptability trials across various high-plateau airports before entering commercial service.
Its manufacturer, Commercial Aircraft Corporation of China (Comac), signed a framework agreement in 2023 with Tibet Airlines to develop the high-altitude model. A year later it locked in a deal with the airline for 40 C919 high-altitude variants.
