China's COMAC has completed the maiden test flight of its new C919 high-altitude (plateau) variant in Shanghai. On July 29, 2026, the prototype, registered as B-002U (C919-600), took off from Shanghai Pudong International Airport and performed all scheduled maneuvers during a flight lasting one hour and 59 minutes. Jointly developed by COMAC and Tibet Airlines, this high-altitude variant features a shortened fuselage that is approximately six frames shorter than the standard version. It is designed to accommodate between 140 and 160 passengers and operates in high-altitude regions, which Chinese regulations define as airports at elevations of 2,438 meters or higher.
