China’s homegrown C919 aircraft lands in Xizang for first time

China's domestically developed single-aisle aircraft, the C919, completed a flight from southwest China's Sichuan Province to neighboring Xizang Autonomous Region on Thursday, marking the aircraft's first landing in Xizang.

The C919 will undergo research and development test flights to assess key systems for high-altitude operations, including environmental control, avionics, and power units. Additionally, systems like environmental control, brakes, and engines must operate at a higher level of performance and reliability,” said assistant chief engineer of the C919.
