China's domestically developed single-aisle aircraft, the C919, landed at Lhasa, Xizang autonomous region for the first time on Thursday, as the model verifies its adaptability to ultra high-altitude airports and routes.The C919 jet, operated by its developer Commercial Aircraft Corp of China, or COMAC, departed from Chengdu Shuangliu International Airport (CTU) on Thursday morning and arrived at Lhasa Gonggar International Airport (LXA) after about two hours of flight.
on september 19, a c919 aircraft of commercial aircraft corporation of china took off from chengdu shuangliu international airport in sichuan and landed smoothly at gonggar international airport in lhasa, tibet, after a 2-hour and 8-minute flight. this was the first time that a c919 aircraft arrived in lhasa.
Located in the Yarlung Zangbo River valley at an altitude of 3,569 meters, the Lhasa airport is surrounded by mountains. The meteorological environment is complex and poses a number of aeronautical challenges for aircraft and crew.
lhasa gonggar international airport is located in the yarlung zangbo river valley, at an altitude of 3,569 meters. it is surrounded by numerous mountains and the weather environment is complex and changeable, which places high demands on the aircraft's plateau operating performance.
As such, the C919 plane will carry out research and development test flights of key systems for high-altitude operations, including environmental-control system, avionics and power units, as the company prepares the plane to meet the operational needs of ultra high-altitude routes and the R&D of the plateau variant in the future, COMAC said.
after arriving in lhasa, the c919 aircraft will carry out research and development test flights of key high-altitude operation systems such as environmental control, avionics, and power units, as well as high-altitude airport adaptability inspections, laying the foundation for subsequent meeting high-altitude route operation needs and high-altitude prototype research and development.
So far, the C919, comparable with the narrow-body Airbus A320 and Boeing 737 series, has netted more than 1,000 orders from home and abroad.

Earlier this year, Tibet Airlines, a regional carrier based in Lhasa, signed a deal with COMAC for 40 C919 aircraft of the plateau variant which is designed to meet the complex transportation requirements of high-altitude regions by shortening the fuselage and featuring high-altitude modifications.
earlier this year, reporters learned from comac that on the opening day of the singapore air show, tibet airlines signed an order with comac for 40 c919 high-altitude aircraft and 10 arj21 high-altitude aircraft. henan aviation investment and comac signed an order for 6 arj21 derivative aircraft, including arj21 fire extinguishers, arj21 medical aircraft and arj21 emergency rescue command aircraft.
"China has the world's largest demand for high-altitude aircraft operations," said Lin Zhijie, a civil aviation industry analyst. "The plateau variant of the C919 is of great significance for meeting the travel demand of passengers in high-altitude regions of China."

Meanwhile, China's first home developed regional passenger jet, the ARJ21, is close to finishing its month-long ultra high-altitude demonstration flights around the Qinghai-Xizang Plateau that will fully assess the adaptability of the model for ultra high-altitude airports and routes. The C919 and the ARJ21 gathered in Lhasa on Thursday.
at the same time, china's first independently developed regional passenger aircraft arj21 will be based in chengdu, sichuan, xining, qinghai and lhasa, tibet, and fly to many high-altitude airports in tibet, sichuan, qinghai and gansu, fully verifying the adaptability of the arj21 aircraft to high-altitude airports and high-altitude routes, the adaptability of airport ground service equipment and the applicability of special flight procedures, and better and more comprehensively meet the operational requirements of high-altitude areas. the c919 aircraft and the domestically produced regional passenger aircraft arj21, which is undergoing a demonstration flight, meet on the qinghai-tibet plateau.
Since Aug 21, the ARJ21 aircraft started its demonstration flights around the plateau, using Chengdu, Sichuan province; Xining, Qinghai province; and Lhasa as operational bases. So far, the ARJ21 plane has completed flight tests on 25 routes for a combined total of 62 flight hours, covering 11 ultra high-altitude airports in China.
since august 21 this year, the arj21 aircraft has carried out the "around the qinghai-tibet plateau" demonstration flight with chengdu, sichuan, xining, qinghai and lhasa, tibet as its operating bases. so far, it has completed 25 routes, 55 flight segments, and 62 hours of flight missions, covering 11 high-altitude airports.
In particular, the jet has flown to the world's highest civil airport four times, and fully verified its adaptability to ultra high-altitude operations. Located 4,411 meters above sea level, Daocheng Yading Airport (DCY) in Sichuan province is not only the highest civil airport in China, but also the world.
it has also flown to daocheng yading airport, the world's highest civil airport, four times, fully verifying the adaptability of the arj21 aircraft to high-altitude operations.
Airports located at an altitude of 2,438 meters or above are regarded as ultra high-altitude airports, and China has 25 such airports, accounting for more than half of such airports globally with a runway length of over 2,000 meters each, according to the Civil Aviation Administration of China.
according to the civil aviation administration of china, airports with an altitude of 2,438 meters or above are high-plateau airports. currently, there are 25 high-plateau airports in china, accounting for more than 50% of the total number of high-plateau airports (runway length of more than 2,000 meters) in the world.
High-altitude regions face conditions such as sparse oxygen supply, complex terrain and ever-changing weather conditions. The requirements for aircraft performance, crew qualifications and operational support capabilities are extremely high, the CAAC said.
