Scan the QR code with wechat and share it with friends and circles of friends COMAC official wechat announced on August 1 that the domestic large aircraft C919 completed its certification test flight related reading: recently, domestic large aircraft C919 appeared in many airports across the country. On July 12, C919 made its first flight to Beijing Daxing International Airport; On July 8, C919 conducted functional and reliability test flights at Guilin airport and Beihai airport; At 12:01 on July 7, the domestic large aircraft C919 landed at Wuhan Tianhe Airport; On July 5, C919 took off and landed at Zhengzhou airport in the rain for the first time

frequently appeared behind, C919 was only "one step away" from the airworthiness license delivery - obtaining the aircraft airworthiness certificate from the Civil Aviation Administration of China. According to the plan, C919 will be certified, delivered or realized within the year

what have domestic large aircraft been doing for the first five years

6 test flights were carried out in Yanliang, Nanchang, Dongying and other places for flight test and evidence collection, and tests were carried out in stall, power, performance, stability, flight control, icing, high temperature, high cold and other subjects The C919 airliner is China's first self-developed single channel mainline airliner in accordance with the latest international airworthiness standards. Its main manufacturer is Commercial Aircraft Corporation of China (hereinafter referred to as "COMAC"). On May 5, 2017, the C919 successfully completed its first flight after being offline at the 4th runway of Shanghai Pudong airport

in the five years after the first flight, six C919 test flights were carried out in Yanliang, Nanchang, Dongying, Xilinhot, Turpan, Dunhuang and other places to obtain evidence, and comprehensively carry out the test flights of stall, power, performance, stability, flight control, icing, high temperature, high cold and other subjects

"civil aircraft can only be delivered to users after going through the stages of project approval, design, ground test, flight test and airworthiness certification." Aviation blogger fatiii told reporters that C919 is currently in the airworthiness certification stage, and the design quality, manufacturing process and flight quality of C919 are comprehensively assessed through flight test. "In order to ensure that the aircraft can have sufficient safety and reliability, the airworthiness certification test projects are many, difficult and time-consuming, and hundreds of subjects need to be tested." on May 14, the first C919 large aircraft to be delivered to the first user completed its first flight test. Xinhua News Agency issued taking the Airbus single channel a320neo aircraft as an example, it made its first flight on September 25, 2014, and then conducted a total of 3000 hours of test flight. On January 20, 2016, the first aircraft was delivered to Lufthansa

why does it take only more than a year for the a320neo to fly from the first flight to delivery? "Fatiii" points out that, first of all, the a320neo is an upgraded model based on the mature A320; Secondly, COMAC is the first self-developed trunk airliner, which needs to be explored step by step to ensure safety

compared with the mature aircraft manufacturers Boeing and Airbus, COMAC starts from scratch. In 2008, COMAC was established, marking the official launch of China's large passenger aircraft development project. On January 6, 2009, COMAC officially released the first single channel 150 seat large aircraft with conventional layout, code named "comac919", referred to as "C919". Since then, after years of innovative practice, five international advanced production lines have been built, including final assembly mobile production, central wing, middle fuselage, horizontal tail and full aircraft docking, and more than 100 core key technologies have been overcome. In 2017, C919 finally soared to the skies, marking that China has since become one of the few countries with the ability to develop large passenger aircraft

five years after its first flight, C919 is getting closer and closer to the goal of putting into commercial operation. In January this year, Wu Yongliang, deputy general manager of COMAC, said in an interview that the C919 project is still in the airworthiness certification stage and is expected to be delivered in 2022. For airlines introducing new models, after receiving C919, they need to carry out a series of verification and test flights before they can be officially put into commercial operation

which routes can experience C919 in the future

domestic airlines deeply participated in the design and development process of C919, trained and provided the first crew of C919, accompanied the first flight of C919, and provided suggestions from the perspective of user use and maintenance on May 14, a C919 aircraft numbered b-001j took off from the fourth runway at Shanghai Pudong Airport and landed safely after 3 hours and 2 minutes, marking the successful completion of the first flight test of the first C919 that COMAC is about to deliver to the first user. Before that, the aircraft has completed the fuselage painting of China Eastern Airlines

last March, China Eastern Airlines and COMAC officially signed the purchase contract for the first five C919 aircraft, which will become the first airline in the world to operate large domestic aircraft. Previously, China Eastern Airlines' 123 Airlines began to operate domestic ARJ21 aircraft in 2020

it is understood that China Eastern Airlines has deeply participated in the design and development process of C919 large passenger aircraft, cultivated and provided the first crew of C919, accompanied the first flight of C919, and provided suggestions from the perspective of user use and maintenance

according to the preliminary arrangement, after the introduction of the five C919 aircraft, Shanghai will be the main base, and the routes from Shanghai to Beijing Daxing, Guangzhou, Shenzhen, Chengdu, Xiamen, Wuhan, Qingdao and other routes will be encrypted, so as to improve the market share of China Eastern Airlines in the above markets

China Eastern Airlines said in its annual report released at the end of March this year that it plans to complete the introduction of five C919 aircraft from 2022 to 2023, including three this year and two next year. On the evening of May 10, China Eastern Airlines announced that it plans to raise 15billion yuan to introduce 38 aircraft, including 4 domestic C919 aircraft, 24 domestic ARJ21-700 aircraft, 6 Airbus a350-900 aircraft and 4 Boeing b787-9 aircraft. The announcement also revealed that the unit price of the domestic large aircraft C919 was US $99million, equivalent to about 653million yuan

in addition, Air China, China Southern Airlines, Hainan Airlines, Sichuan Airlines, Xingfu airlines, Hebei airlines, etc. are also interested in ordering. So far, the C919 has received 815 orders from 28 customers

it is understood that COMAC has also submitted an airworthiness application to the European Aviation Safety Agency (EASA) for C919 to prepare for potential export orders, and has been accepted by EASA. As the main examination institution of C919 aircraft, the Shanghai Civil Aviation examination and approval center also revealed that EASA had previously participated in a number of accreditation examinations of C919 aircraft. However, the final assembly production place of C919 is in China, Civil Aviation Administration of China is the main review country of C919 aircraft, and EASA mainly conducts approval review according to the requirements of the European Union. Therefore, first obtaining the China airworthiness certificate (type certificate) is one of the steps for C919 aircraft to obtain EASA airworthiness certificate (type approval certificate) and export

"at present, the main orders of C919 come from domestic customers. Only by doing a solid job in the domestic market can we lay a foundation for opening the international market and obtaining airworthiness certificates in Europe and America." “FATIII”Say

the "14th five year plan" for the development of modern integrated transportation system issued by the State Council points out that China will focus on promoting the demonstration operation of C919 large passenger aircraft and the seriation development of ARJ21 regional passenger aircraft. "In 2022, the large aircraft project will gradually shift from the development stage to the industrialization stage." On February 7 this year, he Dongfeng, chairman of COMAC, said

are there any markets for the C919 after the three airlines bought so many planes

it is estimated that China will receive 9084 passenger planes with 50 seats or more in the next 20 years. Experts said that the three major airlines in China bought aircraft from Airbus with great efforts, which would not affect the sales of C919

recently, the three major airlines in China have successively announced that they have ordered 292 Airbus a320neo series aircraft from Airbus. These aircraft will be delivered in batches from 2023 to 2027. As a 150 seat single aisle aircraft, C919 targets Boeing B737 and Airbus A320, with a range of about 4075-5555 kilometers

why did the three major airlines make a big purchase of aircraft? As a competitive model, is there any market for C919

"the orders of the three major airlines reflect that China, as the largest civil aircraft market, has strong market demand and development potential. At this time, ordering to buy aircraft also reflects the expectations of the three airlines for the recovery of the civil aviation market in the future." Lin Zhijie, an expert of civil aviation resources network, said

lixiaojin, an expert of civil aviation resource network, pointed out that the first thing for new aircraft orders is the need to replace old aircraft. By the end of 2021, the number of transport aircraft in the civil aviation industry at the end of the period was 4054, an increase of 151 over the end of the previous year. According to the average aircraft age of CAAC of 6-7 years, combined with other factors such as business volume growth, at least 200 new aircraft should be purchased every year. "Considering that these aircraft are delivered over several years, the quantity is reasonable."

according to the 2021 world air transport statistical report released by the International Air Transport Association, China will become the world's largest aviation market for the first time in 2020. Compared with the increasingly saturated European and American aviation market, China's aviation market is full of toughness

during the 13th China International Aerospace Expo last September, the market forecast report (2021-2040) released by COMAC estimated that in the next 20 years, China will become the largest market for the delivery of new civil aviation aircraft, receiving 9084 passenger planes with 50 seats or more, accounting for 20% of the world, with a value of about $1.4 trillion. Among them, there are 6295 single channel jetliners above 120 seats and 1836 double channel jetliners above 250 seats. By 2040, China's aircraft fleet will reach 9957, accounting for 22% of the global passenger aircraft fleet, becoming the world's largest single aviation market

"hundreds of imported airliners will not impact the sales of C919." Aviation blogger "aviation story" believes that since C919 has not been delivered yet, it is normal that Airbus and Boeing will still dominate domestic aircraft orders in the short term

"this order has a total of 292 aircraft, which is equivalent to the number of aircraft introduced in the whole industry in one year before the epidemic. The aircraft will be delivered in 4-5 years, and the quantity cannot meet the transportation capacity needs of airlines in the next few years. Chinese airlines also need to buy more aircraft in the future." Lin Zhijie analysis

moreover, as a new aircraft, C919 adopts more advanced technologies in its overall design and has a higher degree of automation. Compared with similar aircraft, it has certain advantages in safety, economy, environmental protection and comfort. For example, the high-efficiency air filtration system used provides high-quality fresh air; With advanced aerodynamic design, the aerodynamic resistance is smaller than that of similar aircraft; The advanced power system, exhaust and noise emissions are more than 50% lower than those of existing aircraft
