In May this year, the first domestic C919 large aircraft delivered by COMAC Group, , performed well in all indicators and parameters, and was successfully delivered and used through assessment. my country's domestic aircraft has gone from scratch. After half a century of research and development and construction, what does the first domestic aircraft independently developed mean now?

my country has used aircraft produced abroad for many years. Even if civil aviation companies are increasing, the independently developed aircraft have not been successful for a long time. The aircraft are often hundreds of millions of yuan each, and not a few aircraft are enough when purchasing. China's civil aviation market has a very vigorous demand growth, which has also made foreign aircraft manufacturing companies make a fortune in the Chinese market.

Now China can independently develop and build aircraft, breaking the monopoly of foreign civil aviation manufacturing companies in China. Moreover, with its good aircraft manufacturing technology, China will be able to participate in international competition in the future and seek the development of the international market for aircraft made in China. This has positive significance for promoting the integration of my country's civil aviation industry with the international level, and for allowing more countries in the world to enhance their understanding of China and promote cooperation.

Now my country's C919 large aircraft is the stable delivery of the first batch of orders. Mass production and testing are being stepped up. China's aircraft can not only add new aircraft options to domestic routes, but also conduct bilateral cooperation with international routes from more than 20 other countries. That is to say, although the United States is now looking for various reasons to delay the method of not giving my country's aircraft airworthiness certificate , my country's domestic aircraft can cooperate with the same routes as international airline that is launched to my country. The United States cannot stop the development of Chinese aviation, nor can it stop the takeoff of Chinese domestic aircraft.

In addition to the first domestic C919 passenger aircraft , the wide-body passenger aircraft C929 page cooperated with my country and Russia is in a stable promotion, because of concerns that the supply parts of , the supply of in Western countries will be cut off, which will lead to the overturning of the plan and redesign of the wide-body passenger aircraft during the research and development. Moreover, Russia also intends to withdraw in the middle, but later Russia still considers the trade-offs and considerations and needs to complete the development of this aircraft with China.

Currently entering stable mass production and delivery of domestic aircraft C919. The first domestic order is China Eastern Airlines' 100 aircraft. These aircraft will be gradually increased to the branch lines of domestic routes, playing a role in promoting the prosperity and development of my country's civil aviation.

my country's journey of developing aircraft is a bit long and arduous. It has been more than half a century. Several generations of aviation R&D workers have contributed their lifelong hard work and talents to China's aircraft industry. The most core problem is stuck in aviation engines. Now after many breakthroughs, my country has achieved self-sufficiency in domestic aviation engines, and the first domestic aircraft is also expected to load the center core. The successful development of the first C919 means the epoch-making process and important achievements of China's civil aviation industry.

The domestically produced C919 passenger plane designed and produced in my country is affectionately called a large aircraft by the Chinese. Although many netizens did not understand the early stages of construction, and why the aircraft that used more than 60% of foreign parts were still called domestic? After the relevant experts explained, many people finally realized it.

When my country impacted the international civil aviation market, it wanted to leave room for cooperation and express sincerity for civil aviation companies in other countries. So it outsourced some foreign aviation manufacturing companies with mature production experience in parts orders, with the purpose of indicating that China's new aircraft and cooperation with World Airlines also left market share, and it was not necessary to solve them all by itself when it came up.

However, in order to avoid the outage of supply of aircraft parts in my country due to unreasonable interference from Western countries, my country will produce independently in stages after the imported parts are assembled. In the end, the parts of my country's domestic aircraft can be fully domesticated by 100%, so netizens don't have to worry at all.

my country's China Eastern Airlines, as the first user of C919, has begun to receive aircraft and start training pilots. It is also the first airline to operate C919.

This aircraft has advanced design and exquisite manufacturing technology. After multiple sites and long-term testing, all parameters show strong overall strength, which is completely inferior to the benchmark models of the American Boeing 737MAX and French Airbus A320.

More importantly, the overall cost of my country's C919 large aircraft is more competitive, with a unit price of more than 90 million US dollars, while the unit price of Airbus and Boeing both exceeds 110 million US dollars. Don't underestimate the difference in unit price of 10 million or 20 million US dollars. When purchasing airlines purchase ten or dozens of aircraft, the price difference is very amazing. The price difference between

10 aircraft is close to US$200 million. For airlines, with the same functions and quality, as well as carrying capacity and fuel consumption, why not choose a more cost-effective aircraft? Procurement of this Chinese-made aircraft and save money is equivalent to starting to make money since ordering. What's more, Chinese airlines have higher after-sales service and reputation, better service attitude, and more reliable cooperation. So why don't many airlines that need to purchase aircraft?

China's civil aviation aircraft has broad prospects in the future and there is great potential for the market.
