May 5 this year，my country’s first C919 aircraft successfully made its maiden flight，And transferred to Yan Liang in early November，Carry out subsequent 188bet Online Sports Betting and Casino subjects。Today (17th) morning，The second domestically produced large passenger aircraft C919 will conduct a 188bet Online Sports Betting and Casino in Pudong, Shanghai，This means that the development of the C919 large passenger aircraft has taken another critical step，The new journey of comprehensive 188bet Online Sports Betting and Casino is gradually starting。

As the second C919 aircraft to be tested，What test subjects will Aircraft 102 conduct next？These 188bet Online Sports Betting and Casino subjects are for the 188bet Online Sports Betting and Casino mission of C919 aircraft，What is its importance？

Verification of engine and other key performance

According to plan，Six C919 aircraft will be put into 188bet Online Sports Betting and Casino。The missions of these 6 aircraft have different focuses。Introduced by Wang Wei，The second C919 aircraft tested this time，Number 10102，In the future, the important system performance of C919 will be mainly tested，Especially the aircraft power system represented by the engine。

Wang Wei, Chief Engineer of COMAC Civil Aircraft Flight Test Center: We figuratively say it is the heart of the aircraft，Those fuel systems，Hydraulic system，Like the blood vessels that supply the heart。The aircraft power system that 102 aircraft focuses on is also very important，It is a very important link for our entire C919 certification 188bet Online Sports Betting and Casino。

Strive to start transition 188bet Online Sports Betting and Casino flights in January next year

Introduced by Wang Wei，Except today’s 188bet Online Sports Betting and Casino，The 102 aircraft will also conduct a series of 188bet Online Sports Betting and Casino subjects in Shanghai。Be prepared for transfer to other places。

Wang Wei, Chief Engineer of COMAC Civil Aircraft Flight 188bet Online Sports Betting and Casino Center: There are mainly 22 systems to be inspected in Shanghai，Then we will probably fly to more than 120 188bet Online Sports Betting and Casino points，We currently have 4 to 6 sorties scheduled to complete these missions。We strive to have the conditions for transition around the end of January，This is our current goal。

The road to 188bet Online Sports Betting and Casino of C919 will face many difficulties

As my country’s first independently developed large jet airliner，Many 188bet Online Sports Betting and Casino subjects of C919 are the first time for my country’s civil aircraft industry，Not only difficult，And the risk is high，These are the difficulties that the C919 will face in future test flights。

To ensure safety，C919 needs to fully understand its own limit，This requires repeated 188bet Online Sports Betting and Casino flights to obtain。Especially stall、Subjects such as chatter and natural icing are extremely risky，In case of error，The consequences are unimaginable。

Wang Wei, Chief Engineer of COMAC Civil Aircraft Flight 188bet Online Sports Betting and Casino Center: What is the concept of stall？If the plane is not controlled well，The aircraft speed is gone。Once the plane loses speed，It will fall off。So what is the small speed of these things？What is the maximum speed？What is the height？It all depends on us actually flying out in the air。

Except for the risks of test flights，The C919 188bet Online Sports Betting and Casino team still faces technical difficulties。Because C919 adopts the most advanced systems and equipment in the world，How can the 188bet Online Sports Betting and Casino crew master these new technologies and equipment，And be able to obtain data in accordance with the 188bet Online Sports Betting and Casino terms，It is also a hard nut for flight test work。

Wang Wei, Chief Engineer of COMAC Civil Aircraft 188bet Online Sports Betting and Casino Center: For example, our avionics system，Including our flight control system，Includes the materials we use，There are also some new technologies，The application of these new technologies has brought higher challenges to our flight 188bet Online Sports Betting and Casino verification。

Wang Wei said，The comprehensive flight 188bet Online Sports Betting and Casino work of C919 has just begun，In the next few years，In order to obtain the final airworthiness certificate，Obtained the qualification to enter route operation，C919 needs to complete more than 1,000 188bet Online Sports Betting and Casino verification items。
