On September 30, my country's authoritative media reported that the C919 domestically produced large aircraft developed and manufactured by my country has obtained the model certificate in Beijing, the capital. C919 actually obtained the model certificate on September 29, but it was not publicly announced until September 30. From the point of time, the C919 completed its first flight on May 5, 2017, and the model certificate adopted on September 29, 2022, in terms of the speed of evidence collection, the C919 is slower than the Airbus A320 and Boeing 737 aircraft, which can't help but make people question why the C919 needs such a long test flight.
First of all, China is not as experienced in Europe and the United States in manufacturing large civil aviation aircraft. This is because China started significantly late, and now it is necessary to manufacture large aircraft according to the airworthiness standards of Western countries, which obviously takes longer. In addition, the world has been affected by pneumonia caused by the new coronavirus during the period before the C919 was carried out. It is precisely because of the impact of the new crown epidemic that some test flights of C919 have been delayed. Whether it is the Airbus A320 or Boeing 737 aircraft, there is no interference from external factors such as the new crown epidemic before the test flights and evidence collection. Therefore, Zhan Yan believes that the speed of C919 is slower than that of , Airbus and , Boeing , and two aircraft of the same level are also very supportive.
Today's Boeing 737 has become the target of public criticism, because there have been many fatal accidents in Boeing 737. Although Boeing has shown that Boeing 737 MAX series aircraft have design defects and have improved these defects, the frequency of accidents in the Boeing 737-800 passenger aircraft and Boeing 737-400 cargo aircraft in recent times has been significantly higher than that in Airbus, so China has chosen more Airbus A320 NEO aircraft in the process of purchasing aircraft in recent times. It is understood that China purchased the A320 from Airbus in 2022. The number of NEO aircraft has exceeded 300. After the C919 evidence collection, some media raised questions, what is the difference between the safety performance of the C919 aircraft and the Airbus A320 and Boeing 737? The test pilot has made a clear statement now.
According to media reports, the test pilot of the C919 aircraft has pointed out that he believes that the C919 aircraft is safer than the Airbus A320 aircraft. At the same time, in terms of its flight experience, he believes that the C919 aircraft will fly better. The test pilot even pointed out that if there is an aircraft selection on the same route in the future, he will choose the route operated by the C919 aircraft, because all the performances of the C919 are flew out by them personally, and they are quite confident about the safety of the C919.
For civil aviation aircraft, fuel economy and comfort can be shipped backwards, and safety is a crucial indicator. It can be seen that although the Boeing 737 MAX series aircraft continues to indicate higher fuel economy and higher comfort, two fatal accidents have made Boeing the target of public criticism, and Boeing's debt ratio is still soaring now.
