The domestic large aircraft C919 realizes the first long-distance flight

On November 10, China Commercial Aircraft announced that the first aircraft of the domestic large-scale passenger aircraft C919 is scheduled to transfer from Xi'an Base to Xi'an. This indicates that the C919 inspection flight test in Shanghai has come to an end and has begun to enter the next step of research and development flight test and airworthiness. The transition flight will be the first long-distance flight of the C919. From the perspective of the project, it means that the large passenger aircraft project has been transferred from the initial inspection flight test to the envelope expansion test flight.

During the transition, the C919 will fly at a speed of up to 26,000 feet and a speed of less than 300 knots. The altitude is comparable to that of a normal civil aviation flight, which is slightly lower than the normal flight, but far higher than the height of the first flight. speed.

Since November 8, the COMAC C919 passenger plane took off from the fourth runway of Pudong Airport. This is the fifth test flight of the first aircraft. The transfer flight will have a business jet piloted by the C919. The pilot crew will establish communication with the C919 aircraft crew through the dedicated frequency of the test flight, and notify the current position of the pilot aircraft according to the cooperative method. If the dangerous weather is detected, the pilot aircraft will be sent to the C919 aircraft crew. Notify the weather related information and provide suggestions for the flight direction.

In terms of ground support, the transfer route and related landing and landing sites have been clearly defined, and various guarantees such as airspace, meteorology, and navigation guidance have been completed, a series of maintenance inspections and inspections, control and handling of flight test issues, and transitions. The relevant preparations for telemetry and ground support are also in place.

For China's domestic large aircraft C919, in order to enter the international market, it is necessary to obtain a foreign airworthiness certificate. Next, after the first aircraft of the C919 is transferred to the Xi'an Yanliang test flight base, it will invest more heavy airworthiness forensics flight test. The development of safe aircraft in accordance with international standards is a principle that has been followed by COMAC.

The Civil Aviation Administration of China (CAAC) accepted the application for the C919 type certificate in 2010 and carried out the corresponding airworthiness review in accordance with the procedures. After careful consideration, the C919 large passenger aircraft applied for the European Aviation Safety Agency (EASA) type certificate and has been accepted. Wu Yue, general manager of China Commercial Aircraft Corporation C919 large passenger aircraft project, said, “Our forensic environment is definitely getting better and better, including Europe. We have also reached a bilateral relationship with EASA (European Aviation Safety Administration). Our country is airworthy. In terms of regulation, once the bilateral is over, it will be very helpful for the C919 to enter the US market in the future, because the FAA (United States Federal Aviation Administration) recognizes it in many countries, which is undoubtedly very meaningful and beneficial."

From the first flight on May 5 this year, the first aircraft of the C919 aircraft completed a total of multiple skid and five flight tests, detailed control of the aircraft's characteristics, preliminary inspection of aircraft air data, handling quality, and flight control, The working conditions of hydraulics, engine, landing gear, APU, fuel oil, environmental control, avionics and power supply have eliminated the problems affecting the safety of the transition flight. At present, the number of domestic and foreign C919 domestic passenger aircraft has reached 27, the total number of orders reached 730, and the confirmed orders and intention orders accounted for about one-half each.
