at around 11:23 on august 29, air china's c919 aircraft arrived safely at beijing capital international airport. the airport welcomed the large aircraft with the highest etiquette in civil aviation - the "watergate" ceremony.

captain wang yan, who was on the flight from shanghai to beijing, said: "i am proud of air china's c919 model, and i am also proud to be a c919 pilot."

air china's first c919 aircraft has new mysteries both inside and outside. beijing youth daily reporters will reveal them to you one by one.

the middle seat is 18.5 inches for increased passenger comfort

air china's c919 cabin has chosen air china's interior product "phoenix dancing in the clouds". the four products of chair fabrics, carpets, partition curtains and cloud-patterned wallpaper are coordinated and consistent, perfectly integrating air china and the domestically produced large aircraft.

the seats of air china's c919 aircraft are spaced farther apart, and the aisles are wider than those of ordinary narrow-body aircraft. air china's c919 aircraft has a total of 158 seats, including 8 business class seats with a spacing of 40 inches, 150 economy class seats with a spacing of 30-31 inches, and the spacing of emergency exit seats reaches 45 inches.

compared with other airlines' 164-seat layout, air china has reduced one row of economy class seats, so the seat pitch in each row has increased by 2 inches, which is better than the seat pitch of similar foreign aircraft.

a passenger who is 1.8 meters tall said that the legroom is quite comfortable and he can stretch his legs. when the passenger in the middle seat leaves the seat, the aisle passenger only needs to turn his body slightly to pass by.

air china's c919 aircraft also has an ingenious and original design in the seat layout, that is, the width of the window and aisle seats is 18 inches, and the middle seat is 18.5 inches. in this way, even passengers sitting in the middle position can get a comfortable ride.

seats with mobile device holders

in order to facilitate passengers to use mobile devices, this aircraft is designed with a separate bracket behind the seat. passengers press a button to lower the bracket to place mobile phones, pads and other devices. this position is higher than the dining table and parallel to the line of sight, making it more suitable for passengers to easily catch up on tv series.

a high-power usb-c charging port is designed under the seat, so passengers can charge their mobile phones, computers and other devices during the flight. air china is also the first airline to implement in-cabin wifi function on c919 aircraft, so passengers can watch movies and other media programs online.

performance characteristics of air china's c919 large aircraft

air china introduced the extended-range (er) c919, and is the only one of the three major airlines to choose this sub-model. compared with the basic model, the c919 extended-range has a larger maximum take-off weight (78.9 tons) and engine thrust (30,000 pounds), and a longer range. the full-load flight distance is 2,000 nautical miles, an increase of 700 nautical miles over the basic model, and the maximum range is 5 hours, an increase of 1.7 hours over the basic model, which has better market applicability.

the c919 extended-range version is equipped with two leap-1c30 engines, which have completely interchangeable life parts and blades (including rotor blades and stationary blades) with the leap-1a (a320neo series) engines, helping to improve the economy of the aircraft.

captain experience:

the c919 aircraft has reached a very high level in terms of design and performance.

captain wang yan said that he had flown boeing 777 and airbus 321 aircraft, and successfully completed the c919 conversion training in july 2024 and obtained a new pilot's license. the preparations for this transfer flight included routes, take-off and landing airports, alternate airports, weather, and abnormal situation plans.

"the first c919 aircraft is numbered b-919x. in my opinion, 'x' symbolizes the unlimited potential, supreme glory, responsibility and mission of domestic aircraft," wang yan said in an interview with beijing youth daily. "our domestic large aircraft c919 is a very excellent model. it has reached a very high level in terms of design and performance, as well as in terms of control feel and human-machine interaction. we must fly out of the brand and fly out of benefits to ensure that domestic large aircraft soar smoothly in the blue sky of the motherland."

wang yukun, deputy squadron leader of the 1st squadron of the 7th brigade of air china flight corps, said in an interview, "air china's c919 is a new aircraft model. we must not only master the operating skills, but also have a deep understanding of its principles and the knowledge behind it. during the theoretical learning stage, in order to fully grasp the knowledge learned during the day, we used the comac smart learning center to review independently at night. everyone raced against time and rushed to enter the systematic learning. everyone successfully completed the c919 model modification task with excellent results."
