Aircraft comparisons between the Chinese-built comac C919 and the Boeing 737 max 8 

In this post, we’ll compare two narrow-body aircraft, one from the United States (the Boeing 737 Max 8 aircraft) and one from China (the Comac C919 aircraft), which was just domestically manufactured.

China is seeking a larger market to supply its aircraft to domestic and foreign customers. Eastern China Airlines has recently received delivery of its first aircraft. With regard to its Boeing 737 segment of aircraft, Boeing already holds the largest market share. Undoubtedly, if the Comac aircraft becomes widely used, Boeing may lose market share in China.

Let’s analyze the specifications of both aircraft.

Boeing B737-8. 

The Boeing 737 MAX is the fourth generation of the Boeing 737, a narrow-body airliner manufactured by Boeing Commercial Airplanes (BCA), a division of the American company Boeing. The first MAX 8 was delivered in May 2017 to Malindo Air, which began using it on May 22, 2017. A MAX 8 carrying 162 passengers on a 3,000 nautical mile (5,600 km) flight is anticipated to burn 1.8 percent less fuel than an airplane with blended winglets.

Compared to the A320neo, the MAX 8 is heavier at takeoff and has a lower empty weight. During a test flight for Aviation Week, the aircraft was flying at a less-than-ideal height while cruising at a real airspeed of 449 knots (832 km/h) and weighing 140,500 pounds (63,700 kg). The Boeing 737 MAX 8 completed its first flight test in La Paz, Bolivia. The 13,300-foot altitude at El Alto International Airport tested the MAX’s capability to take off and land at high altitudes.

In early 2017, a new B737-8 was valued at $52.85 million, rising to below $54.5 million by mid-2018, and the latest version is having a 200 Seater variant under construction for Ryanair. With a 160-passenger capacity, the 737-8 has so far been the most popular model.

Comac C919

A narrow-body airliner called the Comac C919 was created by the Chinese company Comac, and it had its inaugural flight on May 5, 2017. Not early than 2022 or 2023 is anticipated for the first commercial deliveries of the aircraft to China Eastern Airlines. Comac had 1008 pledges as of the end of August 2018, including 305 firm orders, many of which came from Chinese leasing companies or airlines.

At Shanghai Pudong International Airport, the C919 successfully completed its first pre-delivery flight test. According to Comac, the aircraft successfully finished a three-hour test session on May 14, 2022. This year will see the delivery of the aircraft in the livery of the Chinese company OTT Airlines, a division of China Eastern. The aircraft was listed in May 2022 for 653 million yuan (US$95 million), nearly matching the prices of the Airbus A320neo and Boeing 737 Max rivals and more than double the earlier estimate of US$50 million.
