As a "good partner of the trunk liner", since C909 aircraft was put into commercial operation in 2016, a total of 150 aircraft have been delivered, safely carrying more than 17 million passengers. COMAC has continually promoted product improvement and optimization to unceasingly improve the performance, the crew operation experience and the cabin comfortability of C909 aircraft. Now, C909 aircraft is available in a variety of cabin layouts, including a two-class layout with 78 seats, an all economy-class layout with 90 seats, and a high-density economy-class layout with 95 or 97 seats; has excellent take-off and landing performance and crosswind resistance at airports with short and narrow runways in severe cold, high temperature and plateau conditions; and has strong adaptability to the operating environment in border areas of China and overseas regions such as Southeast Asia and Africa. C909 aircraft is suitable for relying on regional airports or sub-hub airports to build route networks and supplement transport capacity for hub airports. In addition, C909 aircraft can carry out commercial flight using Sustainable Aviation Fuel (SAF) with a mixing ratio of up to 50% to meet the diversified demands of customers.

　　With the comprehensive transformation of the trunk liner program from development phase to industrialization phase, large-scale and serialized development is steadily advanced, and more and more China-made commercial aircraft are put into route operation. COMAC's unifying the names of aircraft products is conducive to shaping the image of serialized products and further enhancing product identification and brand influence. COMAC will continue to deliver commercial aircraft products which are safer, more economic, more comfortable and more environmental-friendly, and inject more COMAC wisdom and strength into the development of the global air transport industry.
