Developing large airplanes, with 100-ton and greater cargo or 150-passenger and greater capacity, has become a key component in promoting the development of aeronautics industry in China’s 11th “Five-Year Plan.” China will, at an appropriate timing during the 11th “Five-Year Plan,” launch the R&D of large airplanes, said Jin Zhuanglong, spokesperson of the Commission for Science, Technology and Industry for National Defense, or COSTIND.

China’s first large plane, a 178-seater called “Yun-10” under support of Chaiman Mao and Premier Zhou, did successful testing flights in 1980 but didn’t enter commercial production.
