China's ARJ21 regional jetliner flies new routes in extreme cold region

China's home-developed ARJ21 regional jetliner on Wednesday began to fly on new routes in northeast China's Heilongjiang Province, said its developer.

The opening of new air routes with ARJ21 represent the model's commercial flight operations in the country's most northern and extreme cold region, said the Shanghai-based Commercial Aircraft Corp. of China.

The new air routes include the 3,200-kilometer-long route between Harbin and Chengdu, capital of southwest China's Sichuan Province. It stops by Jinan in east China's Shandong Province.

ARJ21 will also be used in another four new air routes in Heilongjiang, namely Harbin-Heihe, Harbin-Wudalianchi, Harbin-Fuyuan and Fuyuan-Jiangmusi direct air routes.

Chengdu Airlines will be the operator.

ARJ21 is China's self-developed regional jet with 78 to 90 seats and a range of up to 3,700 km. It acquired certification in December 2014 and made its maiden flight in June 2016.

Mass production started in September 2017.
