China expects to deliver its domestically developed AG600, the world’s largest amphibious aircraft, to customers by 2022, Xinhua reported late on Sunday citing the plane’s manufacturer. “We are endeavouring to get the airworthiness certification from the civil aviation authorities by 2021 and deliver it to the customers by 2022,” Xinhua quoted Huang Lingcai, the plane’s chief designer at state-owned Aviation Industry Corporation of China, as saying.
