China's independently-developed large amphibious aircraft, the AG600, has completed trial ground flights and entered a new test phase on the water-surface.

中国自主研发的大型两栖飞机AG600已经完成地面飞行测试，现在已经进入水面测试阶段。

The AG600, codenamed "Kunlong," successfully finished a trial flight from an airport in the city of Zhuhai, south China's Guangdong Province, to an airport in Jingmen, a city in central China's Hubei Province, on Sunday, according to China Aviation Industry General Aircraft Co. Ltd.

The company said that it marked the start of a new journey for AG600 -- a test phase on the water.

The aircraft passed a series of tests since its maiden flight last December. Next, it will conduct tests and trial flights on the water, in Jingmen.
