BEIJING, Oct. 25 -- China's AG600 large amphibious aircraft on Friday passed an airworthiness validation flight test of its minimum unstick speed, the Aviation Industry Corporation of China (AVIC) has announced.

China's independently developed AG600 aircraft underwent the flight test in Pucheng County of northwest China's Shaanxi Province, said AVIC, the country's leading aircraft manufacturer.

The minimum unstick speed test is one of the most difficult and high-risk flight tests for transport aircraft. It is of great importance to ensure the safe formulation of an aircraft's takeoff and landing speeds.

The successful completion of this flight test has laid a solid foundation for the AG600's subsequent safety flight tests and airworthiness certification, according to the aircraft's developer.

The AG600 amphibious aircraft family is China's first independently developed, large-sized, special-purpose civil aircraft family. It is tailored to meet the needs of forest firefighting, maritime rescue and other emergency rescue sectors across the country, AVIC has said.
