China's first group of five carrier-borne jet pilots and landing signal officers received their certifications in the latest sea trials of the Liaoning, the country's first aircraft carrier, Xinhua News Agency reported on July 4.

The Liaoning finished its 25-day test and training mission on July 3. Using the J-15, China's first-generation multi-purpose carrier-borne fighter jet, pilots finished China's first training mission stationed aboard the carrier as well as the first 105-meter short-distance ski-jump takeoff exercises.

Pilots and landing signal officers were tested on a range of skills. They passed the certification process following expert reviews and a flight data assessment.

Zhang Yongyi, Commander in Chief of the aircraft carrier tests and sea trials, said that China has successfully established a training system for carrier-borne jet pilots.
