In an event of a test model plane crash, an emergency recorder and tracking system is separated from the tail section of the plane, China's News Agency (Xinhua) reported.
The test, which is shown in a video clip, is part of a series of tests completed since October by the U.S. subsidiary of the Commercial Aircraft Corporation of China (COMAC) on a comprehensive emergency information recorder and tracking system.
COMAC America Corporation says its emergency recorder system includes a data storage and transmitter called Harbinger, claiming for the system it had been applying new methods that transcend traditional designs of black box recorders used in commercial aircraft.
A traditional black box emits distress signals for 30 days after sinking with the plane. It stores 30-minutes of cockpit voice conversation and two hours of flight data before the crash.
The system can also save a copy of the data and is equipped with a parachute and inflation system to enable it to stay afloat at sea. The inflation system can also protect hardware when the Harbinger lands on hard surfaces. It will also transmit distress signals to help rescue teams locate its position.
The company has filed a patent application of the Harbinger emergency system with the U.S. Patent and Trademark Office, said Ye, adding that "we believe new models of commercial aircraft in the future will benefit from using this system."
