Like all his colleagues at the Commercial Aircraft Corporation of China (COMAC), Cyrille Breard, the manager of the C919 program's noise and emissions project, is working against the clock as China's domestically-made passenger plane is undergoing a series of tests before acquiring its airworthiness certificates.
The responsibility of Breard and his team is to lower noise uncertainty of the new jetliner, which will not only guarantee a safe and environmentally friendly flight, but also provide passengers a quieter journey.
Too much noise will also shorten an aircraft's service life, he said.
