One of the main challenges in front of China's aircraft manufacturers and airborne equipment suppliers is how to apply the airworthiness standards, such as ARP4754A, ARP4761, DO-178B(C) and DO-254, etc, into their engineering practice. Chinese companies are struggling in improving their capabilities to satisfy certification requirements and are making some remarkable progress these years. The paper first introduces the current status of Chinese aviation industry, and then the challenges to China's airborne equipment suppliers are analyzed.
