SW and HW Certification: Future Challenges and User Initiatives to address them
On the software side, the presentation will introduce the transition between DO178B and DO178C documents, and the associated regulation. On the hardware side, clarifications in the DO254 context are still necessary after 10 years of experience and will be highlighted. To deal with those challenges, the Industry created some initiatives in order to identify the practical issues, share experiences and propose ways to solve the issues, in relation with Authorities. Such initiatives, like the DO254 User Group of the Forum of Aeronautical Software, will be introduced as well.

Reducing Complexity of Advanced Integrated Systems: Impact on Certification
IMA architectures target the reduction of aircraft operation and maintenance costs. They are designed to reduce electronic control unit (ECU) cost, improve the commonality of parts, minimize the number of computing modules, and reduce wiring, the number of connectors and weight. Beyond obvious weight and maintenance complexity reduction benefits, IMA supports design of new integrated functional capabilities which could not be implemented in a federated system. IMA systems consist of DO-254 and DO-178 certifiable components and modules, which can be utilized to design a range of integrated embedded platforms according to DO-297 guidelines. IMA relies on embedded resource sharing which is essential for design of advanced integrated systems, and imposes a significant stress on system architects providing evidence on correct behavior of a huge number of interactions and interfaces in the system. In order to prevent exponential complexity increase for those critical integrated systems, different embedded platform architecture patterns can be applied. In this presentation, different approaches for minimizing system complexity and certification effort for future architectures will be presented.

Certification of On-Board Electronics In China
The presentation introduces the publication process of China’s CTSP standards, as well as the research and launch route of CTSO standards by the Civil Aviation Administration in the short future; the speaker will review the certification progress and evidence obtained for on-board electronics, discussing key issues for airworthiness certification, and possible requirements from the authority, possibly on structural design assurance system, quality and configuration, software and hardware verification, cosmic radiation, environmental test capabilities, etc.

Process Improvement In ACTRI Context
Certification is one of the challenges of Chinese aviation companies with the development of their civil aircraft program. The presentation will introduce ACTRI successful practice in SW&AEH process improvement in the past few years. Also, the safety analysis of some special systems (such as IMA, airborne network, etc) are proposed to discuss at the end of the presentation
