Abstract
System safety is the principal driver of avionics system requirements and has caused more and more attention. For the reason that the main concern of avionics system research is system capacity and constitution since early safety analysis, system reliability has become dominant trends for studying system effectiveness. With the avionics system becoming more and more complex, the traditional research methods which are used in studying system reliability, faces the challenges of organizing problem for multiple system goals, multiple processes, multiple elements, multiple relations, and multiple conditions. To solve the problem of safety analysis for integrated avionics system, hazard and mishap modes of avionics system are studied and the methods of risk analysis, risk evaluation, risk controlling, risk elimination, and risk mitigation are presented based on the system risk controlling theory. Finally, the organizing and engineering technologies of system safety, software safety, and hardware safety are also discussed to provide foundation for designing integrated avionics system safety.
