To support the process automation of reliability analysis and assessment for avionics system,an AADL reliability analysis tool(ARAT)was designed and implemented. The functional requirement for ARAT are illustrated with the use case dia-gram and the interactive process between two functions is described by the activity diagram. The deployment and implementation of the function modules in the tool are presented. The reliability of the airborne equipment is evaluated to demonstrate the effec-tiveness of design idea and method of ARAT,which provides a support for evaluating system design schema,and evidence for the development process and safety objectives to meet the airworthiness standards of avionics system.
