Abstract
In this paper a method for eliciting airborne software safety requirements (SSRs) is presented. Software FMEA (SFMEA) is applied to derive SSRs so as to improve airborne software safety. SFMEA is a popular analytical methodology for software reliability and safety analysis. A potential failure-cause-base for airborne software is built to support SFMEA. Analysts can establish recommended actions to the failure modes according to the results of definition of failure modes and potential causes. The potential cause base is used to ensure the completeness of potential cause investigation since currently it depends more on analysts' domain and safety knowledge. Then SSRs can be elicited referring to recommended actions established by SFMEA. And the processes for updating the cause base are established. At last this method is applied to aircraft engine control software in which the feasibility and effectiveness of this method f is demonstrated and software system safety is improved by this work.
