The demand on software safety assurance in domestic military aircraft development has been increasing as use of software has rapidly expanded in the aerospace industries. MIL-STD-882E, the representative military system safety standard, requires military aircraft development programs to assign Software Criticality Index on their software in the early stages of developments for determination of software safety assurance tasks. Previous studies emphasized the need of Software Criticality Index assignment on military air-system software for airworthiness certification and proposed the methodology of Software Functional Hazard Analysis to meet the requirement. Despite of the current military airworthiness requirement, domestic experience on software safety has been insufficient yet. This study complements the Software Functional Hazard Analysis methodology utilizing fault tree analysis and flow chart for objectivity and performs analysis on a flight data display system to assign appropriate Software Criticality Index on the safety significant software. The analysis result is then compared with similar advanced cases. This thesis will be an useful reference of software safety assessment for future developments of domestic miliary aircraft and systems.
