This paper presents a method of achieving high mission reliability with a COTS (Commercial Off-the-Shelf) based system in a military environment. Reliability of COTS as compared to mil-spec components and systems is the major issue encountered in military applications. The severity of the problem depends on the operational environment and mission profile. This paper presents the design analysis and trade studies employed to develop a flight critical COTS based system. Three primary approaches of applying COTS to military aerospace systems are analyzed, with the data presented to support a design approach. These approaches include: BIT (Built-in-Test), redundancy, and graceful degradation. The design limitations to each approach are analyzed and the impact on mission reliability is discussed using the results from trade studies. This paper concludes with the results from a reliability study of a flight critical system - an electronic sequencer for an ejection seat - that employs COTS based design.
