The concept exploration stage of a dependable avionic system

The fault tolerant aspects of the evaluations and trade studies done in the concept evaluation stage of a mission avionics system are discussed. These studies are considered from the point of view of the government program office in charge of the RFP, SOW, design review and milestone deliverables. The author touches on some of the possible fault-tolerant specifications, a fault-tolerant evaluation criteria for the qualitative analysis of the design in the system requirements review (SRR) and system design review (SDR), and the wide range of possible fault injection methods and validation techniques.<>
