Navy fault tolerant validation efforts

Two 6.3 and 6.4 efforts to clarify the US Navy´s management of the design of complex, computer based weapon and avionic systems are described. The 6.3 effort, the Advanced Avionics Technical Demonstration (AATD) Fault Tolerance Demonstration, is focused on the fault tolerant specifications, validation techniques, and acceptance tests of any future naval avionic system. These specifications will clarify the fault tolerance metrics for each design review for future Navy avionic systems regardless of the standards used. The 6.4 effort, the Next Generation Computer Resources (NGCR) Fault Tolerant Task Group, is concerned with the fault tolerance features of the Navy´s next-generation open system computer standards. This effort will ensure that future designers are able to adequately implement the AATD fault tolerance specifications using the NGCR standards
