This report documents the results of Phase 5 of the Aerospace Vehicle Systems Institute Authority for Expenditure (AFE) 43 Microprocessor Evaluations Project that provides research information intended to help aerospace system developers, integrators, and regulatory agency personnel in the selection and evaluation of commercial off-the-shelf microprocessors for use in aircraft systems. This report describes the cooperative research accomplished by contributing members of the aerospace industry and the Federal Aviation Administration (FAA). The project objectives included (1) identifying common risks of using a system-on-a-chip (SoC) and mitigation techniques to provide evidence that they satisfy regulatory requirements and (2) evaluating existing regulatory policy and guidelines against the emerging characteristics of complex, nondeterministic microprocessors and SoCs to support the certification of aircraft and qualification of systems using these devices. Complex aircraft system development requires more robust consideration of system failure and anomaly detection, correction, and recovery. The safety net approach identified in this report provides a means to address the lack of design assurance for highly integrated, complex, nondeterministic airborne electronic hardware within aircraft systems. Airworthiness assurance of these SoCs by safety net techniques may help to contain the labor burden and costs of compliance to FAA regulations while maintaining safety requirements as SoCs continue to become more complex and more widely used in aircraft systems.
