| Abstract | With flight software becoming ever more complex, assuming that it behaves perfectly is no longer realistic. At the same time Verification and Validation (V&V) is consuming up to 50% of flight software development costs. The adaptation of fault protection concepts to flight software is attractive, particularly in the context of the fault containment and health management capabilities of ARINC 653. We propose a proactive, unified, model-based approach in which the behavior of the software is monitored against a model of its expected behavior. We describe how that may be incorporated into the ARINC 653 health management architecture. We describe software capabilities that facilitate software fault protection. These capabilities include enhancements to the ARINC 653 application executive, tools for software instrumentation, and a temporal logic runtime monitoring framework for high-level specification and monitoring. We analyze the aspects of the software that should be modeled and the types of failure responses. We show how these concepts may be applied to the Mission Data System (MDS) flight software framework. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
