Historical Aerospace Software Errors Categorized to Influence Fault Tolerance
Abstract
- Motivation - Very little literature exists characterizing software errors in real-time avionic systems - How, where, and why is software most likely to fail? - Purpose - Raise awareness of how software fails through historical study - Recommend improvements to software fault tolerant design based on historical study - Outline - Discuss Software Failures - Common Cause, Failure Classes, Mitigation strategies - Review NASA requirements for Software Fault Tolerance - Review Historical Software Failures - Analyze failures and provide statistics - Erroneous vs. fail-Silent - Reboot recoverability likelihood - Code Location - Missing or unknown code?
