<ul><li>Autonomous flight termination systems (AFTS) are being progressively employed onboard launch vehicles to replace ground personnel and infrastructure needed to terminate flight or destruct the vehicle should an anomaly occur.</li><li>Key distinctions exist between crewed and uncrewed AFTS, including design philosophy, fault tolerance, and unique requirements for crew safety and human rating standards.</li><li>The AFTS software architecture consists of Core Autonomous Safety Software (CASS), Wrapper, and Mission Data Load (MDL), with guidelines for their use and recommendations for developmental use.</li><li>To achieve human-rating certification for AFTS software, guidelines such as those outlined in NASA documents and safety considerations for repurposing commercially available flight termination systems should be followed.</li></ul>
