The importance of UAS Reliability ,[object Object],[object Object],[object Object],[object Object],[object Object]
Why to manage the Reliability of UAS ,[object Object],[object Object],Fault Error Failure Internal State External State UAV Component Information UAV behavior deviates from specification Fig 1.  Fault vs. Error vs. Failure

What management tools are relevant to UAS ,[object Object],STAGES TOOLS APPLICATION IN UAS FRACAS Analysis of UAS field data Aid in choosing the best design of the UAV platform FMEA Aid to validate the design parameters of the UAS DESIGN Failure Modes and Effects  Analysis from UAS similar or previous versions FTA Qualification and Validation of the UAS design  RELIABILITY  Calculate RAMS parameters based on the UAS life data FAULT PREDICTION Estimate the reliability or failures probability in UAS systems via RDB MANUFACTURE ESS Remove latent failures of UAS FMEA Identify faults in the UAS manufacture FRACAS  Data collection, analysis and corrective actions OPERATION Highlight critical points that need improvements FTA Assess the impact of changes introduced by UAS hardware and software Investigate the causes of field failures, or accidents with UAS MAINTENANCE FTA When we want to focus on a specific system failure Assist in management activities for major COTS components of UAS maintenance FMEA Aid the fault diagnosis process FRACAS Record of failure analysis and corrective and/or preventive actions in UAS
How they can be implemented in UAS’ life cycle phase   ,[object Object],[object Object],Fig. 3: For a series system of UAS operating successfully, all components must be operate successfully.
How they can be implemented in UAS’ life cycle phase ,[object Object],[object Object],FMEA and FTA are compatible tools of UAS risk analysis, being that the choice of proper tool depends on risk nature to be evaluated. However, FMEA considers only single failure in its analysis while FTA considers multiples failures, requiring a greater skill level than FMEA. When an UAS is designed, the modes it might fail can be captured in a FTA and FMEA. After the UAS is launched to field operation, the modes in which the UAS has failed can be captured through FRACAS and this knowledge can be used to update the FTA of the UAS in study. Table 2:Use of FTA, FMEA and FRACAS to detect faults in UAS     FMEA FRACAS General “ proactive” “ reactive” Purpose affect the UAS design before launch correct problems after launch Errors may occur – the potential errors  must be enumerated have occurred – observed errors are simply counted Error rate is assumed is measured Issues with technique Is it complete? Models can be wrong. All errors counted? Culture inhibits  reporting errors.  Can be combined with FTA FTA Evaluate quality of the technique difficult – completeness, reasonableness of mitigations is qualitative simple -  measure error rate
