2025, EASA Part IS in U-Space Operations: Is System-Theoretic Process Analysis for Security Sufficient to Meet Information Security Risk Assessment Requirements?, Linz, Elsevier BV), p. 2448-2457), ISSN 1877-0509

The U-space implementation within airspace management has led to the emergence of research activities focused on information exchange between U-space stakeholders. U-space requires information exchange among various entities, including the Air Navigation Service Provider, U-space Service Provider, Common Information Service Provider, Unmanned Aircraft Systems, and remote pilots. This information must be secured. European Part-IS addresses information security risks by establishing processes to safeguard information used, transmitted, or received during U-Space operations. This paper investigates whether the System-Theoretic Process Analysis for Security (STPA-Sec) can ensure compliance with EASA Part-IS information security risk assessment requirements. By applying the analysis to the CISp operation concept and comparing the outcomes with Part-IS requirements, the results indicate that while STPA-Sec effectively identifies potential security vulnerabilities and hazards, it does not provide specific mitigation recommendations. Therefore, while STPA-Sec can inform the development of security strategies, additional steps are needed to fully comply with EASA Part-IS requirements.

This paper explores the integration of System-Theoretic Process Analysis (STPA) in Model-Based Safety Analysis (MBSA) for aircraft safety assessment, using the electrical system of the Cessna C510 Citation Mustang as a case study. It highlights how each method's unique strength, i.e., STPA’s focus on system interactions and MBSA’s detailed system modeling, complement each other to provide a more comprehensive safety analysis. The integration demonstrates improved hazard identification and safety assessment, suggesting this combined approach could significantly enhance the safety process in aircraft systems. The findings support the efficacy of merging STPA and MBSA, aligning with modern safety engineering guidelines and opening pathways for future research in complex system safety analysis.

Flight procedures are one of the main pillars for the safe performance of a flight. However, sometimes flight procedures must be modified. The need to modify them may arise from operational experience or a safety study. One of the methods that can be used to perform a safety study for the purpose is System-Theoretic Process Analysis (STPA). The goal of this paper was to perform a safety assessment of the Cessna 172 flight procedures based on a proactive systems approach to safety, using STPA. The goal was to identify potential safety issues related to selected flight procedures and to propose corrective measures or safety recommendations that could be used in practice. The results show how to work with STPA in the context of flight procedures and what measures or recommendations emerged from the analysis for the Cessna 172 flight procedures. The analysis confirmed the possibility of using system safety approach in general aviation to assess flight procedures and usefulness of its results.

To conduct reliability studies, Fault-Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA) are among the most used methods. However, with the emergence of software and complex modern systems, such analyses are not sufficient anymore. Therefore, System-Theoretic Process Analysis (STPA) was created to solve such problems and conduct safety analyses but was never used for a reliability analysis. This paper presents a reliability study of the Wheel Braking System (WBS) of the Cessna Citation Mustang using STPA, and a comparison study using FMEA. Outputs of both methodologies were compared and showed that STPA produces better results.
