Safety of complex aircraft ergatic systems

101--110

In this paper, aircraft safety of complex critical systems in terms of the automation and safety has been investigated. We think, due to the automation, the role of operators has shifted from active control to passive monitoring. Performing this last task even might be more difficult because of the monotony and needs of realization of the active control in emergency situation. The management of complex ergatic systems is relevant at the present stage of the development of science and technology. It is a particular concern to evaluate the activity of an operator as the element of the ergatic system. New technologies presented by automation should complement and not displace human functions in aircraft control. The paper focuses on new technologies applied in aircraft systems to ensure higher safety and system reliability. The main problem of aircraft safety is addressed to aircraft critical systems as helicopter transmission system monitoring, aircraft system integration, and system redundancy. The research is based on experimental methods and case studies. The subject of the research is to evaluate the importance of complex ergatical systems, e.g., interaction between the subject and the object in its operational process. As the example of helicopter main gearbox diagnostics, as an object of complex engineering system, is stated hypothesis that there is possibility to determine changes in the characteristics of critical flight parameters and to determine the current level of flight hazard. The work is based on experimental and measurementbased testing, systematic and scientific procedure of data collection, analysis and interpretation. The practical implication can be utilized for safety benefits, risk mitigation and avoidance.

Development of quality management system under ISO 9001:2015 and Joint Inspection Group (JIG) for aviation fuelling service

The Joint Inspection Group (JIG) standard for aviation fuel quality management assists in the operational process and maintenance of aviation fuel from its point of origin and through distribution systems to airports. Currently, problems arise as the JIG standard and quality management in aviation fuel are isolated and have independent procedures. Merging the JIG standards with ISO 9001:2015 can override original JIG’s philosophy by connecting all quality assessment, and management parties involved, throughout the supply chain. This integration can harmonize auditing tasks, focusing on risk/opportunity, and continue quality improvement focus. This paper proposes a development of quality management system (QMS) under ISO 9001:2015 for aviation fuelling service in a systematic way. The content and critical success factors of ISO 9001:2015 and JIG standards were studied. The beneficial synergies, similarities, and logical linkages between both standards are identified. This QMS was developed in the largest petroleum company in Thailand and 60 selected experts were surveyed, with a response rate of 88.3%, for their agreement on integrated criteria. Two external quality auditors, who have ISO 9001 and JIG expertise, were interviewed to modify our initial proposed QMS. The final QMS was implemented in the into-plane fuelling services as the first phase of this implementation. Results of framework implementation are discussed in a case study. There are mutual benefits resulting from the integration of JIG and ISO 9001:2015 standards. This QMS provides a unified process for quality management practices, and enhances the effectiveness of risk evaluation as well as the opportunity for continued quality improvement. It facilitates the identifi- cation of ISO 9001:2015 requirements and establishes relationships between the roles of JIG standard and the clauses of ISO 9001:2015. The first experience from five airports as the pilot study of proposed QMS implementation minimized conflicts and duplications between JIG and ISO 9001:2015 standards, reduced the number of into-plane fuelling service incidents reported, such as oil spill, machine stoppage, re-inspections, and recall costs.
