Risk management in (air) transport with exemplary risk analysis based on the tolerability matrix

Transport Problems

This article is a continuation of the authors’ study on the ways to ensure safety in the Air Traffic Management (ATM) system. It directly refers to the processes of risk management involving, in particular, risk management in (air) transport. The mai aim of this paper is to present and indicate the hazard identification and risk assessment tools that can be used in air transport and to apply one of them for a risk analysis of a specific ATM originating case. This is why, after a short introduction, describing the background of the research as well as literature review, the risk management process as such is characterized. It is shown in a schematic way and its main components are identified. At the same time, from the entire management process, the risk assessment procedure is highlighted as its most crucial part. Then, general hazards identification techniques, risk analysis and assessment tools are described, with an indication that they can also be implemented in air transport, if compatible with ICAO Standards and Recommended Practices (SARPs). In the following part, the process of risk assessment in air transport, based on the Safety Management Manual, using a safety risk tolerability matrix, is characterized. Finally, in this article, an exemplary risk analysis is carried out, focusing on a selected case arising from the ATM field. For the analysed case, safety risk hazards and their possible effects are identified and then assigned to the Intolerable, Tolerable and Acceptable regions. The entire paper is summarized and conclusions are drawn in relation to the publication’s main goal. Attention is also paid to the potential causes of appearance of hazards including, first of all, lack of adequate verification procedures, as well as people’s competence and last but not the least human errors, being the reason for 70-80% of unwanted transport accidents.

The concept of risk tolerability matrix determination for aeronautical data and information chain

Journal of KONBiN

No. 43

This article is a continuation of the Authors’ study on the ways to ensure the quality and safety of aeronautical data and information in the entire process (considered as the supply chain) of those data and information creation, collection, processing and publication. In its content attention was paid to air traffic proactive safety management aa well as the need to manage identified incompatibilities. The risk assessment and tolerability matrices arising from ICAO specifications were presented, and then on their bases, the concept of such matrices determination for aeronautical data and information chain was developed. In addition, the criteria for consequences’/effects’ of incompatibilities appearance assessment related strictly to air transport were elaborated. In the summary directions for further analysis were pointed out, leading to carrying out a full risk assessment analysis of the discussed chain with the use of the FMEA method.

Artykuł stanowi kontynuację prac Autorów nad zagadnieniem sposobu zapewnienia jakości i bezpieczeństwa danych i informacji lotniczych w całym procesie (rozpatrywanym jako łańcuch dostaw) ich tworzenia, gromadzenia, przetwarzania i publikacji. W jego treści zwrócono uwagę na proaktywne zarządzanie bezpieczeństwem w ruchu lotniczym oraz konieczność zarządzania zidentyfikowanymi niezgodnościami. Przedstawiono macierze oceny i tolerancji ryzyka zawarte w specyfikacjach ICAO, a następnie na ich podstawie opracowano koncepcję wyznaczenia takich macierzy dla łańcucha danych i informacji lotniczych. Ponadto opracowano kryteria oceny konsekwencji/skutków wystąpienia niezgodności w odniesieniu bezpośrednio do transportu lotniczego. W podsumowaniu wskazano kierunki dalszych prac, prowadzących do przeprowadzenia pełnej analizy oceny ryzyka omawianego łańcucha metodą FMEA.
