Abstract: We developed an analysis method of hazards related to air-traffic control (ATC). We used mixing approach procedures such as required navigation performance, authorisation required (RNP AR) and instrument landing system (ILS), as the test case. We carried out the hazard and operability (HAZOP) study and ATC real-time simulation experiments in the situation of the mixed operation for finding the hazards because we were not able to find them as the result of literature examination. We collected the data required for this analysis in the simulation experiment and selected HAZOP as the key assessment methodology. The hazard analysis method developed enables to perform a quantitative HAZOP analysis. We quantified the likelihood of accidents and the ratios between the hazard severities at the development stage. Furthermore, we discussed a safety index based on the statistics of recent catastrophic air accidents around the world. A safety index matrix showed the regions of acceptable levels with mitigation by a quantitative index value.
