Criteria Indicators of the Consistency of Air Traffic Controllers’ Preferences on a Set of Characteristic Errors

Abstract

Based on ICAO recommendations and statistics on aviation events and incidents during air traffic control, a spectrum of characteristic errors of n = 21 air traffic controllers was generated, which most fully and comprehensively illustrates their erroneous decisions. To establish the coefficients, a mathematical method of ranking priorities was applied. To summarize the views of m = 37 professional air traffic controllers involved in the experiment, regarding the frequency and hazards of errors identified in the ICAO scale, a multiplicative approach was implemented. It has been founded that the error’ rate indistinguishability indicator in a group system of preferences is equal \( R_{LF}^{*} = 1,23 \cdot 10^{ - 2} \), and the error’ danger indistinguishability indicator is three times worse and equal \( R_{LD}^{*} = 3,77 \cdot 10^{ - 2} \). Integrative (holistic) indicator of each error’ significance summarizes its significance coefficients in terms of frequency and hazards and is multiplicative. That allowed building the final group system of preferences. The degree of indistinguishability of the errors significance is equal \( R_{g}^{*} = 0,91 \cdot 10^{ - 2} \), which testifies to the effectiveness of the proposed approach to the implementation of ICAO recommendations regarding the frequency and the dangers of unwanted events in flight safety management.
