Main Factor

It is substantiated that the main factor explaining the impact of "front-line" aviation operators on the interaction of ICAO flight safety concept components is their "attitude to dangerous activities or conditions". To this “attitude” is assigned a preference system based on indicators and characteristics of professional activity. Based on ICAO recommendations and statistics on accidents and serious incidents during the organization of air traffic, a spectrum of n = 21 characteristic errors of air traffic controllers was formed, which most fully and comprehensively illustrates their erroneous decisions. Focusing on the linguistic indicators of ICAO to determine the levels of frequency and danger of adverse events, it is reasonable to carry out their defuzzification by using weighted error significance factors to determine individual and group preference systems. The coefficients are determined at the fifth iteration of the application of the mathematical method of prioritization. m=37 of professional air traffic controllers were involved in the experiment. To summarize their opinions regarding the frequency and danger of errors, a multiplicative approach was implemented, in contrast to the additive approach, more accurate results are obtained. The group systems of preferences of the tested air traffic controllers were constructed in terms of the frequency and dangers of characteristic errors that do not coincide. Indistinguishability indicator was introduced. It is found that its value for the study of the frequency of errors in the group system of advantages is equal to the value  R*LF= 1,23·10-2, and for the analysis of the risks of errors - three times worse and equalR*LD= 3,77·10-2. An integrative (holistic) indicator of the significance of each error summarizes its coefficients of significance for the frequency and hazard indicators and is multiplicative. Which made it possible to build the ultimate group benefits system. The degree of indistinction of the significance of errors in it is equalR*g = 0,91·10-2, which testifies to the effectiveness of the proposed approach to the implementation of the recommendations of ICAO on the consideration in the processes of safety management of the frequency of flights and from the top of adverse events. It is proposed to use the obtained results to create a methodology for analyzing the “event tree” in flight safety management systems.

The monograph is devoted to the expert study of the dangers of typical mistakes made by air traffic controllers in their professional activities. Taking into account the influence of the human factor on flight safety and ICAO recommendations, an up-to-date list of n = 21 typical errors was formulated and the systems of preferences of air traffic controllers on their dangers were comprehensively studied. The differential method for establishing a comparable risk of errors has been substantiated and implemented, as well as the α-method (α-coefficient) for establishing the degree of coincidence of the advantages different systems, which is based on comparing the same errors not by the ranks that they occupy in different systems of advantages, but by the corresponding these ranks of nonlinear significance coefficients. The methodology for a comprehensive assessment of error threats has been substantiated and implemented, based on the qualitative (linguistic) indicators of their hazards and frequency of manifestation recommended by ICAO. The use of a multiplicative approach contributes to obtaining more reliable results that help prevent statistical errors of the I-II kind. Using the methods of the pattern recognition theory, a multi-step technology for detecting and filtering out marginal opinions has been developed and implemented, which makes it possible to build group preference systems with the required level of the opinions consistency. The development of the methodology for the application of classical decision-making criteria as strategies for building group preference systems with different levels of risk was implemented. The normalized index of indistinguishability of error hazards was introduced. The Kemeny median for nonparametric optimization of consistent group preference systems on error hazards was applied. Defuzzification of qualitative rank estimates of error hazards by providing them with the corresponding weighted significance coefficients has been carried out. The hypothesis about the possible influence of cross-cultural factors on the attitude to the dangers of errors of Ukrainian and Azerbaijani air traffic controllers was tested. The monograph is addressed to scientists and specialists who deal with the problems of the influence of the human factor on flight safety. It can be useful in the educational process of aviation operators of the "front line" (air traffic controllers and flight crew members), as well as in providing methodological content of flight safety management systems. Given the versatility of the improved and developed methods, it can also be useful for scientists and specialists who use expert technologies in their activities.

The Impact

Given the influence of the human factor on decision-making processes by aviation operators of the “leading edge”, therefore, — of the flight safety, individual and group preference systems as formalized representations of air traffic controllers about a number of spectrum ordered by danger have been investigated from n=21 of characteristic errors. That has a pronounced positive proactive character. Explicating their opinions, the air traffic controllers simultaneously form discriminating, memorizing skills, therefore, — avoidance of mistakes in a professional activity: the subjects made one third fewer errors in comparison with other air traffic controllers in the process of simulator training. Group preference systems allow identifying the features of the functioning of individual socie­ties — dispatch shifts, possible group deformations, as well as the impact on their members of the presentation features of the performing technological procedures specifics by instructors. m=37 individual preference systems of the air traffic controllers, which were involved in research, were built by pairwise comparison of the danger of errors and the application of a differential method of distributing the indicator of their total danger. That contributed to conducting of 420 pairwise error hazard comparisons. The implementation of a multi-step procedure for identifying and screening out 10 marginal opinions has led to a statistically consistent group system of preferences: Kendall’s concordance coefficient equals is W=0,700 and it became statistically significant at a high level of significance of a = 1 %. The decision matrix was formed from mА=27 individual preference systems of the air traffic controllers, which, by the definition, is a “cost matrix” and for the solution of which a methodology for the correct application of the classical decision criteria by Wald, Savage, Bayes-Laplace, Hurwitz has been implemented. It revealed the identity of the group systems of preferences obtained by Wald and Savage criterion, as well as the Bayes-Laplace criterion and such a strategy of group decisions as summation and averaging of ranks. The empirical preferences are generally the same: Spearman’s rank correlation coefficients are unusually high (RB–L–W/S=0,8922, RB–L–HW=0,9263, RW/S–HW=0,9477) and statistically gullible at a high level of significance for human factor studies . The following values of the normative indicator of the not distinguishing dangers of error risk in the group preference systems are obtained: R*BL=0 , R*HW=0,19·10-2, R*W/S=5,58·10-2. The value of this indicator for the group is R*g=0,52·10-2.

The negative and persistent impact of the human factor on the statistics of aviation accidents and serious incidents makes proactive studies of the attitude of “front line” aviation operators (air traffic controllers, flight crewmembers) to dangerous actions or professional conditions as a key component of the current paradigm of ICAO safety concept. This “attitude” is determined through the indicators of the influence of the human factor on decision-making, which also include the systems of preferences of air traffic controllers on the indicators and characteristics of professional activity, illustrating both the individual perception of potential risks and dangers, and the peculiarities of generalized group thinking that have developed in a particular society. Preference systems are an ordered (ranked) series of n = 21 errors: from the most dangerous to the least dangerous and characterize only the danger preference of one error over another. The degree of this preference is determined only by the difference in the ranks of the errors and does not answer the question of how much time one error is more dangerous in relation to another. The differential method for identifying the comparative danger of errors, as well as the multistep technology for identifying and filtering out marginal opinions were applied. From the initial sample of m = 37 professional air traffic controllers, two subgroups mB=20 and mG=7 people were identified with statisti-cally significant at a high level of significance within the group consistency of opinions a = 1%. Nonpara-metric optimization of the corresponding group preference systems resulted in Kemeny’s medians, in which the related (middle) ranks were missing. Based on these medians, weighted coefficients of error hazards were determined by the mathematical prioritization method. It is substantiated that with the ac-cepted accuracy of calculations, the results obtained at the second iteration of this method are more ac-ceptable. The values of the error hazard coefficients, together with their ranks established in the preference systems, allow a more complete quantitative and qualitative analysis of the attitude of both individual air traffic controllers and their professional groups to hazardous actions or conditions.

The Impact

A human-in-the-loop simulation was conducted to evaluate the impact of Unmanned Aircraft Systems (UAS) with low size, weight, and power (SWaP) sensors operating in a busy, low-altitude sector. Use of low SWaP sensors allow for UAS to perform detect-and-avoid (DAA) maneuvers against non-transponding traffic in the sector. Depending upon the detection range of the low SWaP sensor, the UAS pilot may or may not have time to coordinate with air traffic controllers (ATCos) prior to performing the DAA maneuver. ATCo’s sector performance and subjective ratings of acceptability were obtained in four conditions that varied in UAS-ATCo coordination (all or none) prior to the DAA maneuver and workload (higher or lower). For performance, ATCos committed more losses of separation in high than low workload conditions. They also had to make more flight plan changes to manage the UAS when the UAS pilot did not coordinate DAA maneuvers compared to when they did coordinate the maneuvers prior to execution. Although the ATCos found the DAA procedures used by the UAS in the study to be acceptable, most preferred the UAS pilot to coordinate their DAA maneuvers with ATCos prior to executing them.

The article analyzes the existing problems that impede the effective safety management of the flights of the air forces of the Armed Forces of the Russian Federation. As a result, this analysis revealed the contradiction between the need to build a safety management system and the lack of effective mechanisms for assessing the state of the aviation system and taking into account the influence of the human factor of aviation professionals on flight safety. The contradiction identified the need for developing a set of methods to estimate the actual state of the aviation system protection from the effects of threats associated with the human factor of flight personnel. A methodological apparatus was developed for assessing the security status of an aviation system against hazardous factors, which is based on applying a personality-oriented approach to assessing and managing the state of an aviation system. The method of assessing the state of flight safety allows you to quantify the state of protection of the crew-aircraft system from the impact of hazards caused by the personal factor of a particular pilot before the flight and to assess in near real-time the state of protection of the crew-aircraft system during the flight. The method of assessing the state of safety in aviation formation allows you to assess the status of safety during the organization and conduct of flights, taking into account the influence of the human factor of flight personnel in  near real time.

Abstract In the field of security in transport distinguish risks related to flight safety and aviation security. Safety of flights is ensured through the reliability of aviation equipment and the qualification of the personnel who services and operates it, aviation security is a condition of protection from illegal interference in its activity. Risk management in civil aviation in the field of security is a relatively new direction of activity. Deep research in this area began only at the beginning of the XXI century. It is quite difficult to use the existing experience of risk management, accumulated in other spheres, as civil aviation has significant features. Various methods and schemes can be used to assess risks. The article discusses various options for predicting risks using the “event tree” and “risk factor tree” methods.

Core Issue

The management of safety critical operations cannot be left to the initiative of those individuals directly in contact with the production processes. Society as a whole has a role. This paper explores the interface between societal components having a direct active role in the “safety debate”. The reference domain is air traffic management and the interface is among air traffic controllers and pilots – as directly involved in the management of the air traffic – and two agencies, the NTSB (responsible for safety investigation after an accident) and FAA (responsible for regulating, upgrading and training of the workforce). Recent debates in safety management highlight that safe practice is a control problem: the result of effective hierarchical transmissions of safety constraints and making the boundaries of acceptable performance visible. This work analyzes how safety constraints related to an alarm system are represented, transmitted and interpreted by several parties – all committed to safety of operations in air traffic management. A “miscalibration” pattern has emerged where the tendency to ignore the alarm was initially addressed at higher hierarchical levels in relation to alarm design, and only in 2006 was addressed in relation to the core issue of nuisance or false alerts (FA).

The Impact

In air traffic management, a fundamental decision with large cost implications is the planning of future capacity provision. Here, capacity refers to the available man-hours of air traffic controllers to monitor traffic. Airspace can be partitioned in various ways into a collection of sectors, and each sector has a fixed maximum number of flights that may enter within a given time period. Each sector also requires a fixed number of man-hours to be operated; we refer to them as sector-hours. Capacity planning usually takes place a long time ahead of the day of operation to ensure that sufficiently many air traffic controllers are available to manage the flow of aircrafts. However, at the time of planning, there is considerable uncertainty regarding the number and spatiotemporal distribution of nonscheduled flights and capacity provision, the former mainly due to business aviation, and the latter usually stemming from the impact of weather, military use of airspaces, etc. Once the capacity decision has been made (in terms of committing to a budget of sector-hours per airspace to represent long-term staff scheduling), on the day of operation, we can influence traffic by enforcing rerouting and tactical delays. Furthermore, we can modify which sectors to open at a given time (the so-called sector-opening scheme) subject to the fixed capacity budgets in each airspace. The fundamental trade-off is between reducing the capacity provision cost at the expense of potentially increasing displacement cost arising from rerouting or delays. To tackle this, we propose a scalable decomposition approach that exploits the structure of the problem and can take traffic and capacity provision uncertainty into account by working with a large number of traffic scenarios. We propose several decision policies based on the resulting pool of solutions and test them numerically using real-world data.
