Authorities in civil aviation and other high-risk industries are currently making a progressive shift from compliance-based to performance-based oversight. This entails many challenges where among the foundational ones lies the issue of establishing effective performance-based checklists to be used when auditing organizations. This paper addresses the issue with a systemic approach to safety, namely the System-Theoretic Accident Model and Processes, which treats safety differently from its predecessors. The model is used to infer performance-based audit questions for selected type of aviation organization based on regulatory requirements, thus extending the compliance-based approach by broader reasoning about safety issues. The questions were tested with the Civil Aviation Authority during real-scale audit and the conclusions show that this is a promising approach to reduce the currently used subjective approach to evaluation of the actual performance, with many practical benefits for the Authority.

Maintenance, Repair, and Overhaul (MRO) organizations are one of the pillars of aviation safety. They ensure the airworthiness of aircraft in accordance with regulatory requirements. In Europe, until the recent changes in legislation, safety was part of quality and compliance management. Today, MROs are required to implement a Safety Management System (SMS). The paper focuses on MRO hazard and risk register, proposing a sample register with a procedure how to develop it. The proposed solution integrates with other parts of the integrated management system, such as quality control or occupational health and safety. The hazard and risk register was proposed using the recent approach of the System-Theoretic Accident Model and Processes (STAMP) accident causality model, suitable for complex sociotechnical systems, which are typical in the aviation today. The proposed solution allows the assessment of the system as a whole, which leads to the identification of new types of hazards and structuring of the existing ones. The presented study was performed with two European MROs to evaluate and validate its outputs.

The aim of this paper is to propose a structured approach to define the occurrence reporting form in an international airline. For this purpose, the System-Theoretic Process Analysis (STPA) was used. The method serves for analyzing the flight operations of the air carrier and subsequently for the prediction of causal factors relevant for the operations. The result is a sample reporting form for events during taxiing and take-off, which are subject to mandatory reporting under the European legislation. The form was tested by commercial aircraft pilots. The obtained data were analyzed, evaluated and placed in the context of operating conditions. Based on the results obtained, it can be said that the proposed reporting forms provide safety department staff with enhanced insight into reported occurrences and can be used to apply targeted safety measures.

Flight procedures are one of the main pillars for the safe performance of a flight. However, sometimes flight procedures must be modified. The need to modify them may arise from operational experience or a safety study. One of the methods that can be used to perform a safety study for the purpose is System-Theoretic Process Analysis (STPA). The goal of this paper was to perform a safety assessment of the Cessna 172 flight procedures based on a proactive systems approach to safety, using STPA. The goal was to identify potential safety issues related to selected flight procedures and to propose corrective measures or safety recommendations that could be used in practice. The results show how to work with STPA in the context of flight procedures and what measures or recommendations emerged from the analysis for the Cessna 172 flight procedures. The analysis confirmed the possibility of using system safety approach in general aviation to assess flight procedures and usefulness of its results.

Aviation safety taxonomies are the sets of terms on which occurrence reporting systems are based today. Since occurrences in aviation are one of the main sources for aviation safety, taxonomies are used to capture as much detail as possible from an occurrence. On the basis of taxonomies, overviews are regularly created for certain periods. Currently, a systemic approach to safety is increasingly being applied in the domain. The System-Theoretic Accident Model and Processes (STAMP) is one of the systemic safety models that can analyze and investigate complex systems. However, with its introduction into full operation, major changes could arise. One such change would certainly be focused on the currently used aviation safety taxonomies, such as the European Co-ordination Centre for Accident and Incident Reporting Systems (ECCAIRS). In this respect, the goal of this paper is to propose an alignment of the ECCAIRS taxonomy with STAMP, with a focus on event types. The methodology, together with the results, detail the alignment design and validation. The resulting proposal shows how the ECCAIRS taxonomy could support STAMP-based occurrence data processing and, at the same time, it brings new insights that could help to structure the taxonomy in the future.

Aircraft maintenance at the technical base includes both scheduled and unscheduled repairs. When performing repairs, there are detailed inspections of aircraft, which are ordered in advance by the customer. During these inspections, it is possible to detect other unsatisfactory condition of the aircraft in terms of continuing airworthiness, which needs to be corrected. These unplanned failures are findings and are entered into the maintenance organization's system, which is required to keep records of activities performed on the aircraft. Finding descriptions are created by technicians and are usually stored as unstructured text that does not allow subsequent analysis with a database of such records. The presented work performs automatic text analysis of findings using a dedicated software tool. For the purpose of the analysis, a lexicon was created, with components and failures appearing in maintenance records. The lexicon was used in automatic text analysis, where the output was a statistic of the most frequent components and failures in the stored maintenance data. This statistic can be used for maintenance planning optimization and better prediction of unscheduled repairs.

Global air transport was experiencing a steady growth for decades despite various economic or political crises. However, the worldwide spread of Covid-19 and its associated travel restrictions led to an unprecedented 60 % drop in global air traffic volume according to the International Civil Aviation Organization (ICAO). This has had a dramatic impact on airline companies and their pilots who were suddenly unable to practice their profession. In order to return to service, they had to go through a simulator scenario aimed at restoring crucial pilot competencies. The following paper describes an experiment conducted with the goal to verify whether a simulator scenario proposed by IATA and adopted by airline companies can restore such competencies. The tailored experiment scenario involved specific flight maneuvers and precision approaches together with theoretical knowledge test. It was completed on a flight simulator with 34 pilots holding a valid type rating for Boeing 737NG. One of the results of the experiment show that the accuracy of a pilot's manual flight may not always correspond with the workload they are subjectively experiencing.

Evaluation of safety performance remains central to any safety and risk management. Currently, there are very few support tools and methods which allow for quantitative approach in this domain. One of the successful methods available to this end is the Aerospace Performance Factor (APF). The method is based on hierarchical clustering of taxonomy-based safety performance indicators, using simple and intelligible formula to compute the overall safety performance signal. The work presented in this study deals with one of the APF shortcomings, namely the absence of nonlinear relations among the performance indicators to capture more accurately the risk in the assessed system. It proposes an addition of new decision criteria behind the APF method as part of the application of Analytical Hierarchy Process (AHP), namely the impact of respective performance indicator on other indicators, regardless of their hierarchical structure. This addition leads to relative changes of performance indicators significance, where those with the highest potential for nonlinear interactions among the entire set of performance indicators are emphasized and the change in their weight ultimately leads to changes in the overall APF signal. The study results indicate that the extended APF signal is refined in terms of extremes and it draws more accurate picture about the actual safety performance, eventually supporting better identification of deviations from its acceptable values. The study was experimentally carried out in the aviation with data from the European Central Repository (ECR) originating from United Kingdom during the years 2013–2015 and verified further on data sets from Finland and Denmark.

Tato zpráva pojednává o znalostních systémech v rámci hodnocení spolehlivosti a kvality letadlových systémů a komponent. Pod znalostním systémem se v praxi rozumí softwarový systém, který dokáže pracovat se znalostí a tu nabízet uživateli jako podporu v rámci jeho pracovních postupů, nebo jí přímo používat v automatizovaných procesech, kde znalostní systém simuluje rozhodování prováděné experty. Znalost se v počítačové terminologii považuje za nejvyšší formu organizace strukturovaných dat, která je daná prvky, jejich vlastnostmi a relacemi, popřípadě operacemi, které lze nad danými prvky vykonat. Vzniká zpracováním dat a informací, v rámci znalostních systémů se obvykle vyjadřuje explicitně a pro její tvorbu a uchování se využívá technologie ontologického inženýrství. Je nezbytná pro optimální rozhodování se v rámci řešení problémů.

To conduct reliability studies, Fault-Tree Analysis (FTA) and Failure Mode and Effect Analysis (FMEA) are among the most used methods. However, with the emergence of software and complex modern systems, such analyses are not sufficient anymore. Therefore, System-Theoretic Process Analysis (STPA) was created to solve such problems and conduct safety analyses but was never used for a reliability analysis. This paper presents a reliability study of the Wheel Braking System (WBS) of the Cessna Citation Mustang using STPA, and a comparison study using FMEA. Outputs of both methodologies were compared and showed that STPA produces better results.

Maintenance, Repair, and Overhaul (MRO) is one of the basic pillars of aviation. Continuing airworthiness involves a lot of maintenance staff that works on-site and MRO management has to take care of their workplace safety. The number of hazards in the maintenance workplace is high; mechanics can find a list of warnings and precautions in manuals and other documents to maintain the aircraft. Using maintenance manuals and investigation data, workplace safety specialists prepare tailored workplace safety requirements for each maintenance task. Workplace safety in MRO is a complex problem, yet the current requirements are based on linear causality. Their output is thus limited and cannot fully ensure workplace safety in MRO. Some studies describe workplace safety using a systemic approach to safety, however, none was focused on the MRO field. In our research, we applied a systemic approach to workplace safety in MRO. We used the System-Theoretic Process Analysis (STPA) and prepared a list of systemic requirements for MRO organization. The list was validated in real aviation organizations with the conclusion that it can help cover more safety issues and ensure a higher level of workplace safety in the MRO than the current approach.

Simulation technologies have significantly evolved in recent years. Devices providing high fidelity simulation are becoming widely available in many sectors. In transportation, simulators have proven successful in personnel training, modeling nonstandard situations and even in development and research. The primary use of simulation is still focused on educational purposes. The simulated environment provides grounds for monitoring and assessment of trainees' behavior. However, in addition to simulation technologies, other tools must be deployed. These tools record the physiological functions of the trainee and assess psychophysiological conditions. Specific events, such as a stressful situation, can be detected. Similar scientific-related activities may also lead to assessment of perception. This is a complex problem for both evaluation and data collection. Additionally, it puts specific demands on experimental equipment. The presented article describes the development of a flight simulation device that enables the evaluation of the pilots' perception. This solution is based on X-Plane flight simulation engine with virtual reality (VR) and employs eye-tracking, brain activity monitors and heart activity monitors. The cockpit has a modular design and can be adapted to several aircraft types. VR-Gloves are used to interact with actual aircraft controls such as control yoke, thrust levers and even overhead panel switches. This setup creates a real-feel concept when controlling the aircraft. The presented solution is a technology demonstrator and is being tested with aviation training scenarios.

Cílem projektu bylo vytvoření konceptu měření, analýzy a vyhodnocení psychofyziologické kondice pilotů jako potenciálního indikátoru selhání v závěrečné fázi přiblížení a přistání na letišti, s hlavním ohledem na analýzu variability srdečního rytmu, kvantifikaci EEG a modelování vizuální percepce. Koncept cílil na zvyšování bezpečnosti letecké dopravy tím, že umožní vyhodnocení psychofyziologické kondice a kognitivních schopností posádky ve fázi letu, která patří mezi nejrizikovější a nejvíce náchylné na nedostatky leteckého personálu. Dosažení konceptu umožní další zlepšování úrovně provozní bezpečnosti v letectví pomocí snížení rizika souvisejícího s jednotlivými úkony při přistání na letišti. Pro tyto účely byl vytvořen simulátor, který je schopen prostřednictvím virtuální reality simulovat let se společným sledováním pohybu očí ve scéně a sběr fyziologických dat. Výzkumná zpráva ukazuje na aktivity spojené s realizací tohoto zařízení, předzpracování zaznamenaných dat/signálů, jejich význam, způsob interpretace těchto dat a v neposlední řadě nastavení experimentálních měření a jejich evaluaci. Projekt probíhal od 06/2019 do 05/2021. V rámci řešení projektu vzhledem k pandemii Covid-19 neměl řešitelský tým kontinuální přístup na pracoviště a nebylo tak možné realizovat některé aktivity v plném, zamýšleném rozsahu. Tato situace trvala od 03/2020 do 03/2021 a dopadla především na měření zahrnující lidské subjekty, jejichž realizace nebyla možná vůbec nebo za velmi omezených podmínek. I přes uvedené problémy, vynaložil řešitelský tým značné úsilí pro úspěšné ukončení projektu a splnění všech závazků s ním spojených.

The Safety Data Collection and Processing System (SDCPS) at aviation authorities is an important component for maintaining flight safety. Aviation safety occurrences are often the result of several deficiencies in the system, which brings the need to examine the system as a socio-technical whole. The System-Theoretic Accident Model and Processes (STAMP) is one of the systemic safety prediction models that deals with socio-technical systems and offers a possible solution for new approach to the safety data collection and processing. This paper focuses on the use of STAMP for SDCPS at aviation authorities. The methodology in this paper is based on the use of Business Process Modeling Notation (BPMN) tool for graphical algorithmic representation of processes according to the theory. This approach provides a systemic platform for proposal of safety data collection and processing. The resulting proposal to be used with SDCPS shows how to use the systemic approach of STAMP within current SDCPS systems and compares it with the current practices and standards in the aviation.

This study was aimed to find a way how to deal with hardly predictable circumstances while performing routine access works during aircraft heavy maintenance and to estimate the time spent with the work. The lack of maintenance data was crucial in dealing with this issue, therefore, additional measurements were necessary. For this purpose, this study was done in cooperation with Czech Airlines Technics Maintenance Repair Organization. The company currently estimates timing of panel manipulation based on the information contained in the manufacturer’s documentation. A database was established with work measurements of maintenance technicians accessing panels during real aircraft maintenance. They should by their nature reflect complications arising during the access panel manipulation and of the specific operational factors in the company. The main importance of the database lies in the creation of additional data to refine the aircraft maintenance planning estimates. Based on the measurements, it was possible to demonstrate that the access panel manipulation times as stated in the manufacturer’s documentation are only indicative. For each measurement performed, the measured overall time of panel manipulation was much higher than the equivalent time estimates by the manufacturer. During the measurements, several other factors were also discovered as causal to differences in the manipulation times. The database served as the basis for a developed software tool providing more accurate estimates of access panel manipulation times and resulting in more accurate estimates in maintenance planning in the Czech Airlines Technics, although the results are well reusable with other Maintenance Repair Organizations.

The aim of this work is evaluation of the process of airport passenger and cabin luggage security check, using methods originally dedicated to safety engineering. The evaluation is based on the Functional Resonance Analysis Method (FRAM) and the applied computation of the model follows existing research on FRAM. Variability for each security check function in terms of time and precision is defined, considering also the external conditions affecting the system. Next, an application is developed, which represents the interface between the FRAM-based calculations and the user. The main goal of the application is evaluation of security check according to the provided measurement inputs and provision of practical representation of the results to the industry experts. The results indicate that FRAM can be used for the purpose of modeling security systems and that the modeling results can help industry experts to identify their weak points, together with suggestions how they could be improved.

The present study aimed to evaluate the characteristic influence of physical therapeutic procedures of vacuum-compression therapy (VCT) on microvascular perfusion (MiP) and macrovascular perfusion (MaP) of the lower limb in diabetic patients. A sample of nine patients with a medical history of type 2 diabetes was used for the purpose of this study. Most of the subjects' medical conditions included venous and neurological complications of the lower limb, whereas the rest of the subjects entered the treatment due to injury recovery or their phlebological disease. The PeriFlux System 5000 (Perimed, Sweden) diagnostic device was used to measure MiP. The MaP was evaluated based on the perfusion index (PI) using the Extremiter monitoring device (Embitron, Czech Republic) designed to perform VCT procedures. The study found that MiP and MaP increase as an effect of VCT procedures and at the same time PI clearly reflects the effect of the applied vacuum and compression phases, verifying the method's vital influence on peripheral perfusion disorders.

This article focuses on identifying limitations and deficiencies of reliability methods that are currently used in the aviation industry. The goal is to propose a solution to address these issues and, consequently, improve the way reliability analyses are carried in the industry. In collaboration with an aircraft engine manufacturer, Failure Mode and Effects Analysis (FMEA) of an aircraft engine lubrication system was carried the traditional way and with current tools used by the company. Reliability ontology suitable to carry the analysis in semi-automatic way was then proposed, implemented, and used with the same FMEA analysis. The results show that the ontology-based approach has significant potential for improving the consistency and overall quality of the reliability analyses in the aviation. This article details the process of development of an FMEA ontology model, case study of its application and the comparison of the traditional and the ontology-based approach.

During their professional career, pilots often experience a change in workplace conditions in the form of an aircraft cockpit ergonomics change. Change of working conditions may impact their perception of flight data or the pilot's psychophysiological condition, especially in cases of inexperienced pilots. The presented study deals with the influence of cockpit ergonomics change on the performance and pilot workload during a training course. We divided 20 subjects with no previous practical flying experience into two training groups (Gr. A and Gr. B). The flight training was focused on acquisition of basic piloting skills where both groups experienced cockpit ergonomics change in different training phases. The performance (piloting precision) was assessed based on deviations from predetermined parameters of the monitored flight manoeuvres. Heart rate variability qualified the extent of workload. The study showed the influence of the cockpit arrangement on piloting precision, where the transition to other type of cockpit ergonomics did not influence pilots' subjective workload with statistical significance.

This paper deals with the operational issues of aircraft components and their reliability, from the perspective of the aircraft operators. Modern airliners are equipped with advanced ways of data collection of most flight and technical parameters that can be used to optimize their operations. This study deals with the pneumatic system (ATA36 chapter) of the B737NG aircraft that is susceptible to failures in the operations, leading to the aircraft becoming unserviceable for periods of time. A novel approach is proposed to analyze the system behavior by its modeling by means of the Unified Modeling Language (UML) and Fault-tree analysis, using real operational data. Next, this paper proposes simple operational measures than can avoid the aircraft on ground (AOG) states and decrease unexpected expenses due to the system failure. The results show that this new approach is very practical and can have significant effect on the airline operations, largely reducing extra costs and flight delays and allowing for better planning of aircraft maintenace.

The following paper is focused on safety data collection and processing in the Maintenance, Repair and Overhaul (MRO) organizations. The goal was to propose a way how to collect and process details of safety data using a total systems safety approach. The problem of details of safety data processing worries most of the companies, because there are unique information in it. For the safety analysis processes, one of the key steps was to choose a safety model. The Systems-Theoretic Accident Model and Process (STAMP) systemic safety model was chosen for the purpose. According to the results from the previous research, MRO processes were modeled using Business Process Model and Notation (BPMN). The resulting process model was extended by information needed for STAMP-based analyses. The result is a workflow proposal with several technical details that show how safety data collection and processing can be changed using STAMP. The proposed solution was successfully validated with Czech Airlines Technics a.s. and considered useful base for further development of MRO safety management systems.

Safety management belongs to the newest and one of the fastest developing domains in the aviation. Since its invention from around the year 2000, there has been growing interest worldwide in getting more control over the negative aspects of risk in flight operations. Today, the achievement is remarkable given the safety records of modern aviation. However, past success cannot be guarantee of future safety due to fast pace of development and ever-increasing complexity of the aviation industry. Past methods and approaches do not indicate as great performance today and so has the approach to safety management deal with the new emerging challenges. This paper deals with potential implementation of the modern safety theory into the established framework of safety management system. It utilizes allcurrent safety models and methods and proposes how the framework could be updated in the aviation to achieve new generation of safety management. The results show how the theory can be integrated in the aviation with some remarks about the new concept. The paper shows the way forward to the future safety management and ground the future research in the domain.

Due to current technological growth, the safety management system has evolved with complex systems. Complex causes of accidents often exceed the designation of traditional safety assessment techniques. One of the problems is the difficulty of examining all possible scenarios that may occur when combining system components, especially software products and people. In response to this problem, the paper presents conclusions from the implementation of the control structure in the field of civil aviation safety. The control structure model helps to identify hazards that may occur during processes on RWY. Further, the paper provides an evaluation of control structure changes by risk assessment and by mitigation potential of hazard. Using the mitigating potential of hazard verified that the changes have contributed to improving safety and Commission Regulation No. 139/2014 is met.

Modern airlines strive to satisfy customer requirements to the highest extent possible, continuously searching for advantages of modern technologies that could be used for the purpose. Another motivation may be the willingness to improve overall operations effectiveness while possibly reducing costs of each flight. In this regard, WiFi modification and cabin reconfiguration are common tasks in today aviation world. These are one of the typical examples of the current aircraft upgrades demanded by airlines to better meet customer requirements but from the perspective of a maintenance organization, this is often a challenging task. With respect to that, this article describes how turnaround time of cabin and WiFi modification can be improved during base maintenance visits in MROs, the Maintenance Repair and Overhaul organizations. This improvement was verified with the Czech Airlines Technics, one of the famous MROs in Europe. The main points of success are correct understanding of human factors, implementation of maintenance planning, Gantt charts and also application of modern approach to workflow in the MRO itself. Once implemented, turnaround time of these complex maintenance visits can be shortened by days. The airliners highly appreciate this fact and it also enables the MRO to achieve more hangar space during maintenance season.

This article focuses on the issues related to hazard identification and risk evaluation in the safety studies. Specifically, the purpose of the paper is to describe reasons of deviation based assessment used in the new methodology developed by the Czech Technical University in Prague, in cooperation with Prague Airport. The methodology incorporates current safety management approach and modern safety theory principles. The main change is the modification of selected safety assessment processes, which are now based on the Systems-Theoretic Accident Model and Processes (STAMP) model theory. Practically speaking, the key steps of System-Theoretic Process Analysis that are based on the STAMP, were implemented. This article discusses the benefits of shifting attention to a more detailed look into the system, specifically into individual process steps. In these steps deviations are derived from the respective activities, i.e. a deviation from the expected behavior of the controlled system is observed. Monitoring and managing these deviations brings certain benefits for safety management.

The goal of this article is to create nomenclature for safety events classification, which will help to identify the root cause of such events via STAMP model. The thesis is made with help of the GEAC company, which provided necessary data or realization of this classification. STAMP model of the company is divided into individual system analyses. The nomenclature of primary factors, which may lead to occurrence of the event, is then implemented into the real and fictive event sample. The proposed nomenclature and system analyses are intended to be used for future database development in GEAC as well as in any other company, that is interested in such safety event classification.

Maintenance planning and calculation of maintenance turnaround time require consideration of many influences. This leads to the calculated turnaround time usually not being precise. This paper deals with the time estimation of unscheduled works which may occur during maintenance of an aircraft and which can lead to financial losses or reduced usability of the aircraft for flying missions due to extended stay in a hangar bay. The main assumption is that there exists dependence between unscheduled works and predictors known prior to the maintenance. Two methods were considered to estimate the turnaround time, namely maximum likelihood estimation and Bayesian regression. The study was done in cooperation with Czech Airlines Technics company which provided necessary data from aircraft maintenance. The results indicate that, given the data normally available, only the model based on maximum likelihood estimation managed to reproduce reality when proposed for each aircraft type individually. The model was validated in the Czech Airlines Technics company and implemented into software environment.

Presented article focuses on support and creating of supporting indicators for Evidence-Based Training, Specific orientation lays on assessment of pilot’s performance and heart rate assessment that may indicate psychophysiological condition of pilot. Method of experimental measurements included two groups (Gr. A and Gr. B) of ten subjects that completed simulator training and flight training on real airplane. Influencing factor for transition from analogue to glass cockpit layout was implemented for both groups where one group completed preparation for the transition (Gr. B) and the other did not (Gr. A). Results demonstrate that precision of piloting technique during final phase of training raised within Gr. B compare to Gr. A, however, rANOVA tests revealed that mean heart rate was almost same for both groups across the training phases. In addition to these facts, significant correlation was detected between subjective and exact assessment of pilot precision which together with other presented results represents the fact that pilot performance assessment could be done mainly by monitoring of pilot precision and correctness of performed lessons and manoeuvres. Presented research brings another possibilities for development of pilot training as well as to data-driven training.

The issue of security processes in the transport of air mail consists, above all, of the consignor's ignorance of prohibited articles in air mail. Shipments received for national postal traffic have different criteria as to what may be their content. Much stricter rules apply to air transport. Postal operators have not yet taken any measures to cover the different rules for ensuring the safety of consignments that are carried by air. By comparing the process of receiving shipments to air traffic between postal operators, shippers, and cargo agents, we were able to propose measures to accommodate differences in mail acceptance. Suggestion of measures to the issue should eliminate the risk of inserting prohibited and dangerous items into the consignment.

This study presents the issue of fatigue and its quantification by the means of psychophysiological indicators. For the purpose of the study, 24 hours experiment was proposed consisting of eight about an hour long simulated IFR flights. Eight students of the Department of Air Transport, Faculty of Transportation Sciences, Czech Technical University in Prague participated in the study, all with comparable theoretical and practical skills. During individual flights, ECG curve was recorded as a heart activity signal. From the ECG signal, individual RR intervals were extracted and subsequently an analysis in three areas was performed: time and frequency analysis and analysis by the means of Pointcaré plot. The acquired data were statistically evaluated and compared. Based on Friedman ANOVA and subsequent post-hoc analysis, statistically significant differences between first and sixth measurement were identified, which corresponded to the circadian low. It is also possible to claim that Pointcaré plot appears as a suitable means for fatigue quantification.

In the age of data, enterprise-related data can be efficiently used for supporting safety management decisions. In this paper, the state of the art in the domain of aviation safety is reviewed and problems that current aviation safety information systems suffer from are identified. Based on the outcomes, ontologies are defended as a technology for safety data management and the design and implementation of an ontology-based information system for aviation safety data integration is presented. The system was developed in cooperation with the Civil Aviation Authority of the Czech Republic, and it is described in terms of design, core technologies, and achieved functionalities. Subsequently, it is compared to other available solutions in the domain. The results indicate that by linking the features to ontologies, many desired characteristics of the safety information system were achieved due to proper utilization of top-level ontologies and that the solution offers a systematic and sustainable way for improving aviation safety.

This paper introduces a vector approach extension of basic and popular concept for risk evaluation tool - risk matrix. Due to the development of new risk analysis methods, it is appropriate to consider upgrades or extensions of the existing risk evaluation methods. Inspiration for the extension can be Failure Modes and Effect Analysis (FMEA). FMEA is a well-established method for safety and reliability improvement in various industries. A Risk Priority Number (RPN) is used by the method to evaluate risk and determine a failure mode priority in FMEA. However, RPN is not a sufficient tool for risk evaluation of the process deviations but it can be an inspiration for the extensions of risk matrix detectability. The extension requires a change in the evaluation and in the presentation of the results. Application of the vector display during the RPN evaluation process can be useful for the method accuracy and for the presentation of the results.

In this paper, we introduce a new concept of improved safety data management, with the focus on data collected on a daily bases in the aviation industry. The given concept is developed as a component of the wider airport safety data management system, dealing with data from continuous process monitoring or performed audits. Availability of airport safety data enabled a development of the concept within airport environment that respects all relevant particularities typical for airport operations. Because of slight differences between various aviation industry organizations, the final solution is supposed to be tailored according to given conditions and needs of individual organizations. However, general concept represents a common starting foundation applicable without a need for extensive concept modification. Here, we aim to discuss the compatibility and internal implementation of such component into a previously developed safety data management system. It also takes into consideration an impact on daily operation performance, influenced by a change in the proposed system.

Ever-changing situation in the aviation demands a change in flight training programs that would reflect present needs and threats in contrary to the traditional training that didn’t changed much for decades. Therefore, new alternative training concepts have been developed that cover these needs. However, these concepts do not apply to initial training which seem to be a crucial phase of a pilot training. Thus, the aim was to create a software solution that would identify individual flight maneuvers and evaluate them so that the overall evaluation would be done by considering objective evaluation and flight instructors’ subjective expertise. A study was done with strictly given flight schedules. For the purpose of automatic maneuver detection, density-based spatial clustering of applications with noise – DBSCAN clustering algorithm was used, which could determine maneuvers and thus exclude the noise from clusters of maneuvers. The results indicate that the proposed solution was able to identify the prescribed maneuvers with high sensitivity. The solution could be extended in the future to identify all flight maneuvers considering as many parameters from flight data recorder as possible and thus carry out complete objectively based pilot performance evaluation.

This paper deals with safety performance predictions in the aviation, which address the long-term global efforts to achieve predictive risk management by the year 2028. Predictive risk management regards timely and accurate detection of risk, well before some incident or accident takes place so that effective control actions can be provided. To assure achieving such diagnosis, it is necessary that mathematically well-founded predictions will become part of existing safety management systems with the capability to predict key performance indicators. From current safety metrics and with respect to the data available in the aviation, overall safety performance was selected as suitable candidate for predictions. To obtain the performance signal, Aerospace Performance Factor methodology was utilized. Due to confidentiality restrictions with regard to aviation safety data, this study relies on public data sets from the domain of European Air Traffic Management. Dedicated resampling method was used to fill in the gaps of real data sets by transforming expert knowledge into mathematical functions. This enabled the possibility to build and test mathematical models for predicting safety performance. Because the identified data sources included some data, which are not necessary for computing safety performance but relevant in its context, conditional forecasts were made possible. With respect to this, the goal of this paper was to research and evaluate possibilities for both conditional and unconditional forecasts in the context of future risk management. Time-series analysis of the computed safety performance was conducted using ordinary least squares and maximum likelihood estimation. Each of the methodology led to different mathematical model and different predictions. Specific aspects of each methodology were identified.

At present, the concept of reaction time measurement is used as one of the methods of psychological testing. Its usage spectrum, however, covers rehabilitation medicine, neurosciences and similar. Available systems used to measure reaction time deal with complex reaction time, i.e. the time between generating the stimuli and respective reaction via effector. Typical limitation is the design of these devices, which usually fits specific application, but it is not reusable for other applications. The goal of this paper is to introduce concept of device measuring reaction time of both upper and lower limbs, to visual or acoustic stimuli. Design of the device allows for application independence, i.e. it is reusable for wide range of different applications. This independence is supported by open software platform, including base set of testing tasks. In case of measurement of upper limb reaction time, the device allows measurement of individual components of the reaction time, opening new capabilities for deeper understanding of human sensory systems with respect to the speed of reaction to external stimuli.

Aviation safety data are limited in availability due to their confidential nature. Some aggregated overviews already exist but in order to effectively use the data, it is important to fill the gaps of their existing limitations. For some data, there are not enough data points in order to process them through advanced analysis. For other, only expert assumptions can be obtained. In both cases, these shortcomings can be addressed via proper data resampling or simulation where little effort can make the data suitable for various research and development initiatives. Examples of real aviation safety data made public are demonstrated together with key principles of how to perform their resampling. Then, for cases where only expert assumptions are available, general solution to the transformation of the assumptions into simulated data is introduced. The goal is to demonstrate how to transform accessible data or knowledge about aviation safety into data samples with sufficient granularity. The results provide general solution suitable not only for aviation safety data and knowledge, but also for similar transportation or high-risk industries related data issues, indicating that both the data resampling and simulation provide an option for generating datasets, which can be used for statistical inferential methods, linear regression modelling, recurrent analysis etc. Example of data resampling application is included in Aerospace Performance Factor calculation for years 2008 up to 2015.

Investment into safety is often seen as cost with little benefit; an obligation to meet standards rather than effort to truly improve on safety. Aviation industry of today already achieved excellent safety record and so it is hard to justify such investment in apparently resilient system. This study works with the assumption that safety and overall efficiency of operations are dependent. It analyzes data from safety occurrences in the aviation industry and provides mapping to relevant costs, both considering the remedy and possible prevention. It further provides base methodology for evaluation of current safety investments in the industry. In conclusion, the significant difference between costs related to remedy and prevention is used to justify trial of new technologies and measures to further improve on safety.

In recent years, the development of air traffic management safety is focused on utilization of safety key performance indicators. The goal of this article is to propose better method for safety indicators system evaluation than Aerospace Performance Factor method used by European Organization for the Safety of Air Navigation now. In the newly designed method, we use analytical hierarchy process to divide system to clusters and elements of clusters and quantitative pairwise comparison of criteria to evaluate indicators. This comparison gives responders new possibilities to accurate evaluation against the pairwise comparison method used now. The new method gives us accurate indicators weighting and more precise results of system’s safety performance. Than it is better to decide how to invest effort and resources.

Reaction time monitoring is currently routine in medicine and psychological practice. Monitoring of human reflexes concerning rapidly changing external visual stimuli in means of transport is one of the basic research activities in transportation sciences. These activities allow transfer of knowledge and innovations into practice. Human factors, especially in the aviation, can lead to significant fatalities. Selection of suitable candidates to perform such psychologically demanding occupation requires utilization of new testing tools and procedures. The basic idea to develop a device to measure reaction time was to offer suitable tool to physicians and research workers to explore human sensomotorics. The paper describes development of a new device to measure reaction time.

This paper focuses on the distinction between safety, quality and reliability in the context of operations and production management. Integrated management systems are readily available but the drivers for their implementation are often market or profit based whilst the actual contribution of proper management with regard to each of the areas is frequently matter of confusion, especially with regard to safety. In the first part, theoretical background with the highlights of distinctions and overlapping areas between safety, quality and reliability are identified and analyzed. Subsequently, a case study from the domain of transportation demonstrates application issues as well as opportunities to benefit from synergy effects. Conclusions provide a rationale for correct distinction between respective management processes and the long-term advantage of their effective integration.

The paper focuses on the issues concerning enhancement of the safety data management through understanding of the internal data structure and system behaviour. To build a strong system foundation based on safety knowledge, and to find a system on how to gather such knowledge are the key issues in modern safety engineering. Systematic data collection is not a new concept, however, the focus was always on quantity, while data quality was often misunderstood or hard to understand and be dealt with. A research topic was therefore focused on quality and content of the available data, covering the state of the incoming data, their wider classification, analytics and utilization through instruments creating safety intelligence. Having a large amount of data, means having an ability for potential system behavioural pattern identification. This is however strongly influenced by data structure and applied analytical methods. Identifying behavioural pattern in other words means articulating a certain signal generated through system, carrying information regarding system state, functioning and potential deviations. Due to a fact that such system manifests as a stochastic one, it is highly influenced by certain level of internal or external noise. The goal of the research is to examine system abilities for behavioural deviations detection and elimination of the negative, unnecessary and inadequate structures in data gathering process.

In practice, inexperienced pilots tend to excessively manipulate the aircraft control stick when attempting to direct an aircraft into a desired attitude. This causes piloting inaccuracies, which may lead to undesired flight situations. The objective of this paper was to identify the relationship between accuracy, or more precisely piloting error rate, and the physical activity of the pilot’s upper limb. Effort was also made to prove the fact that inaccurate upper limb input can be detected by means of values measured by an accelerometer. The evaluation was performed with 10 subjects during flight training with the main focus on evaluating the error rate during execution of climbing and descent 180° turn. The measurements were made on TRD40 flight simulator, evaluated by the proposed methodology of processing accelerometer data, and subsequently compared with real error rates calculated from flight data. The results confirmed a correlation between error rates inferred from flight data and error rates determined based on the accelerometer data. Because the research conducted in the domain is a pilot study, the results provide opportunities for discussion and possibilities of further research.

This paper deals with utilization of ontologies and conceptual structural models for improving safety data management in civil aviation maintenance, repair and overhaul organizations. It provides an overview of existing safety data management and identifies its shortcomings. Current approach to safety data management is based on global standards and regional regulations, which stem from long-term experience but recent development of advanced technologies and the demand for their versatile application creates new potential for further improvements of aviation safety. One of the technologies which have strong potential for application in aviation are ontologies and conceptual models. Ontologies deal with philosophy-motivated description of reality and conceptual models are ontology and object-oriented tools for building concrete description, the so-called conceptualization. Their value is recognized especially with regard to data management, such as data collection and processing. This is of extreme importance in modern knowledge management systems, such as safety management system, to optimize control mechanisms or to support research and development activities, which are highly sensitive to data quality, such as Safety-II concept. This paper explores the capabilities of the models with regard to current state-of-the-art in aviation maintenance and identifies strong points for domain application. Subsequently, framework for the technology deployment to the industry is outlined. Due to the non-existence of safety management requirements for aviation maintenance organizations and with regard to the current development of aviation safety in other aviation organization types, there exists strong willingness for such framework application and, according to the analysis performed, it represents one of the desired solutions for aviation industry.

At present, several studies exist describing the relevance of human factor in air transport with main focus on pilots and flight safety. Within such studies, monitoring of physiological functions is used. There are lot of physiological parameters and methods of their assessment; however, they are mostly based on principles originating from clinical practice. Yet, sensitivity and specificity of these methods with regard to assessment of aviation professionals - pilots is unknown. Therefore, this paper is oriented towards description of the most common methods for physiological parameters assessment. The paper also describes evaluation methods, which are on experimental level in terms of physiological data evaluation, namely recurrent quantification analysis. Within the research carried out, sample group of pilots was subjected to measurement for evaluation of their psychophysiological condition and performance. Selected evaluation methods were applied on the collected data and importance of those parameters and methods, which provided best classification for level of psychophysiological stress, was evaluated by means of statistical analyses. The results indicate that the most important physiological parameter for psychophysiological condition assessment of pilots is heart electrical activity where the possibility to perform signal processing whilst preserving its importance is provided by linear methods in the time and frequency domain, or alternatively by non-linear methods utilizing recurrent quantification analysis.

European Coordination Centre for Accident and Incident Reporting Systems (EC- CAIRS) develops an information system for reporting aviation occurrences on the European scale. The system makes use of various taxonomies, like the taxonomy of event types, or a taxonomy of descriptive factors. However, the ECCAIRS data model and associated taxonomies are complex and difficult to understand, which reduces interpretability of the records. In this paper, we discuss problems ECCAIRS users face during occurrence reporting as well as subsequent search in reported occurrences. Next, we show how proper conceptual modeling with ontological foundations could leverage quality of occurrence categorization and thus better exploitability of the EC- CAIRS system. We demonstrate our ontological model on the Aviation Vocabulary Explorer, our new prototypical tool for exploring ECCAIRS.

This paper deals with research of safety performance predictions to allow improved risk control in military. Safety performance is identified as appropriate tool to establish system-wide information on safety which can serve the decision making process on how to manage safety. The information contributes to better understanding of behavioural patterns in the controlled system and the ability to foresee short-term future can provide key elements for justification of remedial measures. Aviation safety data served the research due to confidentiality restrictions in military. Data deficiencies were addressed by the means of developed simulator. Suitable mathematical models were identified and autoregressive model was selected and applied to predict computed safety performance. At the end, it was possible to validate the model. Remarks on its potential application into real military environment conclude this work.

The Laboratory of Aviation Safety and Security at CTU in Prague has recently started a project aimed at runway protection zones. The probability of exceeding by a certain distance from the runway in common incident/accident scenarios (take-off/landing overrun/veer-off, landing undershoot) is being identified relative to the runway for any airport. As a result, the size and position of safety areas around runways are defined for the chosen probability. The basis for probability calculation is a probabilistic model using statistics from more than 1400 real-world cases where jet airplanes have been involved over the last few decades. Other scientific studies have contributed to understanding the issue and supported the model’s application to different conditions.

The idea of integrated aviation industry-wide safety (risk) management system and control mechanism require a common development level of the relevant sectors of included stakeholders. To construct such a system the three structural layers must be well defined, understood and functional. These are intra organizational, inter organizational and industry layer. As the name suggests, intra organizational layer include individual aviation organizations, subjects, their structure and systems. Inter organizational layer focuses on mutual relations between individual organizations or subjects, while industry layer includes a high-level mechanism controlling current state of safety and leading a strategic development. This paper focuses on the intra and inter organizational level by bringing a closer look into individual organizations’ processes and mechanisms used as a tool for a creation of the path leading to integrated safety (risk) management system, described in more detail in previous articles. It introduces a new approach and systematic changes needed for gathering more valuable safety related data, required for proactive management of the internal processes. Airports and other systems closely connected to them are taken as a main subject for the analysis. The main goal is to provide an explanation on how such internal structure should be set in order to become an efficient element of the proposed system.

Safety performance index is a tool with potential to grasp intangible domain of aviation safety, based upon quantification of meaningful aviation safety system properties. The tool itself was developed in form of Aerospace Performance Factor and is already available for the aviation industry. However, the tool turned to be rather unsuccessful as its potential was not fully recognised by the industry. This paper introduces performed analysis on the potential and it outlines new features, utilizing time-series analysis, which can improve both the recognition of the index by the industry as well as the motivations to further research and develop methodologies to evaluate overall aviation safety performance using its quantified system properties. This paper discusses not only the features but also their embedding into the existing approach to the development of aviation safety, highlighting possible deficiencies to overcome and relating the scientific work already performed in the domain. Various types of appropriate time-series methodologies are addressed and key specifications of their use with respect to the discussed issue concerning safety performance index are stated.

Flight simulator utilization for basic types of pilot training is restricted by regulations. Flight simulators could contribute to improvements of training quality, especially for initial training to obtain pilot license and, last but not least, to increase flight safety. The goal of this study was to evaluate flight simulator usability for basic piloting technique training. For this purpose, piloting error rate for 35 subjects was evaluated. Within prescribed, continuous flight simulator training consisting of 11 flight hours, progress in piloting precision was monitored during four different manoeuvers. The paper further evaluates influence of the transition between simulated and real flights with regard to progress or regress of executed manoeuvers precision. The results indicate, that during basic pilot techniques training on flight simulator, continuous and statistically significant decrease of error rate during standard manoeuvers execution is achieved. For acquisition of the habits related to mastering basic piloting techniques, the current possibility to use 5 training hours on flight simulator is insufficient. Habits acquisition is noticeable first during 11th flight simulator hour. The study also indicates that the acquired flight simulator habits related to piloting precision applying basic piloting techniques are not observable during the transition to real flights.

Psychological discomfort or increased stress can negatively influence performing specific activities mainly concerning professions which are responsible for human lives. Such group of professionals includes aviation specialists, especially pilots. Psychophysiological state is indicated by certain physiological parameters by means of which it is possible to describe it. There is a wide range of methods for signal processing of measured physiological parameters which are, however, based on linear methods. This paper deals with application of non-linear method, the so-called recurrence quantification analysis for evaluation of psychophysiological state of pilots. For this purpose, R-R interval recording of pilots in training was conducted by the means of wearable telemetric system. Research sample consisted of 35 beginner pilots and measurements were performed during both simulated and real flights. Measured signal processing was done using standard time-series analysis (Mean R-R and SDNN) and also using recurrence quantification analysis. The results indicate that both standard and recurrence quantification analysis parameters were able to distinguish between two groups of measurements (simulated vs. real flights) at the significance level of p<0.05. Apart from that, the results indicate considerable increase of heart rate frequency and decrease in its variability during real flights.

This paper introduces practical issues of implementing and deploying safety knowledge management software to aviation safety. Domain specific intangible nature of the issues concerned is described and all factors which prevent successful application of any knowledge management system are documented. Aviation organizations are struggling to find any effective solution which would on one hand allow timely tracking of the dynamic knowledge and on the other to not limit or bias reporters or investigators within the knowledge gathering process. The article deals mainly with practical issues concerning the deployment of reporting software, which constitutes the interface between humans and ontology model behind the software, capable to address trade-offs between various conflicting design criteria as well as many aviation organization types, as the aviation safety knowledge is to be gathered in cooperation with the industry.

The primer focus of the paper is to introduce a new concept of aviation industry approach to the risk management issues and following control activities. Due to its size, complexity and dynamic changes, which take place almost continuously, a platform was developed with one important goal, to help in creation of the industry-wide approach to the field of safety management. The approach is recognised as potentially beneficial for many entities involved. Such integration would enable a definition of the three aspects, which were introduced and further analysed - intra organizational, inter organizational and holistic aviation data approach. Each covers different layers or structure parts whose relations and definitions are both relevant and logical. All aspects represent different points of view, starting from the organisation level and leading to the field of the mutual activities involving various industry stakeholders and relevant authorities. Expected solution should ensure standardised approach to the reporting and following investigation. Ontological modelling would support an integration and development of the mutual risk assessment and control mechanisms. Building standardised aviation ontology, developed through one mutual system emerges as potentially powerful for application of various analytics instruments, e.g. business intelligence.

This paper introduces process modelling with regard to its potential to establish semi-automation of decision-making within safety management. High-risk industries are facing intangible nature of their safety-related issues, commonly involving human and system component interactions. To date, they typically utilize mental models to understand the processes, which they aim to control. This paper deals with the transition from mental models to the hybrid form of mixed mental and automated parts where the latter stem from partial formalisation of the existing process models. Issues with variables and their quantification are described and addressed accordingly within proposed solutions. These solutions are capable of formalising mental models and providing basis for automated elements that can reduce the burden of human controller. Interpretation and aggregation issues are outlined and links to both the control algorithms and sensors used by safety management are introduced. Aviation industry application is used to demonstrate the solutions.

According to the relevant sources, aviation industry as a whole is detecting a long-lasting safety improvement trend. This is true for all industry stakeholders such as airports, air carriers, handling agents, air traffic service providers and maintenance organizations. Extensive legislation and internal operational rules supported the establishment of the high standard system as well as efficient oversight for civil aviation authorities. Actual level of safety is often expressed as a ratio of the total number of accidents to the number of realized operational cycles. However, in today’s world, accidents are generally rare, hence authors integrate innovative approach to safety which enables safety performance evaluation. The approach utilizes safety performance indicators as fundamental tool in the process of evaluation. Nevertheless, the process is quite challenging due to the aviation complexity. This paper focuses on Runway Incursion, one of the major phenomenon in aviation safety. It has great potential to seriously affect safety during the most critical phases of flight – during takeoff and landing. Additionally, this paper presents results of descriptive and explanatory factors analysis. It outlines their implementation into the model, which will enable future safety performance quantification of the corrective measurements preventing Runway Incursion.

Air transport development brings an increased focus on the safety of piloting. The safety conditions can be assessed by mental workload. Psychic discomfort or excessive stress on pilots can negatively influence the course of flights. Therefore it appears convenient to monitor such parameters, which represent the mental wellbeing, or discomfort of a pilot. Since physiological measurements can provide a good information about mental workload or stress, this work primarily focuses on the observation of the change in heart rate, as it is an indicator of stress during the training of pilots, using the designed modular telemetry system. Another aim of this study is to evaluate the influence of a change in the avionic data visualization. This can have an unfavorable effect on the piloting of an airplane. This work, based on the evaluation of heart rate shows, that the switch from analog visualization to glass cockpit creates increased levels of stress in pilots, which was proved for all examined subjects except one. Significant level of correlation in the heart beat rate change in subjects in the course of training was also discovered.

Safety is one of the utmost importance in aviation, often globally and regionally emphasized. However, as the market became very competitive over the past years, safety is struggling to retain its ultimate importance from the perspective of aviation corporations and organizations. These are frequently under significant economic pressures and on safety being rather compliant with regulation than proactively concerned with it. This paper describes financial aspects and motivation issues of aviation organizations to allocate resources to safety management. Return on Investment and Bayesian Networks serve as the basic tools for assessing investments. Particular case study for missed approach scenario and simplified deliberation of costs typically involved in aviation safety-related occurrences are included. Results of the analysis are to motivate the corporations to take into consideration that thoroughly-targeted safety investments are not just expenses. Such investments do generate revenue, which may not be visible at a glance. The way how to calculate the estimated revenue of these investments is demonstrated as well.

Data quality is one of the modern issues in civil aviation safety. Today‘s accidents complexity requires painstaking analysis and in order to prevent the accidents it is necessary to collect and process operational data of adequate quality. That equals storing data in a form which allows their effective filtration and traceability for the need of their further processing and evaluation in time. This paper describes data quality improvement possibilities taking into account global aviation trends and also the needs and possibilities of civil aviation authorities, corporations and organizations. To this end, it utilizes several unified taxonomies, e.g. ICAO ADREP taxonomy and its European subset in preparation – RIT taxonomy, and HEIDI taxonomy by EUROCONTROL. Taxonomies are merged into a data collection and processing model which owing to the classification allows higher quality data storing. At thesame time, this article demonstrates how it is possible to set safety performance indicators utilizing stored high quality data within the organizations’ safety management system or state’s safety plan for the civil aviation safety oversight.

According to the relevant sources, aviation industry as a whole is detecting a long-lasting safety improvement trend. This is true for all industry stakeholders such as airports, air carriers, handling agents, air traffic service providers and maintenance organizations. Extensive legislation and internal operational rules supported the establishment of the high standard system as well as efficient oversight for civil aviation authorities. Actual level of safety is often expressed as a ratio of the total number of accidents to the number of realized operational cycles. However, in today’s world, accidents are generally rare, hence authors integrate innovative approach to safety which enables safety performance evaluation. The approach utilizes safety performance indicators as fundamental tool in the process of evaluation. Nevertheless, the process is quite challenging due to the aviation complexity. This paper focuses on Runway Incursion, one of the major phenomenon in aviation safety. It has great potential to seriously affect safety during the most critical phases of flight – during takeoff and landing. Additionally, this paper presents results of descriptive and explanatory factors analysis. It outlines their implementation into the model, which will enable future safety performance quantification of the corrective measurements preventing Runway Incursion.

The paper focuses on the taxonomies widely applied in the aviation industry. Beside the general view on the subject, article brings a description and mutual aspects identification of the presented taxonomies. Purpose, adequate comprehension and taxonomy application, together with the identification of the subjects to whom the taxonomy are dedicated were considered as the essential facts in taxonomy description. The human factor was recognised as a critical element in aviation and in that matter, several taxonomies specialised exclusively on that issue were mentioned. The new trends in the taxonomy development, their implementation in the particular systems together with benefits they could bring to the particular processes represent the important aspects of modern approach to the issue. The paper places emphasis on the common taxonomy, development supported by ICAO, and other hazard taxonomies.

All ICAO member States are currently implementing safety indicators in aviation. Requirements for their operation are contained in many legal documents, standards, and regulations, such as Annex 19 to the Chicago Convention, ICAO Doc. 9859, and regualtion (EC) 376/2014. Safety indicators for EU conditions are based on events data stored in the ECCAIRS database. High-level Safety Objectives that reflect a current need for improvement of the safety of the individual characteristics of the operation of the country can be also considered subject of safety indicators. For the operations with the indicators, the systems such as SDCPS (safety Data Collection and processing System) and SDTOS (safety Oversight Data Targeting System) need further development. The Basic principles for determining state-level safety indicators and operating principles of SDCPS and SDTOS are the content of this article.

This paper is focused on safety management and evaluation of its performance in organizations throughout utilization of key performance indicators regarding their operational efficiency. The efficiency is evaluated based on accepted safety measures and their application. The evaluation is ultimately possible due to improved occurrence reporting established via improved perception of safety by operation personnel; i.e. better perception of Safety culture. This paper describes safety management system principles applied within aviation organizations, moreover being required by European legislation. Key elements of safety management systems will be described and subsequently used for possible key performance indicators application for evaluation of their operational efficiency measurement. Even though this paper is based on application in aviation, it is not limited to it.

Řízení jakékoliv charakteristiky systému vyžaduje možnost provedení měření jeho kvantitativních i kvalitativních veličin. Analogicky vyplývá, že pro případ řízení letecké bezpečnosti musíme stanovit takové veličiny, abychom je byly schopni měřit a pomocí nich i řídit bezpečnost. Veličinami pro měření a řízení bezpečnosti jsou bezpečnostní indikátory, které mají v anglické literatuře zkratku SPIs (Safety Performance Indicators). V oblasti průmyslu existuje mnoho společností, které vykazují vyšší míru rizikovosti provozních procesů. Mezi takovéto společnosti patří například chemické továrny a jaderné elektrárny. V odborné literatuře se pro jejich pojmenování ustálil výraz „High-risk Industry“. Mezi takovéto společnosti ze své povahy patří i všechny organizace provozující leteckou dopravu. Pro dosažení akceptovatelné úrovně bezpečnosti zmiňovaných odvětví byly vyvinuty speciální systémy hodnocení založeny na indikátorech bezpečnosti zaměřených na problémové oblasti. Stejný trend v současnosti zaznamenáváme v oblasti letectví. Jelikož je bezpečnost podle nových metod možné řídit (zvyšovat) v reálném čase, upouští se od reaktivního sledování statistik nehodovosti. Bezpečnost je zvyšována preventivně a proaktivně – pomocí vyhodnocování indikátorů bezpečnosti, které umožňují bezpečnost měřit, její trendy porovnávat a na vhodné místo adresně směřovat nápravná opatření. Indikátor bezpečnosti je tedy pro organizace užitečným nástrojem, který stanovuje, zda jsou provozní procesy společnosti uvnitř tzv. bezpečnostního prostoru. Pro národního regulátora můžeme vytvořit také systém indikátorů. Takovýto systém musí poskytovat reálný pohled na současnou situaci. Z pohledu regulátora je patrně dobré vědět, které typy leteckých činností vykazují nejvyšší rizikovost, které typy provozních činností a událostí vykazují vzestupní trendy s nastupující letní sezonou.

Tento článok popisuje súčasný prístup k bezpečnosti leteckej dopravy na úrovni štátov. O zjednotenie tohto prístupu sa snaží ako medzinárodná organizácia pre civilné letectvo (ICAO) tak Európska únia. Štátna úroveň tomuto podlieha, ale vďaka ešte stále pomerne nerozvinutému prístupu na globálnej úrovni, táto umožňuje jednotlivým štátom problematiku rozvíjať individuálne na miestnej úrovni. Článok popisuje všeobecne platné požiadavky na uchopenie bezpečnosti leteckej dopravy prostredníctvom tvorby štátnych programov bezpečnosti (SSP) a ich kľúčových elementov daných od ICAO. Popisuje jednotlivé trendy riadenia bezpečnosti na úrovni štátu ako aj ďalší predpokladaný vývoj problematiky.

This paper aims to provide brief overview of aviation safety development focusing on modern trends represented by implementation of Safety Key Performance Indicators. Even though aviation is perceived as safe means of transport, it is still struggling with its complexity given by long-term growth and robustness which it has reached today. Thus nowadays safety issues are much more complex and harder to handle than ever before. We are more and more concerned about organizational factors and control mechanisms which have potential to further increase level of aviation safety. Within this paper we will not only introduce the concept of Key Performance Indicators in area of aviation safety as an efficient control mechanism, but also analyse available legislation and documentation. Finally we will propose complex set of indicators which could be applied to Czech Air Navigation Service Provider.
