Full textAbstract:
Purpose Most military aviation organisations today have not evolved their safety management approach towards harmonising with civil aviation. Safety culture is the base for any civil aviation organisation, enabling employees to communicate effectively and be fully aware and extrovert on safety. Just culture and reporting culture both are related to safety culture. Both are parts of the awareness process, enhancing safety promotion. These distinct elements and the safety management systems (SMS) can serve well the military aviation. This paper aims to present and discuss the SMS philosophy, structure and elements as a solution for military aviation organisations. Design/methodology/approach The feature of civil aviation SMSs are presented and discussed, with reference to the applicable frameworks and regulations governing the SMS operation. A discussion on the challenges faced within the military aviation organisations, with a brief examination of a European Union military aviation organisation, is presented. Findings The European Military Airworthiness Requirements, which are based on the European Aviation Safety Agency set of rules, can act the basis for establishing military aviation SMSs. A civil-based approach, blended, as necessary, with military culture is workable, as this is the case for many defence forces that have adopted such aviation safety systems. Originality/value This viewpoint paper discusses the opportunities and challenges associated with the adoption of SMS by military aviation organisations. This is the first time that this issue is openly discussed and presented to the wider aviation community, outside military aviation.

Full textAbstract:
The aviation safety community has traditionally measured safety performance through the lens of undesirable events – the historic recording, investigating and trending of the failures in the system. While this approach gives great insight into what has happened and why, it is of questionable value in determining what, where and when the next incident will occur. With the advent of the Aerospace Performance Factor or APF, aviation is taking a giant step toward a decision management solution that answers these questions and paves the way toward a revolution in safety performance measurement. The APF methodology is designed to expand the view of what information contributes to the aviation safety picture. The APF paints a broad landscape of organizational effectiveness by fusing weighted data from sources not traditionally included in the safety discussion, and then presenting the information in a way that assists aviation leaders in making better risked‐based decisions. This paper will discuss the APF from its to the progress of the initial and ongoing APF operational implementation, to its potential as a risk‐forecasting tool for the aviation industry.

Purpose Training management has critical in developing of civil aviation sector in Turkey. It requires using serious corporate sources for this reason is directly topic of aviation management and strategy.it is also about process management. According to this view, this paper aims to become a guidance to management training for maintenance or training organisations in the aviation sector wishing to obtain the authorisation, given national civil aviation authority (Directorate General of Civil Aviation), of providing type rating trainings that cover the types of aeroplanes including Beech 90 Series, Socata TB Series and Cessna/Reims-Cessna 172/F172 Series. Design/methodology/approach Aviation training organisations must be managed according to aviation law and regulations. It includes several approval processes about training content. Managers must be organising their resources, and they should get well timely decision made in optimum time. In this study, a flowchart, that is the procedure to follow in accordance with the related aviation regulations, has been developed while taking the opinion of experts and using experience gained from the approval process for the type trainings. This flowchart may gain time to managers in their approval process. It may use as guidance to create optimum flow in their process management. Findings The purpose of flowchart developed is to shorten the authorisation processes of the relative institutions by eliminating the challenges caused by the excess and complexity of national or international regulations related to the of authorisation of aircraft type rating training. Originality/value It is important to gain authority. But more important is to manage the authority as sustainable way in aviation training. Loosing authority in specific field may effect on both corporate reputation and doing aviation business. Anadolu University manages related risk via scientific project during using their authorisation. The results developed as a result of the expert opinions and the experience gained during the aircraft type training authorisation process will contribute to the literature. When considered from this point of view, it is expected for this study to fill an important gap in the literature. It is highly important for the aviation sector in terms of evaluating and interpreting academically such a process for practice, and also raising awareness or providing awareness for similar practices. It may also useful for process management.

Full textAbstract:
Purpose Each decision-making involves risk; therefore, risk is a strategic element in management and organization. In terms of risk management, the transformation process in organizations should be aimed at optimizing and improving the most important performance criteria such as cost, quality, flexibility and speed, rather than just as required by legislation. Transformation process has sustainability risks for organizations. ATO transformation process should be well designed. Process also should include clear steps to implement them. Sound and well-designed process will be useful for organizational performance and quality management. The management of the risks of conversion processes is vital for the continuation of operations without interruption. In aviation universities’ approved training organizations (ATOs), each system must be handled and processed separately. Transformation plans should be prepared considering the risks of each system. The purpose of this study is to develop process flowcharts of all systems in sustainable ATO transformation process from risk management perspective. Design/methodology/approach Flowchart method is useful to identify process risks in organizational system transformation. Flowcharts simplify communication and provide effective analysis of the process. Flowchart enables designing plan which is suitable for aimed results. Flowcharts method provides efficient coding and system analysis and program development phase also serves as a guide while debugging errors. In this study, flowcharts including all stages have been developed for transition to an ATO authorization. With these flowcharts, all elements of the process and the risks, threats and opportunities that may be faced can be proactively identified together. Thus, improvements will be possible to achieve the corporate objectives of the transformation and reorganization process and increase the corporate performance with optimum resource usage. Findings Flowcharts may contribute to the reorganization and transformation of processes in all aviation academies. In this sense, it provides infrastructure for future studies. New studies can be carried out for the reorganization of all departments in aviation. It is believed that this research will contribute to the aviation management literature. Flowchart is also called as process flowchart or process flow diagram. Flowchart is effective methodology to manage transformation process risk. Owing to clarify each step in transformation process, risks may be managed with timely decision-making by managers. In this research, five fundamental flowcharts have been developed in ATO system. These include all processes in transformation as preparation of manuals, new authority application, competent authority inspections, corrective and preventive actions, revalidation and fees in transformation process and its parts. Presented flowcharts may be useful to identify and manage process risk in initial phase as consent with proactive management style. Research limitations/implications This research presents designed flowcharts for ATO transformation risk management process. This research may extend at other departments in aviation universities such as air traffic control, maintenance and management. Practical implications As a methodology, flowcharts can be considered as schematic algorithms. The flowchart is a detailed representation of the process to carry out a specific task. In this research, flowcharts have been developed for transformation process stages at ATO authorization. These flowcharts are useful for proactive identification of process elements and their risks – threats and opportunities. Thus, improvements will be possible to achieve the corporate objectives of the transformation and reorganization process and increase the corporate performance with optimum resource usage. Flowcharts may contribute to the reorganization and transformation of processes in all aviation academies. In this sense, it provides infrastructure for future studies. New studies can be carried out for the reorganization of all departments in aviation. It is believed that this research will contribute to the management and strategy literature with engineering. Originality/value ATO transformation process risk management has not been studied much in literature. The operational manuals of ATO's management and strategy planning prepare according to both legal regulations and handbooks of aviation authorities which obliged for ATO. It is anticipated that this original study may be useful for determining the risks of transformation processes of flight training departments of civil aviation universities and for good process design. Flowcharts may contribute to the reorganization and transformation of processes in all aviation academies. In this sense, this study provides infrastructure for future studies. New studies can be carried out for the reorganization of all departments in aviation. It is believed that this research will contribute to the aviation management literature. Flowchart is also called as process flowchart or process flow diagram. Flowchart is effective methodology to manage transformation process risk. Owing to clarify each step in transformation process, risks may be managed with timely decision-making by managers. The aviation universities operate with authorization. This research may contribute to their process management and strategy to complete their transformation and transition via risk management. Developed flowcharts present all necessary steps to become authorized as an ATO. This research may serve as a kind of framework guide for other aviation organizations to be used in their transformation/transition process.

Full textAbstract:
At the heart of airline flight safety management is a systematic approach to identifying hazards and controlling risk factors, which ICAO requires to collect, analyze all deviations in the activities of units, services and personnel airlines and use of its results to develop and implement management activities. That kind of the system enables the organization to predict and fix problems before they lead to an aviation accident. Thus, the organizational management structure should ensure high efficiency, reliability and completeness of the control over all components that ensure the process of the air transportation: the course of transportation, the clear operation of all units in the uninterrupted transport process and their correct matching. In modern conditions, this result is achieved based on a process approach, when the company’s activities are presented as a set of production processes (activities). For each of these areas, the airline has appropriate management systems that are developed, certified, implemented and operated in accordance with international standards. As a result of the interaction of these processes, the goals of the aviation enterprise, which determine its competitiveness, are achieved.

In Air Traffic Management (ATM), Safety Management Systems (SMS) provide the principal vehicle for implementing safety policies, practices and procedures in accordance with internationally agreed Standards. In a constantly changing operating environment, it is essential to maintain SMS effectiveness to maintain and enhance levels of ATM safety. Research at the University Politehnica of Bucharest (UPB) has analysed the major, fast-rising threats to ATM safety emerging in the field of unmanned aviation. After considering the operating environment in terms of control arrangements and unmanned vehicle types, the relationship between ATM and Unmanned Traffic Management (UTM) is examined. It is concluded that the SMS supporting ATM requires enhancement to address the risks arising from the emergence of unmanned aviation and relevant enhancement measures are therefore proposed. Further, research shows that detailed safety management arrangements to support UTM are not yet defined. Indicative SMS requirements for UTM are therefore derived and presented.

Full textAbstract:
In this study, three Line Operations Safety Audits (LOSAs) on an airline are carried out, their results are compared with each other, and a comparison is also made between domestic and international fleets. The LOSA is a proactive and predictive method in the Safety Management System that detects the strengths and weaknesses of airline performance under normal operations. Furthermore, it is a tool to improve the safety margin. The LOSA process is implemented on the basis of ten operating characteristics. Once the data for each LOSA was gathered and processed, the results for the three were compared. Surveys show that LOSAs provide a monitoring system for the Threat and Error Management of old generation aircraft. Domestic and international airline fleets confront different types of threats and errors in different flight phases. It is concluded that the syllabuses of training courses should be different for flight crew with respect to their fleet and the threat and error types. That are most common the obtained results can promote the importance of airlines’ Threat and Error Management based on their fleet type in the future.

In the late 1970s, there were several aviation accidents that would affect the future of air transportation (Pan Am / KLM's flight ended fatally near Tenerife with 583 casualties, as well as another one in Portland, Oregon, where United Airlines experienced the crash of his aircraft in which 173 passengers and crew members were killed). Overwhelmed by the burden of these events, the NTSB[1] was forced to investigate the causes of these severe aviation accidents, and stunning data were obtained which revealed that in most cases the errors were caused by ground or pilot personnel. Confirmation of these conclusions was provided by the research of NASA[2], which established that 70% of all aviation accidents are direct human error. All this influenced the development of crisis management in airlines, which will change their previous organization, also the management of all segments of flight of the aircraft. Although the experience in aviation crisis management is very significant, many companies still do not pay enough attention. Underdeveloped crisis management and non-compliance with security procedures in the Russian private company Spa Air in 1996 on the line Belgrade-Malta will lead to the loss of the aircraft and the death of the crew.

The case study is focused on the application of principal quality tools in a fourth generation jet fighter to evaluate a maintenance activity in an accident investigation process. The paper assesses aircraft engineers’ performance on checking aircraft tyre inflation pressure before the aircraft’s flight. Process evaluation is organized by the application of fundamental quality tools in order to provide vital information regarding the level of control. The methodology combines the benefits of statistical quality control, root cause determination, and preventive actions, to eliminate maintenance discrepancy in the future. The methodology revealed an approach to generate useful safety metrics from incident reporting data. Furthermore, this study pointed out the significance of participation at all technician levels for the successful implementation of Total Quality Management (TQM). Also, it discusses the value of TQM in aviation and suggests that continuous improvement is still needed. The paper is based on practical work being undertaken in a military squadron and, therefore, is demonstrated to be practical in an aviation environment. This study would encourage aviation personnel to rely on TQM methods for performing quality assessment monitoring and achieving continuous improvement.

Full textAbstract:
An issue of improving flight safety during landing with an inertial navigation system (INS) and a failed barometric altimeter is considered. In this paper, we propose a specific algorithm for in-flight calibration of the vertical channel of INS. Accordingly, the baro-inertial integration algorithm using a discrete five-state Kalman filter will be performed during a particular flight maneuver before landing. As a result, it is possible to estimate not only the bias of vertical accelerometer but also its scale factor, which is too small to be defined by a usual in-flight calibration algorithm. After applying the proposed algorithm, the flight management system can provide a safe landing with a standalone INS. The algorithm’s performance is assessed by simulating complete mathematical models of aircraft motion and control systems. The impact of calibrated bias and scale factor of vertical accelerometer on the altitude estimation error is provided through an analysis.

This paper proposes a new airport typology that might arise from the expansion of airports with dominant low cost carrier traffic. In the first part of the paper, the typologies and different airport categorizations are reviewed with examples of current taxonomies used by principal international organizations. However, none of the current airport taxonomies takes into account low cost (LCC) carriers and cannot be used to create an airport market strategy with LCC operation. The paper highlights the characteristic of LCC features, the differences between the LCC airlines, and the characteristics of secondary – low cost airports. Finally, the paper proposes a new taxonomy of airports with low cost operations based on the airport data analysis and expert panel elucidation. For identification of airports with a high share of low cost carriers, Eurocontrol 2013 data on airline types and movements were used. The novel classification of low cost airports enables management to design marketing strategies to respond to LCC dominance and its implications. The main contribution of this research is to provide a novel classification for low cost airports which is relatively new phenomenon comparing with the problems of full service carriers dominance at large airports.

Full textAbstract:
An effective risk assessment approach for assessing the risk level of aviation emergency rescue is essential to aviation emergency management. Therefore, this study is aimed at extending a novel integrated multiattribute group decision-making (MAGDM) approach to conduct risk assessment in aviation emergency rescue. First, a combined improved Swiss cheese model and fault tree analysis method are used to build the index system for risk assessment. Next, the weight vector for risk assessment is calculated using the consensus-based improved analytic hierarchy process (IAHP). Then, based on the traditional technique for order preference by similarity to the ideal solution (TOPSIS) method, we improve the definition express of ideal solution and the standardized formula of indexes, thereby providing a consensus-based improved TOPSIS method to compute the evaluation matrix for risk assessment. Finally, the weight vector and evaluation matrix are combined to estimate the risk level of aviation emergency rescue. As aviation emergency rescue in a sudden natural disaster an example, we illustrate the feasibility of the proposed method and demonstrate its effectiveness by comparative analysis with some similar approaches. The proposed approach can evaluate the safety status of aviation emergency rescue operations, which provides a starting point for the improvement of aviation emergency rescue.

This article deals with the review of the main parameters and assessment of a quality system. A quality assurance system and its management are of great importance to an aviation organization whether it is large or small. The final task of the quality system is to ensure the technical aircraft maintenance system at a high level of quality, to ensure airworthiness of the aircraft. In our days Total Quality Management (TQM), as a new philosophy, is gaining power in civil aviation. Seeking quality is vital for maintenance organization for such reasons as the survival of the organization and competitiveness in the market. TQM is directly connected with the ISO 9000:2000 series standard implementation and involves many other parameters such as the qualifications of personnel and training. As an instrument for control, an audit, done by themselves or by an outside company, is indicated.

Purpose The ability to learn from previous events in support of preventing future similar events is a valuable attribute of aviation safety systems. A primary constituent of this mechanism is the reporting of incidents and its importance in support of developing learning material. Many regulatory requirements clearly define a structure for the use of learning material through organisational and procedural continuation training programmes. This paper aims to review aviation regulation and practice, highlighting the importance of learning as a key tenet of safety performance. Design/methodology/approach Applicable International Civil Aviation Organisation requirements and the European Union (EU) regulation in aircraft maintenance and continuing airworthiness management have been critically reviewed through content analysis. Findings This review has identified gaps in the European implementing rules that could be addressed in the future to support a more effective approach to the delivery of lessons in the aircraft maintenance and continuing airworthiness management sector. These include light-touch of learning and guidance requirements, lack of methodologies for the augmentation of safety culture assessment, absence of competence requirements for human factors trainers and lack of guidance on standardised root-cause analyses. Practical implications This paper offers aviation safety practitioners working within the European Aviation Safety Agency regulatory regime an insight into important matters affecting the ability to learn from incidents. Originality/value This paper evaluates critically and independently the regulation and practice that can affect the ability of EU regulated aircraft maintenance and continuing airworthiness management organisations to learn from incidents. The outputs from this research present a fresh and independent view of organisational practices that, if left unchecked, are capable of impeding the incident learning process.

Full textAbstract:
Many attempts have been made to reduce aviation’s environmental impact, as aviation traffic has grown exponentially in recent decades. While some approaches focus on technology and fuel alternatives, others strive to develop improved operational measures within air traffic management as a short-term action to mitigate aviation-induced climate change, as well as air pollution. In this work, different flight procedures are analyzed in terms of emissions and noise impact to define optimal trade-offs. The investigation is based on flight data recorders, emissions, and noise prediction models. An aircraft trajectory simulation code with flight procedure optimization is also implemented to define an environmentally optimal trajectory. The results show that while noise and the emissions proportional to the burned fuel may be reduced for some trajectories, other non-CO2 emissions could drastically increase if too low idle-thrust levels are reached. Therefore, a minimum threshold for idle thrust is suggested as a key factor to define a truly optimal trajectory in terms of CO2 emissions, non-CO2 emissions, and noise.

Purpose Aviation has multi-cultural business environment in all aspects as operational and management. Managing aviation requires high awareness on human factor risk which includes organizational behavior-related topics. The greatest risk to an enterprise’s ability to achieve its strategic goals and objectives is the human factor. Both organizational behavior and corporate culture behavior with social psychology are the most vital aspects of management and strategy in terms of human resources. Related risks, including organizational behavior and culture, have the potential to directly impact on both business performance and corporate sustainability. Therefore, in this paper, the most prominent risks were determined in accordance with social psychology, and after identification of human factor-based risks, these have prioritized and prepared risk mapping with fresh approach. For this reason, this study aims to develop risk mapping model for human factors that takes into account interrelations among risk factors three dimensional based new approach. This approach includes both identification of human factor based risks, prioritization them and setting risk mapping according to corporate based qualifications via tailoring risk list. Developed risk map in this paper will help to manage corporate risks to achieve improved performance and sustainability. Design/methodology/approach This new organizational behavior- and culture-focused risk mapping model developed in this study has the potential to make significant contribution to the management of the human factor for modern management and strategy. In enterprise risk management system, risk mapping is both strong and effective strategic methodology to manage ergonomics issue with strategic approach. Human factor is both determinative and also strategic element to both continuity and performance of business operations with safely and sound. In view of management and strategy, vitally, the human factor determines the outcome in both every business and every decision-making. Findings It is assumed that, if managers manage human risk you may get advantages to achieving corporate strategies in timely manner. Aviation is sensitive sector for its ingredients: airports, airlines, air traffic management, aircraft maintenance, pilotage and ground handling. Aim of this paper is to present risk management approach to optimize human performance while minimizing both failures and errors by aircraft maintenance technician (AMT). This model may apply all human factors in other departments of aviation such as pilots and traffic controllers. AMT is key component of aircraft maintenance. Thus, errors made by AMTs will cause aircraft accidents or incidents or near miss incidents. In this study, new taxonomy model for human risk factors in aircraft maintenance organizations has been designed, and also new qualitative risk assessment as three dimensions is carried out by considering the factors affecting the AMT’s error obtained from extensive literature review and expert opinions in the field of aviation. Human error risks are first categorized into two main groups and sub three groups and then prioritized using the risk matrix via triple dimension as probability, severity and interrelations ratio between risks. Practical implications Risk mapping is established to decide which risk management option they will apply for managers when they will look at this map. Managers may use risk map to both identify their managerial priorities and share sources to managing risks, and make decisions on risk handling options. This new model may be a useful new tool to manage ergonomic human factor-based risks in developing strategy in aviation business management. In addition, this paper will contribute to department of management and strategy and related literature. Originality/value This study has originality via new modeling of risk matrix. In this study, dimension of risk analysis has been improved as three dimensions. This study has new approach and new assessment of risk with likelihood (probability), impact (severity) and interrelations ratio. This new model may be a useful new tool to both assess and prioritize mapping of ergonomic-based risks in business management. In addition, this research will contribute to aviation management and strategy literature and also enterprise risk management literature.

Abstract Commercially-driven air traffic management (ATM) innovations typically aim to increase air space capacity and/or reduce delays. Here, their potential application for environmental mitigation is discussed. Both carbon dioxide (CO2) and non-CO2 climate impacts are considered, as are noise and air quality issues. We outline the technological, scientific and political barriers to an integrated approach to applying ATM technologies to environmental mitigation. These issues highlight the need to improve comparison and prioritisation of the emissions and effects of aviation.

With civil aviation growing at around 4.7% per annum, the environmental footprint of aviation is increasing. Moreover, the use of kerosene as a fuel accelerates the depletion of non-renewable fossil fuels and increases global warming. Hence, the aviation industry has to come up with new technologies to reduce its environmental impact and make aviation more sustainable. An electrically assisted propulsion system can combine the benefits of an electrical power source with a conventional turbofan engine. However, the additional electrical system increases the weight of the aircraft and complexity of the power management system. The objective of this research is to analyze the effect of an assistive electrical system on the performance of a turbofan engine for an A320 class aircraft on a short-range mission. The developed simulation model consists of an aircraft performance model combined with a propulsion model. The power management strategy is integrated within the simulation model. With the proposed propulsion system and power management strategy, the electrically assisted propulsion system would be able to reduce fuel burn, total energy consumption, and emissions for short-range missions of around 1000 km.

Purpose In this study, a multi-criteria decision-making (MCDM) approach for evaluating airworthiness factors were presented. The purpose of this study is to develop an acceptable rationale for operational activities in civil and military aviation and for design, production and maintenance activities in the aviation industry that can be used in-flight safety programs and evaluations. Design/methodology/approach In aviation, while the initial and continuing airworthiness of aircraft is related to technical airworthiness, identifying and minimizing risks for avoiding losses and damages are related to operational airworthiness. Thus, the airworthiness factors in civil and military aviation were evaluated under these two categories as the technical and operational airworthiness factors by the analytic hierarchy process and analytic network process. Three technical and five operational airworthiness criteria for civil aviation, three technical and nine operational airworthiness criteria for military aviation were defined, evaluated, prioritized and compared in terms of flight safety. Findings The most important technical factor is the “airworthiness status of the aircraft” both in civil (81.9%) and military (77.6%) aviation, which means that aircraft should initially be designed for safety. The most significant operational factors are the “air traffic control system” in civil (30.9%) and “threat” in the military (26.6%) aviation. The differences within factor weights may stem from the design requirements and acceptable safety levels (frequency of occurrences 1 in 107 in military and 1 in 109 in civil aircraft design) of civil and military aircraft with the mission achievement requirements in civil and military aviation operations. The damage acceptance criteria for civil and military aircraft are different. The operation risks are accepted in the military and acceptance of specific tasks and the risk levels can vary with aircraft purpose and type. Practical implications This study provides an acceptable rationale for safety programs and evaluations in aviation activities. The results of this study can be used in real-world airworthiness applications and safety management by the aviation industry and furthermore, critical factor weights should be considered both in civil and military aviation operations and flights. The safety levels of airlines with respect to our airworthiness factor weights or the safety level of military operations can be computed. Originality/value This is the first study considering technical and operational airworthiness factors as an MCDM problem. Originality and value of this paper are defining critical airworthiness factors for civil and military aviation, ranking these factors, revealing the most important ones and using MCDM methods for the evaluations of airworthiness factors for the first time. In civil aviation flight safety is the basic tenet of airworthiness activities in risk analysis, on the other hand in military aviation high levels of risks are to be avoided in peace training or operational tasks. However, even high risks have to be accepted during the war, if the operational requirements impose, as mission achievement is vital. The paper is one of a kind on airworthiness evaluations for flight safety.

Safety is generally characterised as the state of being “safe”, the condition of being protected from harm or other non-desirable consequences. One effective way of achieving it is to implement a safety management system (SMS). SMS should be seen as an aggregate strategic aspect of standard business management, understanding its high priority to safety. This article describes and illustrates SMS in aviation, focusing on the similarities and differences in the system approaches adopted by selected Civil Aviation Authorities (CAAs) with the primary focus on the safety level. The main goal is to provide a structural comparison of the system framework within individual CAAs and its explanation in safety-related documents. This article also dealt with the chosen safety approach (reactive, proactive and predictive) and safety performance indicators (SPIs), forming a quality and effective safety system that maintains an acceptable safety level. Finally, this article is mainly based on datasets publicly available through the International Civil Aviation Organisation, Transport Canada, Civil Aviation Safety Authority Australia, Federal Aviation Administration, UK Civil Aviation Authority, Civil Aviation Administration of China and Civil Aviation Authority of New Zealand websites and documentation related to safety.

AbstractFatigue management in military aviation remains problematic and can be easily neglected by planners and aircrew in a busy operational environment. The basic assessment tool (BAT) is an objective and educational computer tool for evaluating and combining various fatigue factors. It provides an impartial performance comparison while at the same time educating and reminding its users of the importance of fatigue management. Individual factors of the BAT were chosen because they affect fatigue, sleepiness, alertness and performance. A short explanation of components not chosen is also included. An example of how the BAT can be used is described and figures of the resulting outputs (screenshots) are included. Most commercial fatigue estimation products are subjective and do not consider specific issues associated with tactical operations in a field environment. This novel approach can be used to help plan missions by minimizing the BAT score while still maximising the tactical advantage and keeping fatigue management fresh in the minds of military rotary wing pilots while in training and on operations. Although the BAT is military aviation focused and objective, it can be easily modified to suit particular fatigue concerns.

This article is devoted to issues of network interaction in the aviation industry in Russia, taking into account the trends and conditions of digitization. Networking is essentially the best way to integrate business, scientific and educational organizations and authorities. Digitization allows management decisions to be made faster and more efficiently, especially with the help of IT, to accelerate the creation and commercialization of innovations, and to engage new stakeholders in networking. Each interaction participant benefits from digital networking. In turn, the aviation industry is a priority for Russia and for other leading countries of the world. The article considers the possibility of developing network interaction in the aviation industry of Russia in the direction of creating an aerospace composite cluster in the context of digitalization. The experience of other Russian regions in which aviation clusters have already been formed has been analyzed. An analysis of the dynamics of industrial production capacities showed that the regions in which aviation clusters began to function show a significant positive dynamics in the volumes of shipped products. The development of network interaction in the aviation industry will increase the innovative component in the industry, strengthen the competitiveness and stability of the aviation industry in the context of digitization. One of the most significant processes in the framework of network interaction is the transfer of knowledge and technology especially with helping of IT.

Abstract Recently, the European Aviation Safety Agency and other civil aviation authorities introduced a regulatory framework for low- and medium-risk operations of unmanned aerial systems (UAS) where medium-risk operations fall into the ‘specific’ category. Other introduced categories are the ‘open’ category for very-low-risk operations and the ‘certified’ category for high-risk operations that are comparable to manned aviation. This framework has the potential to reduce the certification costs compared to manned civil aviation. This paper discusses the challenges for operators of high-altitude platforms who aim for medium-risk UAS operations in the ‘specific’ category. It also shows ways to obtain an operation approval in the ‘specific’ category and how to deal with the associated operational requirements to perform such long-endurance UAS missions. Moreover, problems the high-altitude platform operator has to face when applying SORA are discussed. The paper closes with a promising approach to further enable high-altitude operations and to face some of the problems that occurred in the applicability of SORA to high-altitude platform operations by the use of 4D-operational volumes and unmanned traffic management (UTM) services.

Every day over 102.000 commercial passenger flights take place on a global scale above our heads. Because of that many questions arise in the areas of safety and security in massive air traffic. If airlines use crisis management, any activity concerning the preparation of the crew and the aircraft for a particular task - flight gets more significance and importance. During the flight, the pilot - the captain of the aircraft, is the key person of any company activity that includes transport of people and goods, and that is the reason why a pilot's psycho-physical abilities and flying performance must be constantly checked, evaluated and improved. In a plane crash near North Macedonia's capital city Skopje, the aviation investigators discovered the number of serious failures in pilot training that led to the fall of a private plane Cessna 340. The investigation revealed that although the pilot was certificated to fly in instrument meteorological conditions, his actions in the air indicate that he was not well trained. European and American aviation authorities have clear legal regulations regarding the training and certification for individual flight categories as well as a categorized simulation technique where pilots exercise before they get one of the flying categories. Flight simulators play an essential role in the training of the future pilots for both visual and instrumental flight conditions

PurposeContemporary management and strategy mean optimization of ingredient factors such as human factors, systems, operations and equipment. With system approach in management and strategy, human risk factor as input has considerable potential to change results as airworthiness in aviation management. The managers of aviation business also optimize their functions to act safe while making contribution to development in triple of sustainability as economic development and its sustainability; social development and its sustainability; and environmental development and its sustainability. Corporate sustainability can be accomplished via supporting workforce which is the human risk factor. To support (empowerment) workforce, researchers should identify human risk or error factors which are important to this research. The purpose of this study is to suggest holistic framework for working environment system of aircraft maintenance technicians (AMTs) within two respects such as human performance (ergonomics) and corporate performance (sustainability). The secondary purpose of this system is to develop human risk taxonomy by determining the factors affecting both human and work by taking ergonomic aspects in aviation.Design/methodology/approachIn this study, a taxonomy of human risk factors for AMTs is developed. These human factors divided into groups and subfactors are obtained from an extensive literature review and experts’ opinions in the field of human performance in aviation. Taxonomy developed will be useful to both sharing and using corporate sources in sustainable way.FindingsHuman risk factors can be considered or accepted as factors that cause human error. This may result in the optimum way to managing human risk factor via minimizing human-based error. Personality, hazardous attitudes, individual characteristics, physical/psychological condition of AMTs and corporate social responsibility factors are human-related risk variables in this study. The risks and error can be reduced by recognizing these factors and revealing their relation to ergonomic design.Originality/valueThe results of this study are intended to constitute a guide for managers to manage risk factors and to take corrective and preventive actions for their maintenance operations. It is believed that this study is highly important for the aviation sector in terms of raising awareness or providing awareness for similar practices. As taxonomy of the risk factors contributes to the managing human error, corrective actions related to these factors must be taken by managers.

In the last 40 years, the aeronautical industry has managed to move from a specialized sector to a worldwide leading industry. Companies, governments and associations all over the world acknowledge the importance of the aviation industry in supporting global development and the economy. However, aviation will be facing new challenges related to sustainability and performance in a technological environment in evolution. To succeed, the aeronautical industry must keep innovation as one of its main assets. It must master a wide range of technologies and then collaborate to integrate them into an aircraft design and development program. A collaborative approach to innovation is key to achieve these goals. The main purpose of this paper is to analyze the structure of technological innovation networks in the aviation industry and to characterize the map of the “Aviation Technology Space”. Two different approaches and methods are used. In one approach, we performed a bibliometric network analysis of aviation research scientific publications using a keyword co-occurrence analysis method to map the aerospace collaboration structures. Complementarily, we performed a patent analysis to evaluate the innovation capacity of the aviation industry in the cutting-edge technologies previously identified. From the results of this analysis, the paper provides recommendations for future innovation and research policies to allow the sector to fulfill the demanding goals by the year 2050.

A wide regulatory reform is taking place world-wide in the continuing airworthiness domain. The major influences for promoting changes in how continuing airworthiness is managed are civil and military aircraft accidents to which fatigue, corrosion, wear, deterioration in ageing aircraft and the need for regulatory harmonisation of the International Civil Aviation Organisation (ICAO) signatory states and the military were the contributing factors. Another emerging factor is the conversion of older passenger aircraft to freighters, which brings forth the concern that aircraft are being used in a capacity for which they were not designed. The challenges of the regulatory reform are acceptance, certification of maintenance organizations and personnel, education and training, as well as information sharing and administration. This paper presents both the drivers and challenges in these areas and proposes a related change management framework.

Full textAbstract:
The aviation industry has committed to decarbonize its CO2 emissions. However, there has been much less industry focus on its non-CO2 emissions, despite recent studies showing that these account for up to two-thirds of aviation’s climate impact. Parts of the industry have begun to explore the feasibility of potential non-CO2 mitigation options, building on the scientific research undertaken in recent years, by establishing demonstrations and operational trials to test parameters of interest. This paper sets out the design principles for a large trial in the North Atlantic. Considerations include the type of stakeholders, location, when to intervene, what flights to target, validation, and other challenges. Four options for safely facilitating a trial are outlined based on existing air-traffic-management processes, with three of these readily deployable. Several issues remain to be refined and resolved as part of any future trial, including those regarding meteorological and contrail forecasting, the decision-making process for stakeholders, and safely integrating these flights into conventional airspace. While this paper is not a formal concept of operations, it provides a stepping stone for policymakers, industry leaders, and other stakeholders with an interest in reducing aviation’s total climate impact, to understand how a large-scale warming-contrail-minimizing trial could work.

Such a body is subject to various tasks and limitations supporting the achievement of its targets, it is not a manufacturer or service supplier and it is not similar to other kind of governmental agencies. This paper should provide a model to develop guidance on QMS applied to the very specific case of a civil aviation safety investigation agency.

Civil aviation is one of biggest industrial contributors to CO2 emissions worldwide. One of the most urgent problems of this sector is providing new technologies to continue operating in a more sustainable environment through a transition to clean energy. The Earned Value Management (EVM) model, as a traditional project management tool, is continuously being revised with new releases and extensions (e.g., ESM, EDM, QEVM, E-EVM, and ZEVM), but to date none of them has applied an expert judgment criterion to be able to modify and anticipate the final result of the project. In such a way, this paper introduces a novel approach to the topic with the so-called Enhanced and Efficient Earned Value Management (denoted E2-EVM) model by including this new capability through the real options methodology, thus helping to support the sustainability of the aerospace sector. This research focuses on three main goals: the description of recent green initiatives in the aerospace sector by checking its contribution to reaching the well-known Sustainable Development Goals (SDGs), the development of a new version of the EVM model by applying the real options methodology, and, finally, the financial contribution to the aerospace industry by applying these initiatives and methodologies.

Full textAbstract:
In the aerospace manufacturing, lots of processes cannot be automated and are performed manually by skilled workers. Because there exist some human error mistakes in such manual working processes, root cause investigations of these mistakes are indispensable and measures are implemented in working processes for preventing repetition of the same mistakes. Although skilled workers have strong confidence that they can complete their work with no mistake, there exist some cases that they cannot recognize their mistakes in practice. In such cases, root cause investigations cannot be performed and no measure is implemented. Such situation may become a serious risk in aerospace manufacturing because a tiny mistake can cause the serious mission failure of aviation system. To reduce such situation, the ergonomic risk reduction method is proposed. Skilled workers try to avoid frustration in performing their tasks and make mistakes through careless behavior. The cause of the frustration is discovered by ergonomic risk reduction method. Work risks can be removed by the progress of the working environment. Such risk reduction method contributes manufacturing organization resiliency. In this paper, we propose an ergonomic human error risk reduction method for skilled workers in Japanese domestic liquid rocket engine manufacturing.

Understanding a definite geographic context is essential for effective air transport management. To date, the consequences of changing weather conditions and climate on the transportation sector in Ghana has been grievous to the economy of the country. Unfortunately, the impact of climate change on the aviation industry has received very little attention in Ghanaian literature. Meanwhile, it is widely known that transport systems on the whole perform poorly under adverse weather and climatic conditions. This paper seeks to reflect a growing orientation in research and philosophy in the field of air transport and severe weather and climatic constraints. Understanding under-lying principles of climatic conditions and weather is essential to air navigation in Ghana. Clear air turbulence, ceiling and visibility, thunderstorms, electrical phenomenon, climate-induced seasonal variations, and vegetation are some of the threats to air transport across Ghana's airspace. Information is derived from literature surveys, workplace counts, and an aviation researcher. Overall, large information technology investments, consolidation, and re-structuring are all major issues that must be addressed by stakeholders ambitious to stay afloat and competitive in Ghana's airspace.

INTRODUCTION:The neurological impact (or lack thereof) of certain medical histories and imaging findings is important to understand in the context of air and spaceflight. There are a number of neurological conditions that, if present in pilots and astronauts, carry variable (and sometimes adverse) functional implications for safety and overall mission success. In this systematic overview, the authors will refer to the relevant clinical and radiological features of brain tumors and vascular anomalies, cerebral edema and intracranial hypertension, concussion and the traumatic brain injury (TBI) spectrum, hematomas, cerebrospinal fluid circulation anomalies including hydrocephalus and sequestrations, spinal degenerative changes, and cerebral ischemia and demyelination. It is notable that these last two conditions have recently been reported to be a complication in some people with coronavirus disease 2019 (COVID-19). A paradigm for practical neurological workup of symptomatic pilots and astronauts will be discussed, as will the controversial notion of pre-emptive radiological screening (vs. not screening) in asymptomatic or clinically occult situations. The concepts of medical surveillance in the setting of known or diagnosed pathologies, and expert panel review and simulator and flight checks in complex neurological cases, are also elaborated on in this paper. We believe this overview will contribute toward the enhancement of a broad understanding of neurological conditions, their clinical workup, and their precautionary management in the setting of aviation and aerospace.Khurana VG, Jithoo R, Barnett M.Aerospace implications of key neurological conditions.

As the global search for new methods to combat global warming and climate change continues, renewable fuels and hydrogen have emerged as saviours for environmentally polluting industries such as aviation. Sustainable aviation is the goal of the aviation industry today. There is increasing interest in achieving carbon-neutral flight to combat global warming. Hydrogen has proven to be a suitable alternative fuel. It is abundant, clean, and produces no carbon emissions, but only water after use, which has the potential to cool the environment. This paper traces the historical growth and future of the aviation and aerospace industry. It examines how hydrogen can be used in the air and on the ground to lower the aviation industry’s impact on the environment. In addition, while aircraft are an essential part of the aviation industry, other support services add to the overall impact on the environment. Hydrogen can be used to fuel the energy needs of these services. However, for hydrogen technology to be accepted and implemented, other issues such as government policy, education, and employability must be addressed. Improvement in the performance and emissions of hydrogen as an alternative energy and fuel has grown in the last decade. However, other issues such as the storage and cost and the entire value chain require significant work for hydrogen to be implemented. The international community’s alternative renewable energy and hydrogen roadmaps can provide a long-term blueprint for developing the alternative energy industry. This will inform the private and public sectors so that the industry can adjust its plan accordingly.

A product configurator is a system providing questions and sets of possible answers about products with sets of possible answers. This paper proposes a new idea for a configurator in which information about products are expressed as a structured net of interconnected classes of different types. Classes hold information about assemblies, product structural links, and logical constraints. Some classes have references to technical data on a product data management (PDM) system. Such a system allows flexible representation of knowledge about product configurations for production of aviation equipment. Santrauka Gaminio konfigūratorius yra programinė sistema, pateikianti klausimus apie produktą su galimais pasirinkimų variantais. Šiame darbe pasiūlyta nauja konfigūratoriaus idėja ir pateiktas konfigūracijų aprašo modelis. Šis modelis buvo kuriamas taip, kad juo būtų galima aprašyti realius, dažnai tobulinamus ir sudėtingos sandaros gaminius. Modelyje informacija apie gaminį pateikiama kaip tarpusavyje sujungtų įvairių klasių tinklas. Modelio klasėse saugoma informacija apie gaminio junginius, komponentų ryšius ir loginius apribojimus. Siūlomas konfigūracijų aprašo modelis leidžia lanksčiai perteikti inžinerines žinias apie įvairių gaminių, tarp jų ir aviacijos reikmėms skirtų gaminių, variantus.
