Essence and Specific Features of State Regulation in the Field of Air Transport

The emphasis has been placed on the fact that an important direction in the development of air transport infrastructure is the increase of the efficiency of state regulation in the field of aviation transport. The author has analyzed the existing scientific approaches to the interpretation of the terms of “state regulation”, “state management”, “public management”, “public administration”, “legal regulation”; has revealed the peculiarities of their relationship. It has been argued that state regulation, state management and public administration are interrelated legal categories that differ in the object of management (regulation), purpose, forms and methods of implementation of management (regulatory) measures, as well as the range of entities authorized to implement these measures. It has been substantiated that state regulation is a process implemented by various branches of government by available legal means in order to ensure regulatory impact on the relevant social environment, focused on creating conditions for effective operation of entities and facilities in areas desirable and useful for certain industries. and the state in the whole.
 It has been established that the state regulation in the field of air transport should be understood as a purposeful process of implementing regulatory measures by the state in the person of authorized agencies in order to streamline social processes (public and legal relations between entities and objects of aviation), establishing general rules of conduct while transportation of passengers and cargoes by air, rendering other aviation services, designing, manufacture and service of air transport.
 It has been noted that the state regulation in the field of air transport is a system category, which consists of interdependent components, the combination of which allows to achieve the goals in a timely manner using the appropriate set of resources. Thus, the state regulation in the field of air transport is the system consisting of the following components: purpose and objectives; principles of regulation; object of regulation; subject of regulation; forms and methods of regulation; relations that arise during regulation.
 The peculiarities inherent in the state regulation in the field of air transport have been singled out.

Competing Climate Change Responses: Reflections on EU Unilateral Regulation of International Transport Emissions in Light of Multilateral Developments

In 2016, the International Civil Aviation Organization (ICAO) and International Maritime Organization (IMO) made important strides towards the regulation of emissions from international aviation and maritime transport. This was partially catalysed by the ‘ultimatum strategy’ of the European Union (EU), where the Union persistently threatened to take unilateral steps in the absence of multilateral action. As this article analyses, it appears that the Union is reluctant to relinquish its unilateral approach and align fully with both the ICAO Carbon Offsetting and Reduction Scheme and the IMO Global Data Collection Scheme. This raises questions under public international law as to the relationships between these competing measures. Amidst rising political pressures, this article considers the extent to which the unfolding multilateral policies of the ICAO and IMO may limit the regulatory competence of the EU. While the EU is an independent legal entity, it has been conferred far-reaching competences by its Member States who are themselves members of these other international organisations. Given the lack of clarity on clear hierarchical rules, an important role remains for the customary law of state jurisdiction in governing regulatory competence more generally. The final part of this article engages with recent discussions on the existence of an obligation to exercise jurisdictional self-restraint. It reflects on the tensions arising between respect for states’ regulatory autonomy and the prevention of ‘dangerous’ anthropogenic climate change.

Security of aircraft infrastructure objects: theoretical aspects

The article determines that the basis for effective activity for the protection of critical infrastructure facilities is the formation of a system of legislative definition of criteria for attribution to the critical infrastructure of the state of the relevant facilities, including aviation. The basis of legislative and organizational activity in this sense is the implementation of scientific research aimed at the formation of scientific and organizational security of aviation objects. It is stated that beyond the scope of modern research in aviation security and in the whole of all critical infrastructure objects there remain: theoretical clarification of the essence and correlation of such theoretical and applied categories of different types of security with regard to critical infrastructure and aviation transport objects. The reasons and conditions for the formation of security threats to the entire aviation infrastructure of Ukraine have not been properly investigated. The necessity of development of theoretical and applied and legal problems of safety of the objects of aviation transport of Ukraine is determined not only by the intervention in the activity of civil aviation, but also by the whole complex of conditions of normal activity of structures and subjects of business activity of objects of aviation infrastructure. The purpose of the article is to create on the basis of a series of articles a theoretical basis for organizational and legal security of objects of aviation transport infrastructure. The purpose of the article was implemented in a systematic approach to the study of existing problems in the security sphere of aviation infrastructure. The use of a set of general and specific research methods made it possible to determine the factors and content of the causes and conditions of the formation of threats to the security of all aviation transport infrastructure in Ukraine. This approach made it possible to conclude that the content of security of aviation infrastructure and economic entities located in their territory can be viewed from several positions: First - as conditions in which there is a complex system where the action of external factors and internal factors does not lead to the emergence of threats and negative objective and subjective negative processes. Secondly, as a condition of critical infrastructure - aviation, at which the risk of harming people or property is reduced to an acceptable level. Thirdly - as a type of activity of authorized structural units for creation of normative conditions for functioning of critical infrastructure objects - aviation transport. Taking into account the analysis of the practice, legislative and departmental regulations and opinions of scientists, a differentiated classification of security threats to aviation infrastructure objects is given, with determination of their impact on each element of the infrastructure.

Modeling of the transport and production complex in the growing of agricultural crops, taking into account the aviation component

Studies of the transport and technological process of growing crops revealed that it is a complex dynamic system. It is proved that the complexity of this system consists in the presence of a large number of heterogeneous subsystems, including transport, which is an important component for growing crops. Due to the system approach to the study of transport support of the crop growing process, it became possible to identify functional features of using ground and aviation vehicles. The properties of each stage of the growing process and involvement of certain types of vehicles are determined. The scheme of transport support of the crop growing process is developed and the influence of the aviation component at certain stages in the introduction of resource-saving No-till technology is determined. Experimental studies showed that the use of aviation transport contributes to the introduction of resource-saving No-till technology by minimizing the mechanical processing of sown areas, which reduces the anthropogenic load on the soil. The developed mathematical model for analyzing the use of the transport and production complex in growing crops allows making a rational choice of ground and aviation vehicles, depending on the parameters of technologies, types of crops. Thus, there is reason to argue that it is possible to make timely and reasonable management decisions in the organization and management of agricultural production in order to maximize profits

Effect of Different Arrangement on Thermal Runaway Characteristics of 18650 Lithium Ion Batteries Under the Typical Pressure in Civil Aviation Transportation

In order to investigate the thermal runaway mechanism of 18650 lithium ion batteries and the related hazards, an experimental platform for lithium ion battery fire and explosion is designed and built. The effects of different arrangements, including vertical 2 × 2 and vertical 4 × 1, and initial pressure (96 kPa and 61 kPa) on lithium ion battery thermal runaway are studied in this paper. Compared with the results of thermal runaway characteristics with two arrangements, a higher explosion pressure, a larger mass loss, more O2 consumption and more CO and CO2 production are observed of vertical 2 × 2 batteries due to the larger contact area between batteries. The explosion pressure of vertical 4 × 1 batteries decreases gradually with thermal runaway propagation. For vertical 2 × 2 batteries, the explosion pressure of battery C, D is about twice as large as battery A. The intensity of chemical reaction is more violent under 96 kPa which cause a lower onset temperature and a shorter onset time than that under 61 kPa. The thermal runaway propagation hazard can be reduced by decreasing the contact area between batteries. The results could provide useful guidance for the safety of lithium ion battery transportation in civil aviation.

Methodology of substantive fatigue life valuation of composite components of aero structure

The key features of the regulatory requirements for the fatigue life valuation of composite laminates were presented. With allowance for those requirements and through the use of the well-known patterns of residual strength degradation and stiffness degradation of layered composite materials over the course of fatigue cumulation, the fundamental principles of the methodology of substantive fatigue life valuation were created. They, in particular, can be used for the lower and upper wing paneling of the transport category of aircraft. It was indicated that it’s worth making the substantive valuation at the project definition stage of an aircraft, when the key parameters of the laminates are being determined: the type of layered composite materials, parameters of their placement, selection of analytical stresses, etc. As a conditional sample of the substantive fatigue life valuation of carbon fiber laminate, was presented to use as the AS4-PW 10/80/10 (8,84 mm thick) used in the capacity of the upper wing paneling of the transport aviation planes. The types of valuations were performed as follows: fatigue life prediction for the samples with free holes; fatigue life prediction for the samples with scarcely visible shock damages; fatigue life prediction for the samples with scarcely visible shock damages prior to reaching the standard residual strength degradation level; fatigue life prediction for the samples with scarcely visible shock damages prior to reaching the standard residual stiffness degradation level. The above valuations exposed significant distinctions between the received values for the different samples depending on the used prediction method. The analysis of the received values revealed the necessity of making the same substantive estimates for determination of the fatigue life valuation of composite components of aero structures with acceptable accuracy.

Discussion: clarification of the normative fixing of air traffic in domestic legislation, the role of Ukrainian aviation providers and airline operators in the «free sky» of Europe, the state of implementation of international standards and participation of Ukraine in international organizations. Transport, as an infrastructure industry, must be ahead of the pace in order to promote the country’s rapid economic and social development. The Ukrainian aviation transport system is on the path of integration with the European aviation transport system. The implementation of the task of gradual integration into European and world transport systems involves the implementation of European norms and standards in the air transport sphere, adherence to key international conventions and agreements, development of aviation infrastructure, international transport corridors and checkpoints, security and environmental friendliness. Ukraine’s intention to cooperate with the EU in order to improve the functioning of the trans-European transport networks is based on the relevant plan of the European Commission to extend the major trans-European transport axes to the territory of Ukraine. New agreements in this direction allow Ukraine to integrate into the Single European Aviation Market, but to achieve this goal it is necessary to harmonize the Ukrainian air transport network in accordance with European standards on the basis of not declarative but real implementation of state target programs in accordance with the system of international treaties. The aviation network to a single EU aviation network. Recommendations on the strategy and mechanisms of integration of Ukraine’s aviation network into a single EU transport system have been developed.

Impact of Carbon Tax Scheme and CO2 Control Technologies on Bangladesh Aviation Industry

Aviation transport action group reported that carbon dioxide (CO2 ) emission of airlines in 2017 was 859 million tons which is 2% of global emissions, (Akça, Z. 2018). It adds that the bank has calculated that “under the worst case ‘carbon intensive’ scenario, living standards will fall by 6.7% for Bangladesh by 2050”. This paper investigates how Bangladesh can respond to best optimize to the EU’s Aviation Carbon Tax Scheme proposed by the Stackelberg game model. The analytic result shows that the strategy “refusal of pay” is the best one which Bangladesh is taking step of. Numerical simulations specify a quantitative visual of the consequences found. The policy is found to be effectively not flying as much would reduce the CO2 emission and consequently, purchase of new aircraft, retrofitting and upgrade improvements on existing aircraft, latest designs in aircraft/engines, fuel efficiency standards and alternative fuels etc. reducing the overall emissions. The main contribution of this paper is to study a new international issue for developing country on aviation carbon tax and CO2 emissions policy suggestions for the aviation technology.

The result of the analysis of the tourism including aviation transport service multipliers of the 4 provinces indicates that the multipliers of output, income, value-added and employment in aviation transport service industry was very low, but the ‘-’ value of the multipliers value of 3 provinces was lower than the average multiplier value of all industries. Therefore, the economic impacts of the aviation transport service industry in Gyeongsangbuk-do is expected to increase in the future.

Reliability Analysis of the Air Transportation Network when Blocking Nodes and/or Connections Based on the Methods of Percolation Theory

The paper shows that to study the reliability and fault tolerance of air transportation networks, methods of percolation theory can be used, in which any aviation transport structure can be represented as a random non-planar, incompletely connected graph (nodes are airports, arcs are airlines). In the theory of percolation, one can consider the solution of the problems of finding the shares of blocked nodes and blocked connections for networks with various random and regular structures, in which they decompose into unconnected areas. The share of blocked nodes (in the node problem) or connections (in the connection problem), at which the conductivity between two arbitrarily selected network nodes disappears, is called the percolation (flow) threshold. For the same structure, the values of percolation thresholds for the bond problem and the node problem have different meanings. The percolation threshold value depends on the average number of connections per network node (density), and is a criterion for its reliability, i.e. determines the percentage of blocked nodes and/or communications that the network will lose the necessary level of performance ability. The dependence of the blocking threshold (percolation) on the network connection density can be expressed mathematically. Using a map of a real aviation transport network, it is possible to determine the average number of connections per one node and then calculate the threshold value of its predetermined reliability value. If the reliability threshold needs to be increased, then the necessary number of additional links can be calculated.
