Analysis of the Current Situation, Problems and Countermeasures of Civil Aviation in China

After the founding of New China, some external competition and internal policy support led to the rapid development of civil aviation. In the process of development, some problems have also been found and solved. Up to now, China's civil aviation industry has a huge scale and is one of the most important industries in China, with a growth rate far exceeding the international level. However, due to the unstable international situation, airlines are under pressure due to the rise of oil prices and the reduction of passenger traffic, which also exposes many new problems. This paper describes four current problems of civil aviation. The problems are rough management and neglect of industrial structure, monopoly in the aviation oil and material supply sector, which is not conducive to reducing enterprise costs, excessive intervention in enterprise management, which hinders moderate competition in the air transport market, and relatively low economic efficiency of civil aviation. Solutions are also given to each of the above problems, which include industrial structure policy, industrial investment policy, anti-monopoly law and other related policies and legal systems.

NEW CHALLENGES IN THE OPERATION OF UNMANNED AERIAL VEHICLES. CHANGES IN LEGAL REGULATIONS REGARDING THE SAFETY OF UNMANNED AVIATION

The extremely dynamic development of civil aviation in recent years has simultaneously contributedto the growing popularity of unmanned aerial vehicles (UAVs), which have taken over air traffic inthe areas of protection and security of the population and, since the armed conflict in Ukraine, havealso been put to use as dual-use products in military operations. However, one must bear in mind alsousers who fly drones for private and recreational purposes. Such a rapid growth in interest caused thenecessity of introducing regulations that would enable their safe design, production, maintenanceand operation in the EU. Thanks to these requirements, the civil aviation authorities in the EU havemade every effort to create a solid legal framework for the operations of UAVs, keeping up with theirrapid technological development, minimizing accidents that involve flight participants and reducingthe risk of material damage or safety of bystanders present on the surface.The authors adopted the assumption that aviation safety regulations are excessively conservative.The first part of this hypothesis is not a revelation, the rule being that legal regulations are delayedin relation to the dynamics of technological progress in this field. The second is an open questionregarding the need for greater liberalization in the field of unmanned flights.

EXPERIMENTAL STUDY OF PHYSICAL-CHEMICAL PROPERTIES OF ADVANCED ALCOHOL-TO-JET FUELS

The paper presents an analytical review of technological processes of alternative jet fuel production from alcohols and experimental results on the study of its physical-chemical properties. State-of-the-art in the sphere of civil aviation development within the framework of sustainable development and minimization of transport’s negative impact on the environment is presented. The development and implementation of sustainable aviation fuels are considered the main measure for reaching carbon-neutral growth. Two technologies of alcohol-to-jet fuel production are considered, and possible feedstock and processing pathways are presented. Physical-chemical properties of two kinds of alcohol-to-jet fuels are studied experimentally, as well as the properties of conventional jet fuels blended with alternative ones. It is shown that the physical-chemical properties of jet fuels blended with alcohol-to-jet component containing aromatics are very close to conventional jet fuels. All of the studied fuel blends with alcohol-to-jet components completely satisfy the requirements of specifications. Basing on the received results it is expected that alcohol-to-jet component containing aromatics may be successfully used for blending with conventional jet fuel and used as a drop-in fuel.

Research on Evaluation System of Green Civil Aviation Development——Based on Air China

The establishment of a green civil aviation development system is an important measure to promote the long-term, healthy and stable development of the civil aviation industry. In order to objectively evaluate the development level of China’s civil aviation industry since the promulgation of the "Thirteenth Five-Year Plan for the Development of Civil Aviation in China", this article selects China International Airline data, comprehensively consider the concept and connotation of green civil aviation, select indicators from the four aspects of environmental protection, conservation, technology, and humanization, and establish a green civil aviation evaluation system. The TOPSI method and the entropy method are combined to obtain the weight of each indicator. Weights.

TA-LSTM: A Time and Attribute Aware LSTM for Deep Flight Track Clustering

The rapid development of civil aviation imposes an urgent need for efficient air traffic management. Flight track clustering is the premise and foundation of air traffic control. Flight track points compose time-series data with non-identical point- to-point intervals, and the effective latent representation of track data is key to the flight trajectory clustering. Long Short-Term Memory (LSTM) is an important and popular method to extract the features of trajectory time-series data. However, LSTM ignores the irregular time intervals between track points and fails to effectively distinguish the importance of different attributes at each track point during feature extraction. In addition, the existing methods based on LSTM either ignore the distinct impacts of different attributes at each track point or simply assume that the influences of the previous track points on the subsequent ones decrease with time. In this paper, we propose a flight trajectory feature extraction unit called TA-LSTM (Time and Attribute Aware Long Short- Term Memory) and a flight track clustering model based on TA- LSTM. The flight track clustering model consists of a feature extraction layer and a clustering layer. The feature extraction layer adopts TA-LSTM to obtain the latent representation of flight tracks, which adds a time control gate and an attribute control gate to the standard LSTM unit. The time control gate manipulates the action of each track point on subsequent points to obtain the characteristics of irregular time intervals. The attribute control gat enables LSTM to capture the impact of different attributes on the flight track features at various points. The clustering layer takes the latent representation of flight tracks as the input to obtain the clustering results. The clustering model updates the parameters of TA-LSTM and the cluster centers by minimizing the Kullback-Leibler (K-L) divergence. We conduct experiments using Automatic Dependent Surveillance-Broadcast track data provided by VariFlight. In comparison with popular and state-of-the-art methods, the proposed method obtains superior pe formance in three widely used evaluation metrics, i.e., Silhouette Coefficient, Calinski-Harabaz index and Davies-Bouldin index.

HISTORICAL CIRCLE OF THE FACULTY OF GROUND STRUCTURES AND AIRFIELDS OF THE NATIONAL AVIATION UNIVERSITY

The article is devoted to the genesis of the scientific and educational school for training specialists in the design, construction and operation of airfields at the National Aviation University. The historical periods of formation and development of educational technologies and educational management are revealed. It is noted that the training of specialists in the design, construction and operation of airfields and ground facilities, including airports, was started at the National Aviation University in 1933. The rapid development of civil aviation in the post-war period led to the establishment of the Faculty of Airports in 1968 as part of the university. During this period, the educational and scientific activity of the faculty is characterized by the formation of a holistic model of educational training of specialists in ground maintenance of civil aviation and operation of airfields. Under the influence of the market conditions of the socio-economic development of the state, a period of transformations and searches for a model of educational activity began in 2002, which culminated in the creation of the Faculty of Architecture, Construction and Design in 2018, a significant decline in the interest of entrants to educational training under the airfield operation program. From 2021, the search for a balance between the specialties of the faculty and a change in the priorities of educational training will take place in favor of restoring the role of the National Aviation University in the development of airfield construction and airfield operation.

Challenges of sustainable development and safety of world civil aviation in the conditions of globalization

The UN's global strategic document is the 2030 Agenda for Sustainable Development. It is an action plan aimed at ensuring global sustainable development in economic, social and environmental directions, which ensures that no UN member country is left behind. The 17 Sustainable Development Goals in the 2030 Agenda can be used as guidelines for the coordinated development of UN member states. Every year, the number of countries that also connect aviation to a wider range of UN Sustainable Development Goals, such as 4, 8, 9, 11, 13, 14, 16 and 17, is increasing. At the same time, the achievement of these goals requires working out the theoretical foundations of strategic management of global civil aviation safety. The issue of aviation safety is one of the top priority challenges from the first day of flights. Years passed, technology, avionics, engines, navigation aids changed and developed, but the problem did not lose its relevance. ICAO's purpose: to ensure the safe and orderly development of all aspects of international civil aviation. ICAO develops Standards and Recommended Practices. They are set out in 19 Annexes to the Convention on International Civil Aviation. ICAO's new strategies are the basis for further sustainable development of global civil aviation.

Aviation and Airspace Management under Rough Set Theory

With the development of aviation industry, a series of problems have appeared in aviation and airspace, among which the most prominent problem is the congestion of aviation and airspace. Airspace congestion has become a major problem in the development of civil aviation in China. Especially in the central and eastern regions of China, airspace congestion is becoming more and more serious. To better solve the problem of airspace congestion, rough set theory and the Fuzzy C-means (FCM) model are first analyzed. By analyzing the temporal and spatial characteristics of traffic congestion in the control sector, a multisector traffic congestion identification model is established based on radar track data. Four multisector congestion characteristics including equivalent traffic volume, proximity, saturation, and traffic density are established. FCM and rough set theory are used to classify and identify sector congestion. Finally, the model based on FCM-rough set theory is compared with other methods based on the data of the regional control sector in northwest China. The experimental results show that the congestion recognition rate of the model is 92.6%, 93.5%, and 94.2%, and the congestion misjudgment rate is 1.5%, 1.2%, and 1.3%, respectively. Hence, the multisector congestion recognition model has a high recognition rate and a low misjudgment rate, and the overall discrimination result is relatively stable. By comparing the proposed method with other methods, it is concluded that the recognition accuracy of the model based on FCM theory is superior to other methods. In summary, the congestion situation of the sector is affected by a variety of macro- and micro-characteristics of the sector, and the congestion identification model is feasible and efficient. Multisector traffic congestion identification has certain application value for airspace planning, air traffic control-assisted decision making, and air traffic flow management. This work can optimize the aviation and airspace management system and provide relevant suggestions for the study of aviation and airspace congestion.

Decoupling analysis on China's civil aviation carbon emissions from transportation revenue: A three-dimension decomposition framework

With the rapid development of China's civil aviation, carbon emissions have brought severe environmental problems. Understanding the internal dynamic relationship between carbon emission and air transportation development is conducive for the industry to realize green development more effectively. Based on the Tapio decoupling theory, this study investigated the decoupling status between civil aviation carbon dioxide (CO2) emissions and transportation revenue. A three-dimension decomposition model was constructed and applied to further explore the influencing factors of various decoupling status. The empirical study resulted in three key findings. Firstly, there is still much room for efficiency improvement in civil aviation overall transportation process. Compared with the external economic environment and the production process, the improvement of civil aviation operation process needs to be further strengthened. Secondly, the civil aviation carbon emission decoupling status was dominated by negative decoupling. The growth of air transportation revenue still deeply depends on the fossil fuel consumption. Thirdly, the decline of potential energy intensity significantly propels the decoupling progress of China's civil aviation; meanwhile, external economic environment and potential transportation intensity are key inhibitors of the decoupling development.

Construction of Internal and External Environmental Management System of Human Resources in Civil Aviation Institutions Based on System Dynamics

The basic investment needed for the development of civil aviation transportation has a long period, large investment, and strong exclusivity. The quantity of fixed investment should match the scale of the stage of civil aviation development. Scientific demand forecasting is the basis of reasonable planning of civil aviation infrastructure and fleet construction. Based on the principle of system dynamics, this paper analyzes the internal and external influencing factors of air passenger transport demand, and establishes a system dynamics model between civil aviation passenger transport market demand forecast and human resource management system. Using the model, based on the level of economic and social development, it is predicted that the demand for air passenger transport will reach 1 billion passengers around 2024. The demand system dynamics model of civil aviation passenger transport market has universal applicability and long-term effectiveness for the derived long-term demand forecast and analysis of civil aviation transportation. The results show that based on the derivative characteristics of air transport demand, the demand influencing factors of air passenger transport market can be divided into external and internal factors, which are mainly affected by population, economy, residents’ consumption level, air-rail competition, and other factors. Internal factors mainly include ticket price and service level.

Sliding window change point detection based dynamic network model inference framework for airport ground service process

With the rapid development of civil aviation, the number of airport flights is continually increasing and the low efficiency of flight ground services has become one of the main reasons for flight delays. Obtaining a precise description of the flight ground service network is of great importance to the efficient and safe operation of airports. In this study, we constructed a dynamic network model inference framework based on sliding window change point detection. First, a change point detection algorithm was proposed to divide all time points into two parts, namely, a set of possible change points and a set of completely impossible change points, which greatly reduces the true change point search space. Then, two novel change point elimination judgment rules were designed and combined with the structure learning algorithm to achieve iterative optimization within the possible change point sets, obtain the final true change points, and realize precise dynamic network inference. Based on the experimental results, our proposed method has a higher accuracy and computational efficiency than the state-of-the-art methods, and it can be easily adapted to large-scale datasets. Finally, the proposed model was used in an airport flight ground service analysis. Each day was divided into four stages and the potential dependence relationships between different nodes in each stage were accurately determined. Thus, the model has great practical significance for the accurate scheduling and efficient operation of airport ground services.
