In this paper we firstly review the developmental stages of the Chinese civil aviation industry since 1949 and the background history of the Chinese Civil Aviation Law of 1996. We secondly analyzed the main terms and conditions about the Chinese civil aviation law and pointed out several problematic issues in view of the development of the Chinese aviation industry. Current civil aviation law in China has been in effect for the last 12 years. In these periods, Chinese civil aviation industry has developed in a high speed and great changes have occurred in its market environments. Thus, some of the terms and conditions in current civil aviation law in China have become outdated and unsuitable for the current developmental stage of the Chinese civil aviation industry. Therefore, we proposed some directions of the future amending of the Chinese Civil Aviation Law.

In this paper, a capacitors energy strategy based Cascaded H-bridge Converter (CHBC) for steady DC link voltage is proposed, which allow the CHBC to work while DC power fails. The topology of the CHBC is analyzed to construct the proposed strategy. The capacitors energy strategy is deduced based on the principle that the DC link voltage should be steady, the switch state should be smooth and the switch frequency should be normal. Experiments based on a three-module prototype, including static experiment, start experiment and step change experiment, proves the correctness of the strategy. They also verified the excellent fault tolerance ability and good dynamic performance of the proposed strategy.

The air transportation industry in Korea has grown very fast in aspect of the transportation scale as much as entering within the tenth in the world. However, as compared with the air transportation industry, the civil aviation pilots training has been performed at very low level in quantity and quality because of the high cost of pilots training, nation security, limited airspace use and falling behind of the science technology in relation to the aviation industry. In result, the number of airline pilots became lower than actual demands of both airlines, KAL and ASIANA. This produced many foreign captains employed, airline pilots overloaded and finally affected flight safety. In this paper, it was studied the actual reality and problems of civil aviation pilots training and presented the encouraging policies for civil aviation pilots training in Korea.

Civil aviation cybersecurity challenges are global in nature and must be addressed using global best practices and the combined efforts of all stakeholders. This requires the development of comprehensive international strategies and detailed plans for their implementation, with appropriate resources. It is important to build such strategies on a common methodology that can be applied to civil aviation and other interrelated critical infrastructure sectors. The goal of the study was to determine the methodological basis for developing an international civil aviation cybersecurity strategy, taking into account existing experience in strategic planning at the level of international specialized organizations. The research was conducted using general scientific and theoretical research methods: observation, description, formalization, analysis, synthesis, generalization, explanation As a result of the study, it was established the specifics of the approach to formulating strategic goals in civil aviation cybersecurity programs in the documents of intergovernmental and international non-governmental organizations in the aviation sphere, generally based on a comprehensive vision of cybersecurity management. A comparative analysis of strategic priorities, objectives, and planned activities for their implementation revealed common characteristics based on a single methodological sense of cybersecurity as a symbiosis of five components: human capacity, processes, technologies, communications, and its regulatory support. It was found that additional branching and detailing of priority areas in the strategic documents of international civil aviation organizations (by the example of Cybersecurity Strategy and Cybersecurity Action Plan) does not always contribute to compliance with a unified methodological framework. It is argued that to develop an international civil aviation cybersecurity strategy, it is advisable to use the methodological basis of the Cyber Security Index.

Crashworthiness design and certification have been and will continue to be the main concern in aviation safety. The effects of roll angles on fuselage section crashworthiness for typical civil transport category aircrafts were investigated. A fuselage section with waved-plates under cargo floor is suggested, and the finite element model of fuselage section is developed to simulate drop test subjected to 7 m/s impact velocity under conditions of 0-deg, 5-deg, 10-deg and 15-deg roll angles, respectively. A comparative analysis of failure modes, acceleration responses, and energy absorption of fuselage section under various conditions are given. The results show that the change of roll angles will significantly affect fuselage deformation, seat peak overloads, and energy absorption. The crashworthiness capability of aircraft can be effectively improved by choosing appropriate landing way.

The purpose of this study is to review the changes in the aviation safety management system, how that system has evolved and what forces caused these changes to take place. Also included is an examination of the development process of the aviation safety management system in view of the new institutionalism, identifying the patterns of change. Based on the results of this study, I propose policy methods to design a desirable civil aviation safety system with a view toward raising the safety standards in the Korean civil aviation community. The major analysis variables are as follows: first, aviation accidents caused by external factors and international standards as independent variables; second, environmental changes and political processes affecting aviation safety management system as major mediating variables; and third, the aviation safety management legal system, the aviation safety management organizations and an expert participation system as dependent variables. The institutional changes and continuance of the aviation safety management system show that when specific circumstances arise, the continuance lasts depending on the path dependency, and in a certain circumstance, when immanent changing factors reach a critical point, the system suddenly changes by a punctuated equilibrium, which are all included in this study.

As a sophisticated detection technology, LIDAR has been widely employed to probe low-altitude windshear. Due to the drawbacks of the traditional ramp algorithm, the alarm accuracy of the LIDAR has not been satisfactory. Aiming at settling this matter, a novel method is proposed on the basis of improved signal smoothing and second windshear detection, which essentially acts as a combination of ramp algorithm and segmentation approach, involving the human factor as well as signal fluctuations. Experiments on the real and artificial signals verify our approach.

중국 민용항공법은 1995년에 처음으로 제정되고 나서 20여년 사이에 처음으로 전면적인 개정이 이뤄졌다. 이번 개정은 20여년 동안의 민용항공법 시행 실천경험에 비추어, 국내외 민용항공법의 입법과 민용항공 국제협약의 최신성과를 참조하고 항공안전에 대한 감독과 관리를 강화하고 소비자 권익을 보호함으로써 민용항공활동이 안전하고 질서 있게 발전하고 민용항공활동에 관련되는 여러 당사자의 이익의 균형을 도모하고 민용항공사업 발전을 촉진함으로써 중국을 민용항공 강대국으로 건설하는데 유력한 법적 보장을 마련하는 것을 지도사상으로 하고 있다. 이번 개정안에서는 항공안전을 강화하기 위하여 항공제품의 안정생산 각 단계에서의 담당자의 책임과 관련 부문의 관리책임을 명확히 하였고, 공공항공운송기업의 항공기 추적능력의 설립을 강화하였으며 위험물품운송에 대한 법적인 규제를 강화하였다. 또한 이번 개정안에서는 안보를 강화하는 업무원칙, 관련 기관의 직책과 불법소란행위 등을 명확히 하고 이를 위반하는 경우 부담해야 하는 법적책임을 상당히 강화하였다. 국가에서는 민용항공산업의 발전을 지지한다는 원칙하에 민용항공산업의 발전을 위하여 자금투자를 위한 법적 보장을 마련하고 각급 정부에서 공항건설과 발전을 촉진하는데 있어서의 직책을 명확히 하였으며, 정부의 관리와 통제가 과도하여 민용항공산업의 발전과 자원배치에 불리한 심사비준제도를 등록제도로 변경함으로써 정부당국의 권한을 줄이고 공공운송기업의 설립조건을 조정하는 등 일련의 통용항공산업의 발전을 위하여 법적인 제도를 개혁하였다. 이외에도 소비자 권익을 보호하는 획기적인 규정들이 새로 개정되었는데 항공운송총조건을 운송계약의 구성부분임을 명확히 밝히고 항공기 지연에 관한 항공사의 책임을 묻는 지도원칙을 확립하고 1999년 몬트리올협약에 따라 항공운송인의 배상책임한도액과 배상책임제도를 조정하였다. 이외에도 항공기사고 발생시 지면제3자에 대한 손해배상에 대한 리스크를 줄이기 위하여 항공운송인의 보험가입을 적극적으로 격려하는 규정을 마련하였다. 동 개정안은 비록 현행 민용항공법상의 미비점을 상당부분 보완하였지만 국내항공운송과 국제항공운송인의 책임을 차별화하여 별도의 규정을 두었다는 점, 항공기내에서의 핸드폰 사용 등을 소란행위로 포함시켰다는 점으로 보아 항공안전을 이유로 지나치게 여객의 권익을 제한한 것은 아닌지, 항공기 산업발전을 위한 정부의 격려정책이 중국이 가입한 WTO 협정에 위배될 소지를 남겼다는 등 부분은 향후 더 검토하여 신중하게 개정안에 반영해야 할 사안이다. 현재 민용항공법 개정안은 의견수렴을 거친 상태이다. 그러나 전국인민대표대회 상무위원회 2016년 10월 31일부터 11월 7일 까지의 심사 및 의사결정 일정표를 보면 민용항공법 초안이 포함되지 않았다. 따라서 2017년에 민용항공법 개정초안이 인민대표대회 상무위원회 심사 및 의견결정 일정에 포함되는 것이 급선무 일 것이며 일단 동 일정에 포함되어야 만이 법 개정이 신속하고 효과적으로 진척이 될 수 있다. 따라서 그 이전까지는 의견의 불일치가 많은 조항부터 전문가들과 사회공중의 광범위한 논의를 진행하게 될 것이다.
