Currently, the domestic UAS technology is lagging behind the leading countries in terms of both advanced technology and industrial competitiveness, but it cannot avoid the global efforts of integrating UAS into existing manned aviation system and applying them to industries. UAS is a relatively new system to existing aviation world, but ICAO is making a great effort to help Contracting States and the aviation industries to better understand and promote UAV systems. In particular, the UAS is classified as RPAS and other UAS, leading to the standardization work for integrating the RPAS into the manned aviation in the near future. For this purpose, ICAO has been promoting the standardization for the global operation of the RPAS, and in this study, it has been carrying out the study on the strategy to establish the domestic RPAS certification system including the ICAO standardization activities. This paper analyzes the domestic and international regulatory frameworks for RPAS and presents a strategy for building the domestic RPAS certification system.

The penalty clauses of 'Aviation Act' and 'Aviation Safety and Security Act' going into effect now were legislated because the aviation safety is being more influenced by the aviation safety system compared to the ground or maritime transportation and it is possible the aircraft can harm to people and wealth located in the ground as well as threaten the safety of the passengers and crew on board when it is the target of crimes. However, analyzing the current acts, applicable objects and behavioral requirements of some provisions are too general, and they are providing severely high penalties in many clauses without separating applicable objects and behavioral requirements. In addition, there are some critical legislative defects and there is a problem in terms of law-applicable area in the legal system. It is inferred that these legislative problems of the criminal special-law related to the aviation were caused by following reasons; first, aviation security experts or policy-makers than criminal law experts attended more actively in the enactment process, second, the communication among specialist groups were not accomplished well enough.

Although continuous passenger injuries and physical damages are repeated due to the unexpected aviation turbulence encountered during operations, there is still exist the limitation for preventing recurrence of similar events because the lack of real-time information and delay in technological developments regarding various operating conditions and variable weather phenomena. The purpose of this study is to compare and analyze the meteorological data of the aviation turbulence occurred and actual flight data extracted from the Quick Access Recorder(QAR) to provide some precursors that the pilot can identify aviation turbulence early by referring thru the flight instrumentation indications. The case applied for this study was recent event, a scheduled flight from Incheon Airport, Korea to Narita Airport, Japan that suddenly encountered turbulence at an altitude of approximately 14,000 feet during approach. According to the Korea Meteorological Administration(KMA)'s Regional Data Assessment and Prediction System(RDAPS) data, it was observed that the strong amount of vorticity in the rear area of jet stream, which existed near Mount Fuji at that time. The QAR data analysis shows significant changes in the aircraft's parameters such as Pitch and Roll angle, Static Air Temperature(SAT), and wind speed and direction in tens of seconds to minutes before encounter the turbulence. If the accumulate reliability of the data in addition and verification of various parameters with continuous analysis of additional cases, it can be the precursors for the pilot's effective and pre-emptive action and conservative prevention measures against aviation turbulence to reduce subsequent passenger injuries in the aviation operations.

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.

In the face of the unprecedented crisis of coronavirus disease (COVID-19), the aviation and tourism industry fell without help. The bigger problem is that a crisis like COVID-19 can always come back. A new variant of the virus that is more powerful than COVID-19 may emerge, and another crisis such as a massive war may come. In addition, there may be an unexpected large-scale crisis that could shake the survival of the aviation and tourism industry in place. At that time, the aviation and tourism industry should not be pushed into a survival crisis defenselessly. Taking the experience of the crisis caused by COVID-19 as a crucial lesson, sufficient protection measures should be prepared in advance, and within the protection measures, the overall capabilities of the aviation and tourism industry should be preserved, and preparation should be made for the aftermath of the crisis. There is a need to establish a support system in which financial resources that can be used in crisis situation can be secured in advance, and various support measures can be implemented as effectively as possible by using the secured financial resources. Regarding the preparation for financial resources, various fundraising, insurance, and compensation for losses by the state or local government may be considered as a priority, and in addition, there is a need to continuously consider ways to prepare additional financial resources. On the other hand, in terms of system construction, establishment of the system inside the aviation and tourism industry may need to be considered first, but the improvement of related laws and systems needs to be more actively discussed and related legislation needs to be actively promoted.

As seen in the case of the Boeing 737 Max accident, the proportion of aircraft software is rapidly increasing. However, it is vulnerable to safety issues. In case of domestic aircraft software, to operate a Light Unmanned Aerial Vehicle (LUAV) less than an empty weight of 150 kg, safety certification is required for an Ultra-Light Vehicle (ULV). However, software certification procedure is not included. Since the use of LUAVs has increased recently, software verification is required. This paper proposed a checklist of LUAV software that could be applied to LUAV referring DO-178C, an aviation software certification standard. A case study of applying the proposed checklist to the Model-based Development-based Helicopter Flight Control Computer (FCC) project currently used by domestic and foreign advanced companies and institutions was conducted.

Domestic and foreign aviation industries showed steep growth along with rapid increase in aviation demand, but the industries got directly hit by COVID-19. Now, with the recovery of daily life, aviation demand is gradually increasing, too. However, the risk of aviation accidents also increases proportionally to the increasing demand for aviation. Although it is a point that safety management needs to be actively conducted to prevent safety accidents resulted from the growth of aviation industries, research on safety culture and organizations is not sufficiently done in terms of the depth and scope of it despite the importance of the discussion. Studies in various areas have reported that an organization's safety culture forms the group's safety atmosphere and then results in the workers' safety behavior. Accordingly, this study examined the effects of safety culture in an organization on the safety behavior of its members who are aircraft maintenance technicians. The results of this research can be summed up as follows: first, it has been found that the roles of the person in charge grounded on clear goals and guidelines for the organization's safety policy influence the technicians' attitudes. Second, the important factor in the technicians' safety observance is that the attitude to follow safety rules when performing aviation maintenance raises their awareness of safety, for instance, following standard operation procedures or wearing personal equipment for protection. Third, their attitudes have positive effects on safety participation, and consequently, their intention to comply with safety rules is shown as an active action to achieve the ultimate goal of safety behavior.

To manage State Safety Program (SSP) in a more integrative and proactive manner, an aviation safety authority of the state shall detect and assess the risk of emerging or hidden safety hazards before they provoke accidents or incidents(ICAO, 2018). In case of South Korea, safety risk assessment is conducted by calculating the likelihood and severity of the hazard following ICAO's safety management manual. It is reasonable to extract the safety risk likelihood by calculating the number of occurrence caused by the hazard. However, it is ambiguous to assess the safety risk severity defined as the extent of harm that might be expected to occur as a consequence of the identified hazard. In this paper, a safety risk assessment method which quantitatively calculates the risk of hazard using aviation safety data(i.e. aviation safety mandatory report, etc.) is proposed. By utilizing the proposed method, the existing process that safety risk is being subjectively assessed by safety inspectors can be supplemented. So that essential aviation safety policy decision making can be accomplished by the accurate result of safety risk assessment.
