Korea Aerospace Research Institute(KARI) has accomplished the planning study for setting up the mid-long term development plan of Goheung Aviation Test Center for the extensive use. In the future the aviation center will have a role of the complex center for the flight test, component test and R&D in Korea. KARI searches the legal requirements and informations for constructing the aviation test airfield in Goheung. Aviation law describes a lot of requirements to construct an airfield and the airfield also needs runway, equipments/facilities, obstacle limitation surfaces/distances, limitation altitudes and air space etc.. In this study the research results for the obstacle limitation Surface are mainly presented relating to the existing runway and the new large-scaled runway in Goheung.

In this paper, the critical requirement for obstacle awareness and avoidance is assessed with the compliance of the equivalent level of safety regulation, and then the collision avoidance sensor system is presented with the key design parameters for the requirement of the smart unmanned aerial vehicle in low-altitude flight. Based on the assessment of various sensors, small-sized radar sensor is selected for the suitable candidate due to the real-time range and range-rate acquisition capability of the stationary and moving aircraft even under all-weather environments. Through the performance analysis for the system requirement, the conceptual design result of radar sensor model is proposed with the range detection probability and collision avoidance mode is established based on the time-to-collision, which is analyzed by collision scenario.

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.

Although the domestic aviation industry has made rapid progress with the development of aircraft manufacturing and transportation technologies, aviation safety accidents continue to occur. The supervisory agency classifies hazards and risks based on risk-based aviation safety data, identifies safety trends for each air transportation operator, and conducts pre-inspections to prevent event and accidents. However, the human classification of data described in natural language format results in different results depending on knowledge, experience, and propensity, and it takes a considerable amount of time to understand and classify the meaning of the content. Therefore, in this journal, the fine-tuned KoBERT model was machine-learned over 5,000 data to predict the classification value of new data, showing 79.2% accuracy. In addition, some of the same result prediction and failed data for similar events were errors caused by human.

ICAO has recommended data-based aviation safety management and decision-making systems through Annex 19(Safety Management) and Doc 9859(Safety Management Manual), stressing that safety can be greatly improved by sharing aviation safety information throughout the industry. Accordingly, advanced aviation countries have built infrastructure to collect and analyze various aviation safety data in an integrated manner, and also tried to spread identified major safety issues across the industry. On the other hand, in Korea, each stakeholder collects, manages and analyzes safety data individually, so there is a limit to use them in integrative manner. In addition, the scope of using and sharing aviation safety information such as analysis result is also focused on safety management at the national government level, which is insufficient to be shared throughout the industry. Accordingly, the purpose of this study is to present a plan to share and utilize the domestic aviation safety information. To do this, we compare the current situation between FAA and domestic industry and suggest the improvement plans.

For predictive aviation safety management, the establishment of safety performance indicators to measure and manage the safety performance of service providers must be preceded. In particular, leading indicators are significant in that they play an important role in identifying and managing the causes of accident/incident in advance. However, the current safety performance indicators of the domestic aviation industry have limitations in that they focus on lagging indicators based on events that have already occurred. Therefore, the purpose of this study is to construct Korean leading indicators for preventive safety management. In addition, we verify the validity and importance of the indicators based on review of the experts and AHP analysis. This study is meaningful in that it can support the proactive safety management of the domestic aviation industry through the development of leading safety indicators, which have been relatively lacking in research.

Purpose: The purpose of this study is to present the preemptive prevention and improvement measures for aviation safety management by examining the current status of the aviation industry and the operation system of the aviation safety management system and identifying the shortcomings of the currently operating aviation safety management system. Method: A plan to improve aviation safety management was proposed through an analysis of recent incidents and accidents, current status of domestic laws, and analysis of overseas operating institutions and safety management systems. Result: Through the recent aircraft safety-related incidents, deficiencies of currently operating aviation safety management, and response cases of advanced countries in overseas aviation, improvement points in terms of management systems and laws and preventive aviation safety management plans were derived. Conclusion: The method for improving aviation safety management was presented based on the technique using data, and it should be materialized through additional related research.

Here I investigate what effects Operational Control Center(OCC)'s service quality may have on airline staff's job engagement. My analysis reveals that airline OCC's service quality has a meaningful effect on airline staff's service satisfaction, and that service satisfaction mediates a meaningful effect on staff's job engagement. It was suggested that improving OCC's service quality leads to higher staff's job engagement. Accordingly, I suggest methods of improving OCC's service quality. I find that the importance of contributing factors on OCC's service quality are as follows, in order of most to least important: professionalism, assurance, empathy, reliability, organizational culture, and responsiveness. The results of this study are relevant not only for airlines but also for government agencies such as the National Emergency Management Agency, the Korea Forest Service, the National Police Agency and the Korea Coast Guard that operate aircraft and must ensure aviation safety.

A Flight test is an important process that must be performed to maintain airworthiness in the aircraft lifecycle, including aircraft development and certification. Flight test can be conducted for the purpose of demonstrating or verifying compliance with the applicable standard. Results of the flight test air accident analysis confirm that it is caused by a combination of various factors as well as aircraft. The International Civil Aviation Organization recommends the establishment and implementation of a safety management system to prevent aircraft accidents, but it does not reflect the specificity of the flight test. As such, advanced countries are providing separate criteria to assist stakeholder in conducting flight test safety management. This study investigates and analyzes relevant regulations of advanced countries, in accordance with the construction of a national flight performance test site in Korea, and proposes government-level guidelines to help stakeholders develop their flight test operation manuals. The guidelines discuss topics such as organizational composition, safety and risk management, flight operation, personnel management, and administrative issues.
