This study is to review the problem concerned with aviation safety in Korea and suggest the solution to secure the aviation safety, in respect of regulation. At first, the definition and characteristics of aviation safety are studied, and then the endeavor for the aviation safety of ICAO and FAA are reviewed. All the fields of aviation safety area are included in the scope of this study; airworthiness in aircraft production and maintenance, flight operation, airport operation and air traffic control. The level of safety can be estimated by the frequency of accidents and seriousness. The causes of air accidents can be summarized as five factors; human factor, traffic environment. aircraft, weather, and unexpected incident. The activities to protect accidents are also can be summarized as five areas; man, machine, medium, mission and management. ICAO established the standards and recommends for the aviation safety, and adopted strategic action plan for 21st century. Federal Aviation Administration of USA also contributes for the aviation safety of world wide. Nowadays, ICAO and FAA tries to coordinate each other to set up efficient and effective ways for the aviation safety. ICAO developed safety oversight manual and FAA developed model regulations, individually. However, there has been trials to merge the results of each institute's studies. The direction of this endeavor is to meet the new environment related to globalization of air transport industry. It is necessary for our government to improve the aviation safety regulation system to address the new wave of aviation safety system pursued by international organization. A systematic and comprehensive measure should be devised by cooperation of all the related field and area.

An empirical analysis was conducted on the workload of helicopter pilots flying in high-risk flight environments such as ground obstacles and weather effects at low altitudes. To evaluate the workload, an independent sample t-test was performed using the NASA-TLX evaluation method most suitable for the aviation field, and the workload score was calculated by applying the analytical stratification method (AHP) to compare and analyze private and commercial pilots. There is a significant difference in mean between private and commercial pilots and the result of work load was obtained over 70%. This paper studied the 'surprise and startle effect' on the helicopter field for the first time. In the future, it is intended to contribute to the safe operation of helicopters by presenting a method for effective safety management by utilizing it in the field of education and training for helicopter pilots and providing basic data for preventing accidents caused by human error.

In order to enhance the aviation industry in Korea, many strategies have been published by some researchers as well as the government. However, considering the constrained conditions in real, since the ranking of their importance has not determined yet, they are difficult to be implemented by decision makers. Therefore, in terms of their demand for deciding the significance of strategies, the evaluation model of this paper was developed. In this study, the Cross-impact Hierarchy Process(CHP), an linked model of both the Analytic Hierarchy Process(AHP) and Cross Impact Analysis(CIA), was selected as the best model. That is because the strategies are not independent from each other, and one strategy can affect the others depending on its realization, which can be considered in CHP. To achieve our objective, at first, the strategies were categorized and arranged according to the evaluation structure. Secondly, the parameters such as conditional probability and weights were estimated from the survey conducted by 16 experts in the aviation field. Lastly, the result of the assessment were discussed, and further studies were suggested.

Aviation safety issues have drawn much attention from the international community due to the growing demand for air travel. Although it is a widely accepted fact that human-related factors are closely linked to aviation safety, there is lack of understanding what roles those factors play in aviation, in the field of air traffic control in particular. It has been reported that the role of air traffic controllers significantly affects air safety. This review will discuss cognitive aspects of expertise in air traffic control including time perception, working memory, reasoning, perception, attention, scanning/vigilance, decision making, and planning with examples of how each aspect can be dealt with in performing air traffic control duties. The relevant studies in psychology have also been briefly reviewed in the interest of enhancing understanding of characteristics of air traffic control tasks and the related human factors. This review concludes with a call for more in-depth research into cognitive factors in air traffic control.

Many organizations apply reactive safety management to prevent the same or similar types of accidents by through investigation and analysis of the accident cases. Although research on investigation techniques has contributed a lot to the objective results of safety accidents and the preparation of countermeasures, many accident investigation techniques currently in use treat accidents from a linear perspective, revealing limitations in reflecting current systems dominated by complexity and uncertainty. In order to overcome these limitations, this study will review recent studies and concepts from a system safety perspective and predict future research trends through a case analysis of aviation accident. The models used in the analysis are STAMP, HFACS, and FRAM, and the characteristics of each technique are presented so that analysts who perform related tasks in the field can refer to them.

In order to determine the possibility of using NDGPS signals for flight operations, in-flight measurements of signals transmitted from various ground reference stations(RS) were conducted along the air routes of South Korea. Signal strength and signal to noise ratio(SNR) data were collected along domestic flight routes and recorded with time. By using three-dimensional geographical position data of the aircraft, signal strength data of en-route position were calculated and used to obtain scatter-plot of signal strength. These results were used to outline the effective coverage and field strength hemispheres of the selected DGPS signals.

Magnitudes of Magnetic field, Electronic field and Microwave was measured during the each stage of flight in the airline operation. The results was much higher than the safety standard and proved to be serious to the cockpit crews on their duty. We also identified that the magnitude of electronic field was much decreased by all three kinds of microwave protection equipments. We recommend that the cockpit crew have to wear the protection clothes to reduce the hazardous effects on their duty and the aircraft manufacturers have to consider the microwave-reduced cockpit in the initial stage of aircraft design.
