The importance of the security management system for the aviation infrastructure cannot be overemphasized. What is especially important on the security management system for it is the assessment that is detaild and systematic. This article presents a framework based on a Hanulcha-type security management system model for a Information security of the Aviation infrastructure. This system checks, estimates and analyzes the goal of security with effect, especially in case of the security-accident on the aviation infrastructure because this system model gives the integrated security assessment method.

This paper aims to establish a reconfigurable flight simulation environment to conduct safety evaluation of various electric vertical take-off and landing (eVTOL) aircraft. Since the inceptor, aircraft dynamics model, and controller applied to each eVTOL aircraft are different, it was configured to be variable so that a simulation can be executed for each eVTOL aircraft. Test elements and performance indicators were set to perform safety evaluation of eVTOL aircraft. Ground auxiliary equipments were designed and implemented in a simulation environment according to test procedures for each test element. In addition, to analyze safety performance, a simulation flight data collection environment based on MATLAB/Simulink and a tool for safety performance analysis were implemented. Test flight and analysis were conducted in the implemented simulation environment in this paper. Finally, this study shows the environment was verified by confirming that it was performed normally.

With the recent rapid growth of the domestic and international unmanned aerial vehicle (UAV) market and the increasing importance of UAV operations in urban centers, such as UAMs, the safety management and regulatory framework for human life and property damage caused by UAV failures has been emphasized. In this study, we conducted a comparative analysis of risk-cost models that evaluate the risk of an operating area for safe UAM flight path planning, and identified the main limitations of each model to derive considerations for future model development. By providing a basic model for improving the safety of UAM operations, this study is expected to make an important contribution to technical improvements and policy decisions in the field of UAM flight path planning.

In developing avionics systems, safety analysis and evaluation specified in SAE ARP4761 (Methods and Guidelines for Civil Aviation System and Equipment Safety Assessment Process) are carried out to prevent air accidents. Safety analysis requires knowledge of the abnormal state of the system, not its normal state, and its interrelationships with other standards. Therefore, a tool that automatically outputs data which proves compliance with safety certification standards is required. In this study,In this study, Schematized the safety analysis procedure of the specification and studied the method of applying the safety analysis CAD tools to individual procedure. As an example study, ARP4761 analysis was performed on the wheel brake system (WBS) of the ARP4761 appendix.

The International Civil Aviation Organization (ICAO) has set up the Global Aviation Security Plan (GASeP), which urges member states to transition to more advanced security systems. This paper examines advanced aviation security policies and technologies at both domestic and international levels, and also investigates the underlying reasons for the challenges faced in establishing an advanced security system in the Republic of Korea. Based on this analysis, we propose effective strategies for deploying advanced security equipment at domestic airports, taking into consideration their respective classifications. Additionally, we identify the need for establishing new technological standards to introduce an advanced aviation security system, and provide evaluation criteria for the maintenance and management of technology to ensure the smooth operation of advanced security equipment.

In this study, we conducted a structural design and analysis of air intake of aircraft engine using composite materials. First, an investigation on structural design requirement of target structure was carried out. The distributed pressure load and acceleration condition was applied to structural design. To evaluate the structural design result, finite element analysis was carried out. The stress, deflection and buckling analysis for structural safety evaluation was performed. Finally, it was confirmed that the air intake through structural analysis is safety.

According to the State Safety Program (SSP) of the International Civil Aviation Organization (ICAO), it is essential to establish and manage Safety Performance Indicators (SPIs) which are used for monitoring the safety performance to achieve the national aviation safety goal. There have been enormous efforts to develop the framework of SPIs by considering the current status for each country. In case of Republic of Korea, however, there has been limited research and policy projects related to the framework for SPIs. Furthermore, Korea has used identical SPIs since the SSP was legislated in 2008. With this background, this research is, as part of strategy for the state level of SPI development, the study cases of advanced aviation countries for SPI development plans, such as the European Aviation Safety Agency (EASA) of the EU, the Civil Aviation Authority (CAA) of the UK, the Finish Transport Safety Agency (FTSA) of the Finland and the Federal Aviation Administration (FAA) of the U.S. The comparison between the foreign and domestic policies for SPI development strategies are provided in the conclusion of this study. The results and analyses of the case studies performed in this research will be helpful to provide some valuable development strategies for further SPI research in Korea.

This study suggests a method to enhance drone flight path planning and safety evaluation in urban areas using Computational Fluid Dynamics (CFD). As the use of drones in urban environments has been growing rapidly, there is a lack of established methods for path planning and safety evaluation, which leads to a risky approach relying on experimental methods. Therefore, this research takes into account the intricate 3D fluid dynamics between drones and buildings by employing CFD to quantitatively plan flight paths and evaluate their safety. To accomplish this, the study focuses on Gimcheon Innovation City as the target area and collects relevant terrain and building data, and selects prospective flight routes. CFD analysis is then carried out to gather essential data for flight simulations and safety assessment. The safety assessments are conducted based on environmental fluid dynamics when the drone operates along the proposed flight paths
