Today air traffic at the airport is complicated including a significant increase in the volume of air transport, so aviation accidents are constantly occurring. Therefore, we should newly recognize importance of the Air Traffic Safety, the core values of the Air Traffic. The location of airport that is the basic infrastructure of the air traffic and the security of safety for facilities and equipments are more important than what you can. From this dimension, I analyze the step-by-step safety factors that are taken into account in the airport development projects from the construction or improvement of the airport within the current laws and institutions and give my opinion on the enhancement of safety in the design and construction of airport. The safety of air traffic, as well as airport, depends on location, development, design, construction, inspection and management of the airport including airport facilities because we have to carry out the national responsibility that prevents the risk of large social overhead capital for many and unspecified persons in modern society through legislation regarding intervention of specialists and locational criteria for aviation safety from the planning stage of airport development. In addition, well-defined installation standards of airports and air navigation facilities, the key points of the airport development phase, can ensure the safety of the airport and airport facilities. Of course, the installation standards of airport and air navigation facilities are based on the global standard due to the nature of air traffic. However, to prevent the chaos for the safety standards in design, construction, inspection of them and to ensure the aviation safety, the safety standards must be further subdivided in the course of domestic legislation. The criteria for installation of the Air Navigation facilities is regulated most specifically. However, to ensure the safety of the operation for Air Navigation Facilities, performance system proved suitable for the Safety of Air Navigation Facilities must change over from arbitrary restrictions to mandatory restrictions and be applied for foreign producers as well as domestic producers. Of course, negligence of pilots and defective aircraft maintenance lead to a large portion of the aviation accidents. However, I think that air traffic accidents can be reduced if the airport or airport facility is perfect enough to ensure the safety. Therefore, legal and institutional supplement to prioritize the aviation safety from the stage of airport development may be necessary.

Stable and reliable air traffic service is required for users (aircraft pilot, air traffic controller, airlines and public) through enhancing capability related to airport operation and continuously improving air navigation system. ASMS (air navigation service provider (ANSP) safety maturity survey) is to determine the level of management and safety requirement such as organization, risk, policy, process, training and environment in Air traffic service field. We designed and developed the survey (26 study areas of management part and 23 study areas of safety part) considering global best practices (Eurocontrol and FAA) and customizing domestic circumstances with quantitative level assessment regarding management and safety issue of Air navigation system. The survey enables the performance of Air navigation system to enhance and prevents from occurring accident or incident. Therefore, we provides best information with users as well as high quality Air traffic service.

3차원의 공간을 비행하는 항공기의 항행은 조종사가 직접 지상의 지형지물을 참조하며 비행하는 시각비행과 지상의 항행안전시설로부터 무선신호를 받아 비행하는 계기비행으로 구분되어 발전되었다. 현재 계기비행을 수행하기 위한 계기비행절차 수립에 기반이 되는 항행안전무선시설은 기존의 VOR(VHF Omni-directional Range), ILS(Instrument Landing System) 등의 지상기반 항행안전무선시설에서 GNSS (Global Navigation Satellite System)를 이용한 위성기반 항행으로 전환을 목표로 하고 있으며 항행체제 또한 기존의 Fix to Fix 항행체제에서 RNAV(Area Navigation) 체제로 전환되고 있는 추세이다. 계기비행절차는 항공기가 활주로를 이륙하여 항로로 진입하기 위한 계기출발절차(SID), 항로절차(Enroute), 항로에서 목적 공항의 지정된 활주로에 설정된 접근절차(Approach)로 인도하는 도착절차(STAR), 지정된 활주로에 착륙하기 위한 접근절차로 구분될 수 있으며 본문에서는 GNSS를 기반으로 하는 RNAV 절차(RNAVGNSS)에 대한 개괄적인 소개, 설계요건 및 RNAVGNSS 계기비행절차를 성공적으로 이행하기 위한 절차이행모델, RNAVGNSS 절차 수립에 중요하게 고려해야할 사항 등에 대하여 소개하도록 한다.

Airport-related laws restrict the installation of lights that obstruct the identification of airport lights or cause glare to pilots and controllers around the airport. However, with regard to the glare that lights give to the pilot or controller, it is only judged whether there is a limit based on a qualitative judgment, and a quantitative review has not been made. Therefore, in this study, visual disturbances that may occur to pilots and controllers due to large lighting facilities around airports during nighttime flight operation were quantitatively calculated and confirmed through disability glare, object recognition, and identification obstruction. And based on this study, it was suggested to supplement the related system to prevent the visual impairment of pilots and controllers caused by lighting facilities.

Navigational Aids Facilities help aircraft navigate by using wired communication, wireless communication, satellite, light, color and radio waves. Navigational Aids Facilities are used in all processes of aircraft operation, and if there is a problem with the facility, it may lead to delays in flight operation, cancellation of flights, and major airline accidents, resulting in enormous loss of life and property. In the management and operation of Navigational Aids Facilities, various outcomes will be brought about according to the advancement with the safety culture. The purpose of this study is to investigate the effect of advancement on safety culture in the operation of Navigational Aids facilities not only on members and customers, but also on benefits to bring to whole society. In this paper, the analysis results are presented using the structural equation model, and the meaning is presented in the conclusion.

Ground based augmentation system (GBAS) is a next generation radio navigation aids to support precision approach of aircraft. Recently, airports installing GBAS and providing GBAS service are increasing all over the world. For the first time in Korea, SLS-4000 which is the GBAS ground equipment of Honeywell had been installed at Gimpo International Airport in 2013, and evaluated its functionality and performance of through the ground testing. This paper introduces a ground test and evaluation criteria on the CAT-I GBAS system, and describes testing methods for GBAS ground testing of Gimpo International Airport. In addition, detail testing methods and analysis results on major five of 12 ground test items are described.

When a straight-in landing from an instrument approach using ILS or VOR/DME is not possible or desirable because of topographical reason or bad weather, a circling approach maneuver is initiated by the pilot to align the aircraft with a runway for landing. Visual contact with the runway is necessary while conducting a circle to land maneuver. This research is to develop a new warning system based on a convention marker system which alerts pilots to watch out for exceeding the circling approach area. The airborne system also uses the same receiver unit without any new installations. The objective of this research is to design and develop a Yagi antenna in a special form. The research includes computer simulations to determine the size of antenna radiation pattern and to compute an expected flight path in case of alarm to validate effectiveness of the system.

항공기반시설(공항, 기상 서비스, 항로 항행시설)에 대한 보안사고 대응을 위한 보안체계는 수립단계에서부터 착수하여 분석이 진행됨에 따라 세부적인 평가가 수행되어야하며, 시설변경이 발생하는 경우 변경된 시설에 대하여 재평가를 하여야 한다. 또한 항공기 운용과정에서 발생 가능한 각종 사고에 대한 사전 예방 및 정비를 위해서도 체계적인 보안성 평가가 필수적이다. 보안성 평가에는 계획(Plan), 활동(Do), 그리고 평가(Check), 조치(Action)업무가 네트워크 구조로 통합되어 적용되며, 과거의 사용 또는 경험에 따라 세분화된 보안성 평가 요구조건을 구분하여 적용한다. 특히 항공기반시설에 대한 보안성 입증과 안전한 운항을 보장하기 위하여 실시간 지원체계와 국가 차원에서 이를 관리하여야 한다. 이는 공공의 안전을 확보하기 위한 것으로서, 민간항공업체는 해당 법규, 표준서 및 지침 등에 따라 최소한의 보안성을 입증하여야 한다. 따라서 본 논문에서는 항공기반시설에 대한 보안사고 대응을 위한 보안체계를 위해 설정된 보안의 목표를 충족하고 있는지를 확인 평가하고, 분석 등을 고려하여 종합적인 보안성 평가기법을 적용할 수 있도록 하는 보안체계 네트워크 모델에 대해 제시하고자 한다.

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.
