An aircraft collision accident is a disaster that causes great losses of inventories and lives. Though a collision avoidance warning function is provided automatically to pilots in the aircrafts by the enhancement of the aircraft capability, achieving fast decision-making to escape a collision situation is a complex and dangerous work for pilots. If an in-flight collision situation is controlled by the air traffic control system which monitors all airplanes in the air, it would be more efficient to prevent in-flight collisions because it can handle the emergency before the pilot's action. In this paper, we develop the collision avoidance warning function in the air traffic control system. Specifically, we design and implement the five stages of the collision avoidance function, and propose a visualization method which could effectively provide the operators with the trajectories and altitudes of the aircrafts in a collision situation. By developing an in-flight collision warning function in the air traffic control system that visualizes flight patterns through the state transition data of in-flight aircrafts on the flight path lines, it can effectively prevent in-flight collisions with traffic alerts. The developed function allows operators to effectively select and control the aircraft in a collision situation by providing the operators with the expected collision time, the relative distance, and the relative altitude while assessing the level of alert, and visualizing the alert information which includes the Attention-Warning-Alert phase via embodying the TCAS standard. With the developed function the air traffic control system could sense an in-flight collision situation before the pilot's decision-making moment.

전 세계 항공교통량은 1977년 이래로 매 15년 간격으로 2배씩 성장하는 비약적인 증가세를 보임에 따라 국내·외 항공교통관제 서비스와 항행안전시설 운영관리 체계 및 현황 검토를 통한 관리 운영의 효율성 등을 진단하여 기능을 통합한 항공교통관제기관의 설립 타당성을 제시하고 미래 항공운송 환경에 대비하여 선진화된 항공교통관제서비스의 제공을 위한 독립 전담기관 운영체계의 수립이 필요하다. 특히, 2021년에는 국제정책·기준 등 항행환경 변화를 적극 반영하여 항공교통을 안전하고 효율적으로 처리하기 위한 운영, 시설, 제도 등에 대한 맞춤형 종합계획인 국가항행계획(NARAE; national ATM reformation and enhancement)이 수립됨에 따라 더욱 항공교통관제기관의 역할이 중요하게 되어 관제 및 항행 운영체계의 향상된 실행계획이 추진되어야 한다.

In the former aviation law, only the Ministry of Land, Infrastructure and Transport has to provide air traffic services, In the case of providing aviation transportation service from civilian, such as aviation special education institution, private airfield installer, it was possible to carry out only by receiving a private contract from the government. But at the time of private consignment, the fact that the government has to bear the cost through the contract act. It is pointed out that it is a factor that hinders efficiency in the operation sector. Accordingly, in Article 85 of the Aviation Safety Act, which was enforced in March 2017, legal grounds were established to provide air traffic services excluding the Ministry of Land, Infrastructure and Transport. At the same time, we have introduced the air traffic services operating certification system, which enables the air traffic services to meet the requirements set by the Ministry of Land, Infrastructure and Transport in order to secure the safety of air traffic. In this study, we examine the major issues and problems of the small private control tower operated by the private institute in Korea. The effect of introduction of the air traffic services operating certification system which can introduce all the institutions which do not belong to the control agency in the former aviation law into the institutional system and the operation plan were examined.

In this paper, we suggest a system architecture for korean air traffic control system through investigating a korean ARTS (Automated radar terminal system) and ACC (Area control center) system. We focus on designing a network architecture for supporting both an approaching control and an area control. This paper will be a base for developing korean air traffic control system by ourselves.

Recently increase in the number of aircraft caused the air traffic congestion and flight delays. If timely action to reform the air traffic system is not taken, these may result in added economic impact. As a result, the air traffic management should be changed in an innovative manner to modernize the existing air traffic control environment. This paper reviews the trends of airspace reforms such as integration of terminal control areas and flexible use of airspace introduced by foreign countries and compares their merits and demerits in order to provide a judgement to adopt the concept in domestic airspace in the future.

In this study, we propose trajectory-based arrival management using CDO (Continuos Descent Operations). The operational procedures with TBO (Trajectory-Based Operations) concept were established to allow aircraft and ground system to share the trajectories with each other in real time. The proposed operational concept was validated in the air traffic control simulation environment, which consists of controller working position, pseudo pilot system, air traffic generation system, and controllers' decision support system for arrival management using CDO. Simulation results compared with actual flight data indicate that proposed concept could improve the efficiency of traffic flow management in terms of total descending time and fuel consumption. And it was confirmed that if there is a system that can share and utilize the synchronized trajectory, it can be helpful to control arrival aircraft and apply CDO concept.

The purpose of study is to investigate the current user interface level of air traffic control system with the usability analysis and satisfaction survey questionnaire on user satisfaction. Think aloud protocol is used to identify not only task analysis, but also the level of user-friendliness of the FIMS and ASDE system, and the user interface questionnaires was conducted by QUIS. We collected data from 6 controllers for Think aloud protocol and 15 controllers for QUIS in Incheon airport. The results showed that the system was the valuable tool for ensuring human performance with the support of memory and the facilitation of decision-making tasks. It helps air traffic controllers perform better and minimize errors in a congested time. The human-computer interface system design, however, was not applied, which led to the increase of workload. Air traffic controller participation in software development provided excellent examples for applications in terms of software in FIMS. Based on these results, the study provided that the usability of system interface was necessary to take into account human factors. The development and design of system was discussed in User Interface environment.

본 논문에서는 자율비행(Autonomous Flight)의 연구동향 및 향후 발전방향에 대하여 기술하였다. 자율비행은 항공기의 예기치 않은 임의상황 발생에 대해서도 항공기가 스스로 인지하고, 판단 한 후 대처하는 것을 의미한다. 현재의 자율비행기술은 무인기를 위주로 개발되고 있으나, 차세대 항공교통관제 시스템 도입과 무인기의 활용성 증대 요구에 따라 자율비행기능이 항공교통관제시스템과 결합되어야 한다. 그러므로 현 항공교통관제 시스템의 주요 개요와 향후 변경될 차세대 항공교통관제 시스템의 주요 사항들을 살펴보았고, 자율비행기술 개발 현황을 기술하였으며 향후 발전방향을 전망하였다.
