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.

The purpose of this research was to identify expertise in ait traffic control by using cognitive skill analysis for novices and experts in routine and non-routine situations. The result of study was to understand expertise in air traffic control tasks in terms of what cognitive processes are responsible for the expert's high performance levels. The problem solving task was difficult for novices, but performed relatively automatically by experts in a routine situation. The difficulty could indicate the presence of controlled processing. Rather than rules and strategies, novices focused more on environmental factors, which merely increase cognitive load. In a non-routine situation, novices showed that they did not categorize the information consistently and alternative resources were not available for them. Experts, however, performed automatically a task by arranging and organizing information related to problem solving components in contexts without regard to a routine and non-routine situation. Especially experts developed a stable representation and directed alternative resources for air traffic flow and efficiency. Based on the results, cognitive processes of experts could be useful to understand expert performance and analyze the learning process, which imply the necessity of developing expertise systematically.

It is necessary to reduce aviation GHG(CO2) emission to ensure aviation sustainable development. Operational improvements may not contribute significantly to carbon reduction but it can sustatially reduce emission in a short term. ICAO has developed GANP and ASBU to optimize operations and countries are making efforts to expand infrastructure and develop technology. The legal barriers to operational improvement are based on the notion of state sovereignty under the Chicago Convention which allows countries to control inefficiencies based on borders or limit or prohibit the passage of aircraft. Chicago Convention does not grant unlimited freedom of air sovereignty and if the concept of state sovereignty is interpreted according to the times it is possible to achieve smooth operational improvement.

The goal for the CD&R system is to predict that a conflict is going to occur in the future, communicate the detected conflict to a human operator, and, in some cases, assist in the resolution of the conflict situation. To provide insight into different methods of conflict detection and resolution, a literature review of previous research models and current developmental and operational systems was performed. This paper focuses only on the specific attributes of each model, not on the depth to which a model has been analyzed, validated, or accepted. Thus, care should be taken to remember that a model that seems to be simple according to our categorization scheme may be significantly more viable than an apparently sophisticated model.

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.

Control and development systems such as air traffic control systems, road traffic systems, and Korea Hydro &Nuclear Power are the infrastructure facilities of the country, and if the malicious hacking attacks proceed, the damage is beyond imagination. In fact, Korea Hydro & Nuclear Power has been subjected to a hacking attack, causing internal information to leak and causing social problems. In this study, we analyze the environment of the development control system and analyze the status of the convergence security research, which is a recent issue, and propose a strategy system for stabilizing various power generation control systems and propose countermeasures. We propose a method to normalize and integrate data types from various physical security systems (facilities), IT security systems, access control systems, to control the whole system through convergence authentication, and to detect risks through fusion control.

The primary objective of this paper is to introduce the application of Human-Machine Interface (HMI) and Augmented Reality (AR) technologies in flight operations. These include: self-check-in, baggage handling, airport security and surveillance, airport operations monitoring, In-Flight Entertainment and Connectivity (IFEC), cockpit design, and cabin crew support. This paper investigates the application status and development trends of HMI and AR technologies for airports and aircraft. These technologies can provide more efficient in-flight passenger service and experience by using AR devices. This paper also discusses the developments such as; the Integrated Control Application (ICA) for the IFEC interface, AR flight simulation training program using the fixed-based simulator, and the AR aircraft cabin interior concept test program. These applications present how HMI and AR techniques can be utilized in actual flight operations. The developed programs in this paper can be applied to their purpose within aircraft interiors and services to enhance efficiency, comfort, and experience.

A UAV is defined as a powered, aerial vehicle that does not carry a human operator, and can fly autonomously or be piloted remotely. UAV operations have increased dramatically during the past several years in both the public and private sectors. The utilization of UAV and the activities of diverse widening, now the challenge was how to operate and integrate UAV safely in the NAS. The purpose of this study is to look around the trend for operability of Smart UAV in the NAS and to provide its implications and the future direction of integrated operating airspace focusing on U.S. where R&D and demand of UAV are the most in the world.

항공기 운항과 관련한 환경의 변화는 다른 분야의 환경 변화보다 그속도가 빠르고 변화의 폭이 크다고 할 수 있다. 약 1세기 동안에 항공기 개발기술은 실로 놀라운변화를 거듭해 왔으며 전자시스템의 도입으로 수 십년 전에는 상상조차 할 수 없었던 일들이 현실로 나타나게 되었다. 본 논문은 이러한 환경변화 가운데 비행안전이라는 목표를 실현하기 위해 우선적으로 항공기 운항과 관련한 환경변화 요인들에 내포되어 있는 문제점들을 분석하고자 하였으며 장비개발 및 Human Factor, 항공교통 관제 및 항공기 운항 그리고 조종사 관리 및 조종 환경으로 분야를 나누어 요인 분석을 함으로써 현재와 미래를 통해 예상되는 문제점들을 도출하였다. 또한 항공기 사고사례를 분석하여 공통되는 요인을 도출, 이를 문제점으로 제시하였다. 이러한 문제점들에 대한 대책에 관한 연구는 항공기 운항 분야의 발전과 비행안전을 위해 계속해서 이루어질 것으로 기대한다.
