Due to the lack of navigable airspace caused by worldwide air traffic increases, air traffic control(ATC) services are becoming more complex, which results in the increase of aircraft accidents. To cope with these challenges, major aviation institutes abroad are actively conducting research regarding the human factors affecting controllers but as of late, no such specialized activities have been found in Korea. Due to the dynamic attributes of ATC operations, management of controller's situation awareness(SA) and workload, and knowledge on the impact of abnormal aircraft to controllers are very important. Furthermore, using actual flight data of each country will lead to valuable results, because individually, it has different airspace characteristics and air traffic volumes. This study assumed that air traffic difficulties would affect the controller's SA and workload. To testify the above hypothesis, the abnormal air traffic situations are simulated by using ATC simulator. The findings indicated that the effect of traffic situations containing abnormal aircraft on the controller's SA and workload, it led to demand increase and supply decrease in SA, and increased mental demand, temporal demand, effort and mean workload score in the workload.

The air traffic situation variables were emphasized in this research to review the awareness level of job performance of military air traffic controllers in application of air traffic situation variables such as detection of aircraft identification, type of aircraft, position ,speed, altitude, determination of separation between departing and arriving in-trail aircraft, physical airport conditions, adverse weather conditions, NAVAID outage and ATC facilities' operational status. In this respect, This study was conducted under the auspice of ATC facility operating agencies and devoting air force air traffic controller's participation by answering the questionnaires from nine radar approach control facilities and other air traffic control towers.

본 논문에서는 비행장 관제 시뮬레이터 구현을 위해 필요한 사항을 살펴본다. 비행단계 중 비행장에서의 이착륙 단계는 항공 안전관리 측면에서 매우 중요시 다루어져야 한다. 그 이유는 전 세계 항공기 사고 및 준사고의 60%이상이이 단계에서 발생하는 것으로 조사되기 때문이다. 본 논문에서 항공교통관제 시뮬레이터의 평가 기준인 실습 유형, 장비 형태, 그리고 현실성의 충실도를 통하여 국내 항공교통관제 시뮬레이터의 구현 단계를 평가하고, 현업에 종사하는 항공교통관제사의 설문을 통해 현재 운용 중인 시뮬레이터의 문제점을 검토하여 그 해결방안을 살펴보았다. 또한 이를 바탕으로 개선된 HI-FI 항공교통관제 시뮬레이터의 구현 방향을 제시하고자 하였다.

Air Traffic Control Tower is one of the most important units in Airport operation. It provides services related to safe and efficient traffic flows that control aircraft on the ground maneuvering area and terminal airspace. Also It is responsible for managing of ground operators. The major objective of this study is to evaluates relative efficiency of ATC towers in Domestic airports using data envelopment analysis so that it helps the ATC authority to improve the tower efficiency, to decide the level of benchmarking target and to establish the best alternative. The results of this study are the following; First, as a result of analysis for the potential improvement, it has analysed that the common problems of each ATC tower are to increase its number of flight and to reduce its number of runway followed by airside area, the number of air traffic controller and the number of stand. Second, it has shown that the each tower in RKPC(8), RKPT(5), RKPK(l) and RKSS(l) are used as the reference set. Especially, the tower in RKPC analyzed as a relatively efficient unit is the most main target for the towers in RKTU, RKTH, RKPS and RKTY to do bench marking and to set up the strategy for improving relative efficiency of the tower. Third, tower is actually not able to control the input and output data in this study except the number of controller, so that ATC authority is recommended to improve inefficiency of the towers through handling the number of controller.

The purpose of the Air Traffic Control(ATC) system is to provide a safe, efficient flow of air traffic from origin to destination. Therefor, it is important to reduce the operational errors. Most of errors occurs from controllers. So, we suggest the human machine interface scheme for Air Traffic Control system.

Air Traffic Control is a job that aptitude is strongly needed. According to this, air traffic controllers have to be chosen and arranged by their duty characteristic. With the development of aviation industry, we need more capable air traffic controllers than before. However, it is true that there is no aptitude test for them in Korea. The world wide trend for air traffic control is changing that decision making and high ability with awareness for solving problem. Therefore the aptitude test is certainly required in order to select suitable people having basic abilities for the duty. This research inquires into the aptitude test which is globally taken because of the reason. And with result of that, inspection list is made for development of a tool for aptitude test which is suitable in Korea and additionally there are some special opinions of experts about the list. It is judged that this research will be based for the development of aptitude test in order to select air traffic controller.

Air Traffic Control (ATC) towers play significant role in the functionality of each airport. In spite of having complex dynamic behavior and major role in mitigating post-earthquake problems, less attention has been paid to the seismic performance of these structures. Herein, seismic response of an existing ATC tower with a wall-frame structural system that has been designed and detailed according to a local building code was evaluated through the framework of performance-based seismic design. Results of this study indicated that the linear static and dynamic analyses used for the design of this tower were incapable of providing a safety margin for the required seismic performance levels especially when the tower was subjected to strong ground motions. It was concluded that, for seismic design of ATC towers practice engineers should refer to a more sophisticated seismic design approach (e.g., performance-based seismic design) which accounts for inelastic behavior of structural components in order to comply with the higher seismic performance objectives of ATC towers.

다양한 교통상황에서 현실적인 항공교통관제 시뮬레이션을 수행하기 위해서는 정확성과 효율성이 고려된 항공기 운동 모델이 필수적이다. 본 연구에서는 BADA의 항공기 운용 및 성능 정보를 반영하여 고 충실도의 개선된 5자유도 운동 모델을 개발하였으며, 항공기의 비행 특성이 반영된 제어기 및 유도부를 구성하였다. 이 때, 질점 모델 기반의 BADA 정보를 5자유도 운동 모델에 적용하기 위해 일부 데이터와 관계식만을 선별적으로 차용하였고, 일부 데이터는 항공기 설계 기법을 이용하여 추정하였다. 시뮬레이션 정확도를 향상시키기 위해 항공기 기종 및 비행 계획을 통해 이륙 중량을 추정하였으며, 이를 시뮬레이션에 반영하였다. 개발된 운동 모델은 실제 기록된 비행 궤적 정보와 비교하여 검증 되었다. 본 연구에서 개발된 운동 모델은 관제시뮬레이터에 적용되어 다양한 항공교통 관련 연구에 활용될 수 있다.
