This paper proposes a prediction model of air traffic controller's take-off clearance under mixed mode runway operations. The proposed model has its purpose on the better prediction of the air traffic controller's clearance on take-offs of departure aircraft by considering various factors. For this purpose, support vector machine classification algorithm is used for the proposed model. The proposed model is applied to real air traffic operations to demonstrate its performances.

본 논문은 국제민간항공기구(ICAO) 국제기준에 부합하기 위하여 항공교통관제사에 대한 피로위험관리시스템(FRMS)의 도입 및 시행을 앞두고 과학 데이터 기반에 근거하여 우리에 적합한 FRMS 구축을 위한 규범적 대안을 제시하고자 한다. 따라서 현행 국내운영기준에 대하여 항공관제기관별 운영을 확인하고, 해외 각국의 항공교통관제 기관별 운영 방식과 기준을 비교·검토하였다. 우리나라의 관제사는 주/야 최대 근무시간 10시간, 최소휴식 8시간, 주 40시간으로 규정하고 있다. 현재 항공교통관제기관의 경우의 주간의 경우는 기준시간과 적합한 근무를 하나, 야간의 경우는 평균적으로 5.9시간을 초과한다. 그리고 주 40시간 경우 평균적 15.7시간의 초과근무를 하고 있다. 이러한 야간 근무시간 조정 방법으로 인원보충에 의한 적절한 야간 근무시간 배분과 더불어 근무교대 방식이 1일 2교대(주/야) 방법이 아닌 개인 schedule에 따른 근무자 투입 방식의 형태를 다양하게 함으로써 이를 해결하여 나갈 수 있을 것을 제안하고자 한다.

This paper tried to analyze the response of air traffic controller(ATC) against abnormal situations using survey based on cognitive strategies suggested by Malakis et al.(2010). The survey designed to empirically analyze the effect of the cognitive strategy factors on organizational effectiveness. The main purpose of this research was as follows: First, it was analyzed both the individual-scale and team-scale factors which constructed the cognitive strategy against abnormal situations. Secondly, how seriously impact the ATC's cognitive strategies on their organizational effectiveness. The organizational effectiveness was divided into such two latent variables as job absorption and job satisfaction. According to the a analysis, it was proven that premeditated act of ATC had a positive significant effect on team-scale cognitive strategies such as teamwork, communication and error management. Moreover, it was found out the team-scale cognitive strategies had also a positive significant effect on job absorption. On the other hands, individual-scale cognitive strategies had no or negative effect on job absorption. Job absorption was proven to have a significant effect on job satisfaction of ATC.

The purpose of this study was to evaluate an effect of the new air traffic control display designed by Ecological Interface Design [EID]. The methodology of EID has not been applied to the development of the air traffic control display so far. To design a new air traffic control display by EID, We implemented Work Domain Analysis about the air traffic control domain and made the Work Domain Model that consisted of the five levels of the Abstraction Hierarchy. We extracted the Information Requirement from the completed Work Domain Model and the extracted information requirements from the model were used to design the new air traffic control display. We evaluated an effect of the new air traffic control display designed by EID. Participants for evaluating consisted of 14 active military air traffic controller of the Republic of Korea Air Force. Experiment was designed two factors within subject. Factors manipulated in the experiment included displays type to compare the existing type with the new ecological interface type and included complexity to compare the effect of the high complex situation with the effect of the low complex situation. Response time about questions with relation to air traffic collision situation, accuracy, and subjective work load were measured. The results reveled that EID type's display has a significant effect on response time, accuracy, and subjective work load and verified that EID could be applied to the air traffic control domain that is more complex and dynamic.

본 논문에서는 동적 공역 형상 관리상의 변경이 발생할 때에 대한 항공 교통 효율성 평가에 사용될 궤적기반 항공 교통량 분석 소프트웨어의 설계 결과를 기술한다. 본 소프트웨어는 비행계획서에 기초한 인천 FIR의 항공 교통에 대한 통계 자료를 산출하고, 비행계획서 상의 항공기 종류, 순항고도, 속도, 이동 경로 등으로부터 도출된 궤적 모델링 자료를 이용하여 항공로 이용율, 관제사 관제량을 분석하도록 설계되었다. 공역 설계 및 항공로 입력 정보와 함께 장기간에 걸친 궤적 모델링 자료를 한꺼번에 입력받아 일괄 처리하는 방식을 적용함에 따라, 본 소프트웨어는 공역 및 항공로 등의 수정 내용에 따른 교통량 변화를 빠르게 예측할 수 있는 장점을 가진다.

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.

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.

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 Controllers (ATC) are also essential to the efficiency of airports and the airline industry. With the increasing volume of traffic, managing flights is a complex and sometimes very stressful job. ATC is using radar and other technology to track planes 'en route' between airports and keep in touch with pilots. Alternatively, ATCs are liaising with the planes on approach. However, ATC's working condition is getting more stressful, as the volume of air traffic increases. Thus this paper tried to research cognitive emotional regulation, job satisfaction, and job involvement and organizational committment of ATCs under the stressful work condition, taking care of safety of a couple of hundreds passengers per plane. Using CERQ survey sheet (Cognitive Emotional Regulation Questionnaire), it was found out that positive thinking and acceptance of self-blame have a significant impact on job satisfaction, work absorption and organizational Loyalty.
