As ground air traffic control at the airport is one of the most important tasks in air transport, attention to the development of a related simulator has expanded all around the world. For this reason, this research describes the characteristics and advantages of this advanced aerodrome traffic control simulator, developed in South Korea, as well as its linkage with A-SMGCS, which is planned to be developed in the future. One of the characteristics of this simulator is that it is possible to train an air traffic controller independently, especially under various conditions such as in different weathers and normal or abnormal circumstances. Therefore, this aerodrome traffic control simulator, through the comprehensive training under various conditions, will contribute to aviation safety and airport capacity enhancement training.

To perform realistic air traffic control (ATC) simulation in various air traffic situations, an aircraft dynamic model that is accurate and efficient is required. In this research, an improved five degree of freedom (5-DOF) dynamic model with feedback control and guidance law is developed, which utilizes selected performance data and operational specifications from the base of aircraft data (BADA) and estimations using aircraft design techniques to improve the simulation fidelity. In addition, takeoff weight is estimated based on the aircraft type and flight plan to improve simulation accuracy. The dynamic model is validated by comparing the simulation results with recorded flight trajectories. An ATC simulation system using this 5-DOF model can be used for various ATC related research.

An air traffic management (ATM) has been studied in a variety of fields to utilize an air traffic capacity efficiently and solve a congested air traffic situation due to an increment of an air traffic demand. In this paper, an air traffic management, which is related with controlling and determining the sequencing of an aircraft approaching to an airport, in terminal control area is studied. This paper focuses on scheduling algorithms with a given problem for the air traffic management with operational constraints, such as a space separation, an overtaking on the same air-route, and a route merge point (a scheduling point). For a real-time calculation, the presented algorithms focus on dispatching heuristic rules which are able to assign tasks in a fast time period with an adequate performance, which can be demonstrated as a proper and realistic scheduling algorithm. A simulation result is presented to illustrate the validity and applicability of the proposed algorithm. Each scheduling rule is analyzed on the same static and dynamic air traffic flow scenario with the ATM Monte-Carlo simulation.

HLA는 상호 운용성과 재사용성을 목적으로 미국 국방성 산하 기관인 DMSO에서 개발되어진 분산 시스템 프레임워크이다. 이러한 HLA가 민간 부분 적용을 위해 표준이 발표되었고, HLA는 여러 분야의 범용성을 가지기 위해 복잡한 구현 시스템을 가지게 된다. 특히, 객체의 속성변화를 반영하기 위해서는 많은 통신 부하가 발생한다. 이런 단점을 해결하기 위해 제안하였던 객체 관리 모듈을 이용한 항공 교통관제 시뮬레이션을 구현하여 객체 관리 모듈의 성능 및 적용 분야를 평가한다.

With rapid growth in the technologies and demand of Remotely Piloted Aircraft Systems (RPASs), integration of such systems into the existing airspace system is becoming an issue in many countries. RPAS have different flight performances, communication characteristics, separation assurance mechanisms, and human machine interfaces from manned aircraft. To establish rules and regulations for RPAS integration, it is important to understand the impacts of RPASs on the airspace system. A simulation system that integrates manned aircraft, air traffic control, and RPASs is developed in Inha University to investigate these impacts through Human-in-The-Loop (HiTL) simulations. Three conflict resolution scenarios between a manned aircraft and a Remotely Piloted Aircraft (RPA) were constructed and tested. Human factors such as the response times of pilots and controllers were measured and analyzed as well as the risk of each maneuver.

ICAO has recommended the introduction of New CNS/ATM based on GNSS technologies and Data link communication to purpose increasing air traffic demand. The CNS/ATM is composed of communication, Navigation, Surveillance and Air Traffic Management. Cockpit Display Traffic Information(CDTI) that is equipment to share air traffic information to Pilot, Traffic Controller and ground vehicles has been built based on Automatic Dependent Surveillance-Broadcast(ADS-B) information in Surveillance field. This paper is research that what is the effect between pilot and controller through CDTI. Based on ATC communication between Pilot and Controller, We construct simulation environment and did a comparative analysis of it. according to result, We can verify that CDTI makes aircraft Call sign, Position, Altitude information read rate, and notice of air traffic information between Pilot and Controller more improve than ATC environment and Existing Radar System.

This paper describes the effect of advice information for arriving aircraft landing order on the air traffic controller's work efficiency. The air traffic control simulator used in the experiment was modeled on the basis of the aircraft parameters from BADA, gamma-command model and the 4-dimensional trajectory using the Bezier curve. The simulation results show that advice information was helpful for the performance of the work for users who did not have the air traffic control training. On the other hand, in case of users who have experience in air traffic control training, the work efficiency was lowered when the advisory information that does not reflect the user's intention is provided. Therefore, it can be seen that the effect of improving the work efficiency through advice information can be limited depending on the skill level of the air traffic controllers and the complexity of the air traffic situation.

HLA is made for interoperability and reusability as distributed system framework under DMSO. RTI provides the necessary services for message transmission, object management as HLA 's understructure. But its performance can decrease as it becomes larger and more complex because of communication overhead. To solve this problem, RTI and TCP socket are partially used during data exchange and OMM is designed to efficiently manage objects. The efficiency of the proposed method is proved through simulation when it is applied to an air traffic control simulation based on HLA/RTI.
