Recently, it is actively under study for the implementation of advance surface movement ground control systems (A-SMGCS) level IV in Korea. To ensure the safety of the A-SMGCS system needs the safety assessment, and Eurocontrol is encouraged to perform the functional hazard assessment, preliminary system safety assessment, and system safety assessment to the safety assessment of A-SMGCS. In this paper, we identify the hazard of A-SMGCS through a functional hazard assessment. Therefore, we will identify 29 types of hazard for the A-SMGCS level IV and serve as important data to evaluate the severity of each hazard.

The A-SMGCS is a modular system defined in the ICAO manual on advanced surface movement guidance and control systems. Such systems aim to maintain the declared surface movement rate under all weather conditions while maintaining the required level of safety. In this paper, we find out the details and 14 modules'specific features that developing Level IV A-SMGCS in Korea. Also we figure out relation domestic regulations as SMGCS manual & visual aids manual in Korea and research foreign cases such as defined ICAO 9830 manual, EUROCONTROL's project 'EMMA2' document, and FAA advisory circular-150 manual. It will be used as analysis data that can be applied to the undefined A-SMGCS in Korea technical regulation.

In this paper, we states the verification and validation methodology for the modular system of A-SMGCS which defined in the ICAO Manual on Advanced Surface Movement Guidance and Control Systems. Such systems aim to maintain the declared surface movement rate under all weather conditions while maintaining the required level of safety. With the complete concept of an A-SMGCS, air traffic controllers, vehicle drivers, flight crews, and are assisted with surface operations in terms of surveillance, control, routing/planning and guidance tasks. A-SMGCS verification and validation for the development of Real Time Simulation, shadow mode trials, operational trials are conducted through three methods. In this study, the characteristics and the need for such a verification method was examined.

A-SMGCS 시스템은 HMI 단말 노드, 외부 시스템 연계 노드, 운영 데이터베이스 노드, 서버 노드 등 여러 노드로 구성되어져 있으며 이 노드들이 협업하여 운영자에게 원활한 서비스를 제공하기 위해서는 최소한의 공유 데이터가 서로 동기화되고 변경 발생 시 해당 노드에 자동으로 통지될 수 있어야 한다. 본 연구에서는A-SMGCS 시스템 운영에 필요한 최소한의 공유 데이터 동기화 및 변경 통지 기능 제공을 위해 협업 미들웨어인 ZooKeeper를 활용하고자 한다. 본 연구를 통해 클러스터를 구성하는 복수개의 ZooKeeper에 공유 데이터를 계층적으로 저장하고 특정 데이터에 변경이 발생할 시 자동으로 A-SMGCS 시스템 노드들에 통지가 됨을 확인하였다. 이러한 기능은 A-SMGCS 시스템뿐만 아니라 시스템 노드 간 신뢰성 있는 공유 데이터 실시간 동기가 필요한 다양한 시스템에도 쉽게 적용이 가능하다.

This study is safety assessment standard for advanced surface movement guidance control system (A-SMGCS) and case study of the past research project. A-SMGCS providing routing, guidance and surveillance for the control of aircraft and vehicles in order to maintain the declared surface movement rate under all weather conditions within the aerodrome visibility operational level while maintaining the required level of safety. Recently, in korea and europe are developing A-SMGCS system for the safety control of the airport movement area. In safety oriented industry such as aviation that it is necessary to verify and ensure for operating system. In this case study, analysis of safety assessment standard for verified A-SMGCS target level of safety (TLS) and previous developed A-SMGCS research project.

A-SMGCS는 진화하는 개념으로 현재 공개된 기준이나 권고사항의 일반요건들이 모두 유효하지는 않지만, 기술요건을 도출하기 위한 방법론으로 ICAO, EUROCAE, 유럽항행안전기구 문서에서 정확한 운용, 기능, 성능상의 요건을 추출하여 이러한 요건을 아키텍처 구조에 반영하여야 한다. 타 프로젝트의 A-SMGCS 지상시스템 기술요구 문서의 성능요구사항 사례 연구를 통해 A-SMGCS 개발 시에 고려할 성능요구사항을 고찰하였다.

Advanced surface movement guidance and control system (A-SMGCS) is a system providing routing, guidance and surveillance for the control of aircraft and vehicles in order to maintain the predetermined surface movement rate under all weather conditions while maintaining the required level of safety. In the present study, system engineering was introduced to develop the compliance procedure for the A-SMGCS. At first, requirements for the level IV A-SMGCS were defined and analyzed from the concept of operations (CONOPS). Then, system architecture and specifications were constructed through the functional analysis and allocation. After that, work breakdown structure (WBS) and related integrated master schedule (IMS) were established. Lastly, compliance checklist (CCL) and test and evaluation master plan (TEMP) were developed to verify and validate the system.

Safety assessment is necessary to develop safety related CNS/ATM system. It includes functional hazard assessment (FHA), effects eliciting system safety requirement that mitigates system's hazardous event. This paper performs a case study for functional hazard assessment of A-SMGCS. To do this, related A-SMGCS studies from Eurocontrol and EMMA are surveyed, and assessment schemes of functional hazard from Eurocontrol and EMMA are combined. Not only FHA scope but also several assumptions for FHA are defined for Incheon airport. 29 hazards are identified and their severities are assessed. And exposures and safety objectives from hazards are analyzed using event tree analysis method. Differences between result of this study and result of EMMA are analysed, and assessment results in this study are also reviewed.
