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.

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.

This paper specifies several considerations about assessing safety-critical software in the aerospace domain. In order to evaluate safety critical software in the aerospace industry, it is required to identify an information of evaluation criteria of software under evaluation. The information is specified in the standard, but determination of evaluation criteria cannot be decided by itself and depends on the results of safety assessment of a system and system design. Thus, this paper explains required information of system development standard and safety assessment standard to determine software evaluation criteria. It surveys existing methodologies about evaluating software, and suggests method which is adapted to evaluation of an advanced surface movement guidance and control system (A-SMGCS) software.

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.

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.

This paper proposes a case study of applying to DO-278A, which is a software development standard of ground aviation equipment in communication, navigation, surveillance/air traffic management (CNS/ATM) domain, in order to develop software of Advanced surface movement, guidance and control system (A-SMGCS). It explains considerations to application of DO-278A standard, discusses how to tailor processes or requirements specified in DO-278A in detail, and explain tailored results. And it also summary problems or issues occurred during application of DO-278A, which can be appeared when DO-278A is applied to for the first time by any development part. These are required considerations in order to reduce trial and error. To the conclusion, it explains lessons learned from application of DO-278A and suggest how to solve these problems or issues.

DO-278A는 소프트웨어 인증 절차를 제공할 목적으로 만들어진 것은 아니지만, 소프트웨어 개발 절차를 설명하는 것으로 지상용 항공장비의 소프트웨어를 만드는데 적절한 역할을 수행할 수 있다. 대체적으로, 수명주기증거품(life cycle evidence)을 통해 프로세스가 정확하고 적합하게 이행되었다는 것을 증명할 수 있다면 소프트웨어는 적합성을 확인을 받을 수 있다. 본 논문에서는 국토부 R&D로 개발되고 있는 항공기 지상이동유도 및 통제시스템(Advanced-Surface Movement Guidance & Control System, A-SMGCS)의 소프트웨어 개발 및 검증에 DO-278A 절차를 적용한 방안을 제시하고자 한다.
