Abstract

Maintainability in engineering terms means ease of maintenance / management of the product. Aircraft automatic test equipment (ATE) is heavily influenced by the design changes of the unit under test(UUT) since the test procedure is developed according to the function / performance characteristics of the UUT. Moreover, if the integrated ATE is an environment that checks more than one UUT, it is not easy to maintain the ATE for the UUT design changes. Developers should be able to flexibly cope with the change of development staff by selecting an easy and clear development method to improve the maintainability of ATE. It is also necessary to limit the area affected by the UUT design change to a specific range to minimize the area to be modified. In this paper, we propose ATE development method which focuses on maintenance improvement based on the aircraft ATE development process.

공학 용어로 유지보수성(maintainability)은 제품의 유지/관리에 대한 용이성을 의미한다. 비행체 자동점검장비(ATE)는 점검대상장비(UUT)의 기능/성능 특성에 따라 점검절차가 개발되기 때문에 UUT의 설계 변경에 많은 영향을 받는다. 더욱이 통합 ATE가 다수의 UUT를 점검하는 환경이라면 UUT 설계 변경에 대한 ATE의 유지보수가 쉽지 않다. 개발자는 ATE의 유지보수성 향상을 위하여 쉽고 명확한 개발 방식을 선정하여 개발 담당자의 변경에 유연하게 대처할 수 있어야 한다. 또한 UUT 설계 변경에 영향을 받는 영역을 특정 범위로 제한하여 수정될 부분을 최소화할 수 있어야 한다. 본 논문에서는 비행체 ATE 개발 과정을 기반으로 유지보수성 향상에 초점을 둔 ATE 개발 방안을 제안한다.
