Abstract:Under the “OEM-Supplier” aircraft research and development structure, suppliers are responsible for developing airborne software and delivering to the OEM for system integration tests and aircraft tests. The airborne software change could impact on the OEM aircraft research and development, including workload, schedule and cost. This paper firstly identifies the causes of software changes, and classifies them into different categories. The airborne software change impact on the OEM is analyzed including the additional work and cost. Then this paper proposes the OEM airborne software change strategies from the aspects of airborne software quickreturn, software loading and the OEM tests, in order to alleviate the adverse impact of airborne software change on the OEM aircraft research and development.
