DO-178C-based parameter data item airworthiness certification strategy

Abstract

In terms of the airworthiness certification of parameter data item, domestic software manufacturers have some problems, such as unclear certification strategy and insufficient evidence of conformity. Based on the international general software standard DO-178C, combined with the shortcomings of domestic airworthiness certification work and certification practice, the airworthiness objectives and requirements of parameter data item are analyzed, and the suggested airworthiness certification strategy of parameter data item is put forward：1）Embedded parameter data item as a part of the onboard software for airworthiness certification；2）Independent parameter data item as an independent software configuration, according to the proposed planning, development and verification process for development process assurance and airworthiness. Practice shows that this strategy effectively solves the problems existing in the airworthiness work of parameter data item in domestic software manufacturers, and provides high confidence proof of conformity for the airworthiness certification of parameter data item.
