Software standards for Aerospace industry can be divided into airborne software standards and CNS/ATN(Communications, Navigation, Surveillance/ Air Traffic Management) software standards. DO-178B is software standard for airborne systems and do 278 is software standard for CNS/ATM systems. In order to develop reliable software for aerospace industry, it is necessary to apply these software standards. In this paper, we analysis relationship of assurance guidelines in aerospace industry, system safety process, and software assurance level in DO-178B and DO-278A.
