Comparison of means of compliance for onboard software certification

The purpose of the paper was to discuss means of compliance for onboard software certification. With more than 16 years usage of RTCA DO-178B, the standard has been widely accepted in the industry, and the reality shows that its effect in aviation safety is acceptable. While besides this generic means, from time to time other means have been sought to substitute DO-178B. The paper discussed several means and methods for software certification compliance with the feasibility thereof, and made comparison between them.
