Due to the complexity of the airborne system,it is difficult to implement exhaustive testing.To assure the system airworthiness,relevant sets of standards have been issued by SAE and RTCA,defining the development process.However,the standards are established in the way of “what” rather than “how”.Consequently,it requires the users to not only understand,but also formulate a localized procedure in order to apply these standards effectively.The airborne electronic system is a typical complex system,thus a localized procedure is needed for establishing the system airworthiness standard.This paper proposes a method to construct customized development process for the airborne electronic systems.The method considers both management requirements and engineering approach to target an integrated,flexible and efficient process.
