A brief analysis of civil aircraft airborne software deactivated code
LIAO Kai;JU Hui;Shanghai Aircraft Design and Research Institute;
The safety requirements of civil aircraft determine that airborne software needs to meet more requirements than ordinary software. If the deactivated code is accidentally activated, it will result in different levels of damage to the safety of the aircraft. How to avoid or mitigate the accidental activation of deactivated code by process assurance method is a common concern of the airborne software development unit and airworthiness certification authority. According to the special attributes of the airborne software deactivated code, this paper analyzes the requirements related to the deactivated code in the industry standards from the process of software planning, design and verification. Meanwhile, from the perspective of airworthiness certification authority, it interprets the authority's concerns about the deactivated code in the aspect of airworthiness compliance verification.
