Software development and management methods for complex avionics systems for civil aircraft

The software development process encounters several challenges due to the increasingly functional, complex, expensive, and condensed development cycles of civil aircraft avionics systems, including inaccurate requirements, overly coupled architecture design, and difficult tracing of process outputs. Based on the research of advanced technologies and methods, such as digital development, process development, continuous integration,cloud development environments, a solution is proposed for software development issues in complex civil aircraft avionics systems. In this paper, it is demonstrated how the solution for civil aviation software development is used in the process of developing avionics systems software. The viability of the complex avionics system software development and management method for civil aircraft proposed are also demonstrated. To increase the effectiveness and caliber of software development, the method has been used in the development of the C919 civil aircraft display system.
