Abstract: The control system serves as a critical component of large complex aircraft, playing a vital role in the aircraft′s flight attitude and motion control. The maintenance tasks for such control systems are not only complex but also require a high level of expertise, with the precise monitoring and maintenance of numerous technical parameters being necessary to ensure system reliability and safety. In light of this, the development of an intelligent information management system has become a key strategy to enhance the performance of the control system. This system features real-time monitoring and early warning capabilities, intelligent fault diagnosis, and effective maintenance solutions, while also supporting continuous system optimization and technological upgrades. Through these measures, the intelligent information management system effectively guarantees the smooth operation of large complex aircraft and the successful completion of various flight missions.
