AI Technical Summary

Problems solved by technology

[0005] The purely digital aircraft centralized maintenance system simulator lacks intuitive observation effects and operating experience, and cannot reliably simulate the electrical characteristics of the aircraft centralized maintenance system, resulting in inconsistencies between the experimental environment and the real aircraft working environment

[0006] Simulation devices that rely solely on real avionics components are expensive and have complex interfaces. Once the system structure is fixed, it is difficult to change the configuration according to multi-level simulation requirements, and the applicability is not strong
