Monitoring and Diagnostics of the Technical Condition of Built-in Power Sources of Aviation Equipment

Considering that the majority of aviation equipment includes built-in sources of secondary power supply, the article proposes to introduce additional functions of monitoring and diagnostics of switched external equipment into local load control centers of aircraft. Using an external signal source, it is possible to estimate the amplitude-frequency characteristics of the built-in sources of the secondary power supply. Analyzing the amplitude-frequency characteristics you can monitor and diagnose the state of the input circuits of aviation equipment.
