Abstract: Avionics systems in aircraft rely on precise power management to regulate battery charge and control power distribution across electrical systems. This study focuses on designing and constructing a digital ammeter-voltmeter system with a seven-segment display to accurately measure battery charge, discharge, and generator load in helicopters. The system replaces traditional analog meters with an electronic solution that provides real- time numerical readings. By using TC7107 IC, this electronic circuit accurately monitors DC and AC voltage and current levels, ensuring reliable power management. The implementation of this system in two-seater helicopters improves safety and operational efficiency by enabling precise monitoring of power conditions and increase the reliability and accuracy of helicopter operator monitoring. The system is capable of localization, operation, and implementation, and its model simulation has been performed. The results of which are presented in the text of the article, indicating better operational performance and stability of the helicopter's electronic system.
