In the case of a No.1 inverter failure, will the No.2 inverter power the AC bus bars?

• A. True
• B. False

Answer: (A)

When considering the functionality of inverters in aircraft systems, it's important to understand their role in ensuring reliability and redundancy within the electrical system. In the scenario of a No.1 inverter failure, the No.2 inverter is designed to take over the powering of the AC bus bars. This capability is essential to maintain continuous power supply to critical systems and instruments that rely on AC power.

The primary purpose of having two inverters in such systems is to provide redundancy. If one inverter fails, the other can seamlessly supply power to the AC bus bars without interruption. This feature is crucial for operational safety and reliability, especially in aviation applications where power loss can lead to significant issues.

Therefore, the assertion that the No.2 inverter will power the AC bus bars in the event of a failure of the No.1 inverter is correct, as it reflects the intended design of these systems to enhance safety and operational integrity.
