How many AC inverters does the TH-73A have?

• A. One
• B. Two
• C. Three
• D. Four

Answer: (B)

The TH-73A features two AC inverters as part of its electrical system. This design is critical for providing reliable and redundant power supply to essential systems on the aircraft. With two inverters, if one fails, the other can continue to supply power, which enhances the overall safety and operational capability of the helicopter. Having two inverters also allows for better distribution of electrical loads and ensures that the avionics and other critical equipment remain operational even during power fluctuations or maintenance procedures. This redundancy is a key aspect of the aircraft's design, aimed at maximizing reliability in various operational scenarios.
