What is the operating frequency of the TH-73A's AC system?

• A. 50Hz
• B. 60Hz
• C. 400Hz
• D. 800Hz

Answer: (C)

The operating frequency of the TH-73A's AC system is 400Hz. This frequency is standard for many aviation systems because higher frequencies allow for lighter weight components in electrical systems, which is critical in aircraft design where reducing weight can improve performance and fuel efficiency. The use of 400Hz AC power allows equipment to function efficiently while ensuring stable operation of sensitive avionics and electronic systems. Other frequencies like 50Hz and 60Hz are commonly found in commercial power systems, but they are not suitable for the specialized needs of aviation applications where compactness and efficiency are paramount. The choice of 400Hz ensures that the system meets the rigorous demands of flight operations, making it the appropriate operating frequency for the TH-73A's AC system.
