How many tail rotor blades does the TH-73A have?

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

Answer: (B)

The TH-73A helicopter is equipped with two tail rotor blades. This design choice provides a balance between performance and stability, ensuring effective control of the aircraft during flight. The dual-blade configuration helps optimize power efficiency while also contributing to the overall weight management of the helicopter. Additionally, having two blades allows for smoother operation and reduced vibration compared to a single-blade system, enhancing the flight experience for both pilots and passengers. This is important for training purposes, as stability and control are critical aspects of piloting an aircraft.
