Which direction does the TH-73A's main rotor spin?

• A. Clockwise
• B. Counter-clockwise
• C. Both directions
• D. It varies by flight mode

Answer: (B)

The main rotor of the TH-73A spins counter-clockwise when viewed from above. This is a characteristic design of the helicopter, which influences its handling and flight characteristics. The counter-clockwise rotation helps determine the direction of the helicopter's torque, requiring the tail rotor to counteract this torque to maintain stable flight. Knowing the rotor's direction is crucial for understanding how to operate the helicopter effectively, as well as for predicting how it will respond to pilot inputs. The design consistency in rotor rotation direction across many rotorcraft contributes to standardization in pilot training and operational procedures.
