What is the typical airspeed at takeoff power for the TH-73A?

• A. 70 KIAS
• B. 75 KIAS
• C. 80 KIAS
• D. 85 KIAS

Answer: (B)

The typical airspeed at takeoff power for the TH-73A is 75 KIAS. This speed is crucial for achieving the necessary aerodynamic lift as the aircraft begins its ascent. It is at this airspeed that the helicopter can establish a safe climb rate, ensuring a stable and controlled takeoff. Following established NATOPS guidelines, maintaining this airspeed helps in minimizing the risk of an uncommanded descent during the critical phase of takeoff, optimizing performance and safety.

The other choices reflect speeds that may not align with the optimal performance metrics for the TH-73A during takeoff, either resulting in compromised climb capability or requiring additional control inputs to maintain stability. Therefore, recognizing 75 KIAS as the standard provides aviators with a clear benchmark for successful takeoff operations.
