The wind direction for Low Hover Single Engine maneuvers must be within how many degrees of the nose?

• A. 60 degrees
• B. 30 degrees
• C. 15 degrees
• D. 45 degrees

Answer: (D)

In a low hover with one engine inoperative, wind direction relative to the nose directly affects how controllable the helicopter is. Keeping the wind within 45 degrees of the nose ensures the pilot has enough directional stability and control authority to hold a precise hover with limited thrust and reduced anti-torque capability. If the wind comes from more than 45 degrees off the nose, the crosswind component becomes harder to counter with the available power and rotor thrust, leading to greater lateral drift, yaw tendencies, and a less controllable hover. A wind limit of 45 degrees provides a practical balance between safety and maneuverability, avoiding the excessive difficulty of larger crosswinds while not being so restrictive that normal training scenarios become impractical.
