A head wind is defined as wind within how many degrees of the aircraft's land heading?

• A. Wind within 60 degrees left or right of land heading
• B. Wind within 30 degrees left or right of land heading
• C. Wind within 45 degrees left or right of the land heading
• D. Wind perpendicular to land heading

Answer: (C)

Wind direction relative to the landing heading is categorized to help you plan and execute a safe hover/landing for sling loads. A headwind is defined as wind blowing from ahead within 45 degrees of the aircraft’s land heading. That means the wind is coming from in front, in a narrow cone, which increases lift and gives better control during approach and hover by reducing groundspeed and enhancing rotor performance. Winds more off the front than that become crosswinds, which introduce more yaw and drift, while winds from behind are tailwinds and can reduce lift. So, the best answer is the wind coming from ahead within 45 degrees of the landing heading.
