During HELO OPS, wind speed should be within which range?

• A. 15 to 30 kts
• B. 10 deg
• C. 35 to 45 deg off the port bow
• D. Following Monday

Answer: (A)

Wind over the deck during helicopter operations must be within a safe operating window to ensure stable approach and safe landings. The 15 to 30 knot range provides enough headwind to slow the helicopter relative to the moving deck, aiding precision on final approach and reducing the distance needed to land. It also keeps gusts and deck motion within manageable limits. Wind below this range offers less over-deck airflow, making control and power margins harder during approach. Wind above this range increases deck movement and gust effects, raising the risk of loss of control or rotor/obstacle hazards. The other options don’t describe a wind speed range, so they don’t fit the scenario.
