What is the relative wind requirement to manipulate the training switch for the High Hover single engine maneuver?

• A. 5 knots within 60 degrees of the nose
• B. 0 knots within 90 degrees of the nose
• C. 10 knots within 45 degrees of the nose
• D. 15 knots within 30 degrees of the nose

Answer: (C)

In this maneuver, having a modest, predictable relative wind helps you feel and control the helicopter as you manipulate the training switch for engine-out simulation. A relative wind of about 10 knots coming from within 45 degrees of the nose provides enough airflow to stabilize the rotor disc and give you reliable control feel, without introducing strong crosswinds that would make the switch manipulation erratic.

If the wind is too low or zero, you lose that added stability and the switch might not respond consistently to the intended engine-out condition. If the wind is too strong or from a narrower angle (for example, a higher speed in a tight nose cone), gusts and crossflow can push the helicopter and complicate precise control during the setup, making the maneuver harder to execute safely.

So, the 10-knots relative wind within 45 degrees of the nose offers a practical balance: sufficient, stable airflow to perform the training switch manipulation reliably in the High Hover single-engine scenario.
