Which two factors influence safe wind limits for NOE and sling-load operations?

• A. Gusts/turbulence and crosswinds.
• B. Visibility and pilot skill.
• C. Crosswinds and visibility.
• D. Temperature and altitude.

Answer: (A)

When you’re doing NOE or sling-load work, the wind factors that most directly affect control and safety are gusts or turbulence and crosswinds. Gusts and turbulence produce rapid, unpredictable changes in wind speed and direction, which can suddenly alter rotor lift, attitude, and the load’s behavior close to obstacles or terrain. Crosswinds push the helicopter sideways and can cause the load to swing or drift, making precise hover and load placement far more challenging in tight, low-altitude conditions. Visibility and pilot skill influence how well you manage risk, but they don’t set the wind limits themselves. Temperature and altitude change performance, not the wind’s behavior, so they’re not the primary wind-limit factors.
