Which option is not a listed method to improve in-flight stability?

• A. Hover flight
• B. Nose down attitude
• C. Redistribute weight of sling load
• D. Install a drag chute

Answer: (A)

Improving in-flight stability with a sling-load comes from actively damping the load’s motion and tuning the system’s geometry. A nose-down attitude helps keep the load line more stable, reducing the pendulum effect that can cause sway. Redistributing the weight of the sling load shifts the combined center of gravity to a position that lowers swing and makes attitude changes less dramatic. Installing a drag chute adds aerodynamic drag that damps oscillations of the suspended load, increasing stability in variable air conditions. Hovering, by itself, doesn’t actively damp or control the load’s motion; it’s just holding position and doesn’t address the dynamic stability of the sling load. Therefore, hovering is not a listed method to improve in-flight stability.
