Which of these conditions negatively affects load stability?

A high center of gravity significantly impacts load stability in sling load operations. When the center of gravity is elevated, it increases the likelihood of tipping or swaying during transport. This instability can lead to the load swinging unpredictably, creating a hazardous situation for both the load itself and the aircraft. In contrast, a lower center of gravity contributes to more balanced and stable load behavior, helping to ensure safe transport.

While other conditions, such as low winds and stable weather, typically promote stability, a high center of gravity inherently complicates the dynamics of the load, making it more susceptible to external forces.
