The ability to alter a course of action when new information becomes available is known as ________.

The term that most accurately describes the ability to alter a course of action when new information becomes available is adaptability. Adaptability involves adjusting strategies, actions, or behaviors in response to changes in the environment, circumstances, or information. This is especially important in dynamic fields like technology and unmanned aerial systems, where rapid changes and new data can significantly influence decision-making.

Flexibility is often related but generally refers to the willingness to change or compromise, without necessarily implying how effectively one can adjust based on new information. Responsiveness typically relates to how quickly one reacts to changes, but it does not specifically address the capability to modify plans or approaches based on the context of new data. Scalability, on the other hand, refers to the ability to grow or expand capabilities efficiently, which is not pertinent to the concept of changing actions in response to new information.

Thus, adaptability encompasses the necessary qualities to navigate new information effectively, making it the most suitable answer in this context.
