What characterizes a Category B Incursion?

A Category B Incursion is characterized by significant potential for a collision that requires a time-critical response from pilots or air traffic controllers. This classification indicates that while an actual collision may not have occurred, the situation posed a serious threat that required immediate attention to prevent a dangerous outcome.

In the context of this classification, it reflects an imminent risk where the actions of flight crews or ground personnel are crucial to avoiding adverse events. The essence of a Category B Incursion lies in the urgency and the potential consequences of the situation, underscoring the need for vigilance and prompt corrective action during operations.

The options highlighting insufficient time to avoid a collision or ample time do not accurately represent the immediacy or severity associated with a Category B Incursion. Similarly, while immediate safety consequences are present in this context, the defining feature is the significant potential for collision demanding a swift response.
