Which category of runway incursions signifies an incident with no immediate safety consequences?

The correct answer indicates that a Category D runway incursion pertains to incidents that are identified as having no immediate safety consequences. This classification is significant because it helps air traffic control and airport personnel understand the severity and potential risks associated with incursions on the runway.

Category D incursions typically involve situations where an unauthorized entry onto the runway or taxiway occurs, but there is no imminent danger or disruption to air traffic operations. This could include scenarios such as an aircraft or vehicle being on the runway but not interfering with other aircraft movements.

Recognizing incidents in this category allows for a focus on preventative measures and training to avoid future incursions, maintaining safety standards without overreacting to lower-risk situations. Understanding the nuances of runway incursions helps ramp agents and other airport personnel respond appropriately to various scenarios and manage safety effectively.
