What is the consequence of a runway incursion categorized as C or D by the FAA?

When a runway incursion is categorized as C or D by the FAA, it indicates a situation where there is a potential safety concern for aircraft operations. Category C incursions involve situations that create a significant risk of collision or operational disruption, while Category D incursions might not have resulted in an immediate safety threat, but still signify a serious concern that could potentially affect the aircraft's safety or operations.

These categorizations serve to highlight the varying degrees of urgency and threat, ultimately underlining that any incursion classified in these categories warrants attention due to the possible implications for aircraft safety. Thus, understanding the nuances of these categories is crucial for maintaining operational safety at airports.
