Which description best matches Category B runway incursion?

• A. An incident that meets the definition of a runway incursion with no immediate safety consequences.
• B. A serious incident in which a collision was narrowly avoided.
• C. An incident in which separation decreases and a significant potential for collision exists, which may result in a time-critical corrective and evasive response to avoid a collision.
• D. An incident characterized by ample time or distance to avoid collision.

Answer: (C)

Runway incursion severity is about how dangerous an incursion was. Category B describes an incursion where separation is decreasing and there is a significant potential for collision, which would require time-critical corrective and evasive action to avoid a collision. This captures the essence of a situation that isn’t a near-miss or collision, but is serious enough to demand immediate action to prevent one. It sits between the most severe cases (where a collision is narrowly avoided or occurs) and the least severe cases (where there’s ample time or distance and little to no collision risk). So the description that emphasizes decreasing separation and a substantial collision hazard requiring urgent action is the best fit for Category B.
