Which description best fits Category A runway incursion?

• A. Narrowly avoided serious incident
• B. Significant potential for collision
• C. Ample time to avoid
• D. No immediate safety consequences

Answer: (A)

Category A describes a narrowly avoided serious incident. It represents the most serious level of runway incursion, where a collision was imminent but narrowly prevented. That’s why the description “narrowly avoided serious incident” is the best fit. The other choices describe less severe situations: a significant potential for collision without a near-miss isn’t captured as strongly as a near-miss, while ample time to react or no immediate safety consequences indicate no actual risk of collision.
