Category C runway incursion is described as:

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

Answer: (A)

Runway incursion severity categories gauge how close a situation came to a collision and how urgent the corrective action needs to be. In this scheme, the category described as “ample time to avoid” means the incursion was detected with enough time and space for the involved aircraft or vehicle to take action and prevent a collision. There is no immediate safety threat, and responders have a comfortable margin to react. This is why the description aligns with the option stating ample time to avoid. The other descriptions imply greater immediacy or risk (narrowly avoided serious incident or significant potential for collision) or no immediate consequences, which do not fit this category.
