What is runway incursion and which measures help prevent it?

• A. A weather event causing runway surfaces to be slick; prevention includes apply de-icing chemicals.
• B. An unauthorized presence on the protected runway area; prevention includes ATC coordination, airside driver training and access control, and reliable signage/markings with good lighting.
• C. A minor hazard on taxiways; prevention includes improved signage only.
• D. An aircraft accidentally crossing runways during takeoff; prevention includes closing runways during all weather.

Answer: (B)

Runway incursion is the unauthorized presence of an aircraft, vehicle, or person on the protected runway area, or an aircraft on the ground entering the protected area without proper clearance. Preventing it relies on a layered approach that combines clear procedures with reliable physical and human safeguards. ATC coordination ensures timely and unambiguous clearances before anyone or anything enters the runway, reducing miscommunication and mistaken entries. Training and access control for airside drivers and personnel help ensure that only authorized individuals operate on the movement area and understand how to obtain and respect runway clearances. Clear signage, markings, and good lighting provide unambiguous guidance at intersections and holding points, helping everyone know where to stop, hold, or cross. Put together, these elements create a safety net that minimizes opportunities for incursions. The other options miss the mark because they focus on weather-related conditions, a minor taxiway hazard, or an extreme measure that doesn’t address the core issue of unauthorized runway access or the practical, day-to-day controls that prevent incursions.
