What is the term for any occurrence at an aerodrome involving inappropriate presence on the protected area of a surface designated for landing and takeoff?

• A. Runway incursion
• B. Airfield safety breach
• C. Taxiway incursion
• D. Runway incursion error

Answer: (A)

Runway incursion is the term for any occurrence at an aerodrome involving unauthorized presence on the protected area of a surface designated for landing and takeoff. This covers a person, vehicle, or even another aircraft on the runway while it is being used for arrival or departure, which creates a safety risk of a collision or near-miss.

The other phrases aren’t standard terms for this situation. A safety breach isn’t the established label, a taxiway incursion describes an incursion on a taxiway rather than a runway, and adding “error” isn’t part of the recognized term. Use runway incursion to describe any inappropriate presence on the runway surface during operations. For example, a vehicle entering the runway while a plane is landing is a runway incursion.
