What best defines a runway incursion?

What best defines a runway incursion?

• A. A weather event affecting a runway surface.
• B. A situation where an unauthorized aircraft, vehicle, or person is on a runway during aircraft operations.
• C. A published procedure for crossing runways.
• D. A temporary runway closure due to construction.

Answer: (B)

Runway incursions are about safety risk from unauthorized presence on the active runway. The best definition captures the situation where an aircraft, vehicle, or person is on the runway during aircraft operations without proper clearance. This creates the potential for collisions or runway incursions during landings and takeoffs, which is why this option is the correct one. The other ideas describe things that are not incidents of unauthorized presence on a runway during operations—weather affecting the runway, a published crossing procedure, or a temporary closure due to construction. These are different concepts and do not define an incursion.
