What is a "runway incursion"?

A runway incursion refers specifically to an unauthorized entry onto a runway. This situation can occur when an aircraft, vehicle, or person enters the runway without proper clearance, which poses significant safety risks to aircraft taking off or landing. The term encompasses any occurrence that involves a breach of the runway's physical boundaries, where the presence of unauthorized entities can lead to potentially dangerous situations.

Understanding the importance of preventing runway incursions is critical, as it directly affects the safety and efficiency of airport operations. Training for individuals operating on the airside often emphasizes the need for vigilance and adherence to protocols that govern access to runway areas. This ensures that all movements in these high-traffic zones are controlled and predictable, significantly reducing the risk of accidents.
