What does a taxiway incursion refer to?

A taxiway incursion refers to the unauthorized entry of an aircraft or vehicle onto a taxiway area that creates a potential hazard for other aircraft. It can involve situations where an aircraft mistakenly enters a taxiway without clearance, thereby compromising the safety of operations on the ground. Such incursions can lead to dangerous situations, especially if another aircraft is taxiing on the same taxiway or preparing for takeoff or landing.

Understanding the significance of a taxiway incursion is critical for maintaining safety at airports, as it helps prevent accidents and ensures proper communication and coordination between air traffic control and ground operations. The term is specific and relates directly to ground movement, distinguishing it from other scenarios involving runways or collisions.
