What is the purpose of a runway incursion advisory?

The purpose of a runway incursion advisory is fundamentally to prevent unauthorized access to runways. Runway incursions can create hazardous situations where aircraft, vehicles, or personnel inadvertently enter a runway when it is not safe to do so, potentially leading to collisions or near-miss incidents.

By issuing advisories related to runway incursions, air traffic control (ATC) is able to warn pilots and ground personnel of any potential conflicts or risks of unauthorized entry onto the runway. This enhances safety by ensuring that all traffic operations are aware of the current status of the runway and any potential hazards.

While aspects like indicating holds, assisting in emergency landings, or directing traffic on taxiways are essential components of air traffic management, they do not specifically address the critical issue of preventing unauthorized runway access, which is central to the function of a runway incursion advisory.
