Who may be authorized to operate up to the edge of an active runway when necessary?

The authorization for operating up to the edge of an active runway is primarily designated for vehicle operators, equipment, and personnel who maintain direct communications with the control tower. This protocol is essential for ensuring safety in an environment where aircraft movements are occurring. When a party is in direct communication with the control tower, they can receive real-time instructions and situational updates, which is critical in avoiding potential conflicts with aircraft on approach or departure.

Through this communication, authorized personnel can coordinate their movements effectively, ensuring they do not inadvertently disrupt air traffic operations. Such operational procedures help maintain the safety and efficiency of airport operations, allowing ground activities to proceed while safeguarding the overall integrity of the air traffic control system.

In contrast, other groups like airport managers, emergency responders, or maintenance staff may not have the same level of communication capability or operational authorization to be on or near active runways without prior coordination with the control tower. Their functions are typically managed in a manner that does not intersect directly with active flight paths, thereby creating a structured and safe airfield environment.
