How do ATC controllers coordinate with other agencies?

ATC controllers coordinate with other agencies primarily by communicating with entities such as fire services and medical teams. This communication is critical in ensuring the safety and efficiency of airport operations, especially in emergency situations. When an incident occurs, such as an aircraft malfunction or medical emergency, air traffic controllers must quickly relay information and respond effectively to external agencies that provide necessary support. This collaboration helps to expedite emergency response times and maintain situational awareness for both pilots and emergency service providers.

While other options may involve elements of airport operations, they do not focus directly on the essential coordination role of ATC controllers with external agencies during emergencies. For instance, conducting training sessions and managing flight schedules are important but relate more to internal operational readiness rather than direct communication with external emergency services. Similarly, controlling the airport gates pertains more to ground operations rather than the critical coordination needed with external agencies during emergencies.
