What is the necessary action before an aircraft enters airspace delegated to another controller?

Before an aircraft enters airspace that is delegated to another controller, it is essential to coordinate with the receiving controller. This coordination ensures that the transfer of control and communication between different air traffic control sectors happens smoothly and safely, allowing for effective management of the aircraft throughout its flight.

Effective coordination includes sharing pertinent information about the aircraft's current status, intentions, and any issues that may arise, which helps maintain situational awareness and ensures that both controllers are aligned on the handling of the flight. This process is crucial in preventing any potential conflicts or misunderstandings related to the aircraft's movement as it transitions from one airspace jurisdiction to another.

While notifying the pilot of the airspace change, checking weather conditions, and confirming flight plan details may be important actions in some contexts, they do not take precedence over the necessity of inter-controller coordination specifically related to jurisdiction changes. Coordination is a fundamental requirement outlined in standard operating procedures for air traffic control to promote safety and efficiency in the National Airspace System.
