If an aircraft has less than ten minutes before leaving your airspace, what should be done?

When an aircraft is approaching the boundary of your airspace with less than ten minutes remaining, coordination with the next sector is crucial. This process helps ensure a smooth transition of control and continues to uphold safety by maintaining proper separation and communication between sectors.

The need for such coordination arises from the importance of situational awareness and the management of air traffic flow. Air traffic controllers need to inform the next sector about the impending departure of the aircraft, which allows them to prepare for its entry and take any necessary actions for sequencing or altitude adjustments as necessary.

Additionally, this procedure aids in preemptively addressing any potential conflicts that may arise with other aircraft in the adjoining airspace. By ensuring that the next sector is aware and ready to take over, the safety and efficiency of air traffic management is maintained.

The other options do not adequately address the importance of coordination in air traffic management during this critical phase of control transfer.
