Completing the handoff is essential before which event?

Completing the handoff is essential before the aircraft enters the receiving controller's airspace to ensure a seamless transition of control from one controller to another. This process is crucial for maintaining safety and coordination in air traffic management. When an aircraft is transferred to a new controller, it is vital that all necessary information, including the aircraft's current position, altitude, and intentions, is communicated effectively.

If the handoff is not completed before the aircraft enters the receiving controller's airspace, there is a risk of communication breakdown, which can lead to misunderstandings about the aircraft's intentions, conflicts with other traffic, or non-compliance with airspace regulations. Completing the handoff ensures that the receiving controller is fully aware of the aircraft's current status and can provide the necessary instructions or approvals as the aircraft moves into their airspace.
