In a landline/interphone handoff, what information does the transferring controller provide that is not included in a physical handoff?

In a landline/interphone handoff, the transferring controller provides specific information related to the aircraft, and one vital aspect that is typically included in this communication is the aircraft's current position. This information is crucial for the receiving controller to ensure a smooth transition of control and maintained situational awareness.

The physical handoff, such as when an aircraft is transferred visually or via radar, generally involves the identification of the aircraft with basic flight data but may not focus as intensively on the precise geographical position of the aircraft at the moment of transfer. During a landline transfer, however, the transferring controller emphasizes the aircraft’s position to ensure the receiving controller is informed about where the aircraft is located relative to their airspace, allowing for more informed and effective separation and traffic management.

By focusing on providing the aircraft's position, the transferring controller ensures that the receiving controller has immediate and accurate context for maintaining safe air traffic control operations.
