When making a point out via landline/interphone, you must inform the receiving controller of the aircraft's what?

When making a point out via landline or interphone, it is essential to inform the receiving controller of the aircraft's position. This information is crucial because it allows the receiving controller to assess the current location of the aircraft in relation to other traffic and ensure safe coordination between controllers. The position helps to identify whether the aircraft is on a converging course with other aircraft and aids in maintaining effective separation.

Providing the aircraft's position is key for situational awareness and for facilitating a smooth handoff between controllers. It ensures that the receiver has the necessary information to manage their airspace effectively, particularly in busy air traffic environments. While speed, flight path, and altitude are also important factors for a controller to know, the immediate priority when making a point out is to ensure that the receiving controller understands where the aircraft currently is.
