Position information need NOT be given when aircraft is identified by which method?

When an aircraft is identified using position correlation, position information does not need to be provided because this method relies on a match between the radar data and the aircraft's reported position. In position correlation, the radar controller is able to establish and confirm the aircraft's identity based on a previously known or calculated position, thus eliminating the need to restate that position during identification.

Position correlation typically relies on the continuous, accurate tracking of an aircraft's movements and relies on the assumption that the aircraft has communicated its position correctly prior to identification. This streamlines the process of identification by allowing controllers to work with that established data, improving efficiency in managing air traffic.

In contrast, identification methods like beacon methods or responding to identification queries require position information to confirm the aircraft's identity. Communicating via emergency frequency involves different protocols, where understanding the aircraft's current position often is essential for the controller's situational awareness and to provide timely assistance.
