What does the transfer of radar ident from one controller to another without transferring communications describe?

The transfer of radar identification from one controller to another without transferring communications is referred to as a Point Out. This process is used in air traffic control when one controller needs to inform another controller of an aircraft's radar identification while keeping the current communications with the first controller.

In this scenario, the first controller provides the second controller with the necessary information about the aircraft's position, intentions, and any other pertinent data, allowing for continued situational awareness and coordination of air traffic without requiring the aircraft to change frequencies or communicate with the second controller immediately. This technique is essential for maintaining safety and efficiency in air traffic management, particularly in busy airspace where multiple controllers are interacting with the same aircraft.

The other options have distinct definitions. For example, Coordination typically involves discussing operational details and ensuring that both controllers are aligned on how to manage traffic but does not involve radar ident transfer in the same manner as a Point Out. Hand-Off specifically refers to the transfer of both radar identification and communications from one controller to another, which is not the case here. Information Transfer is a broader term that might encompass various types of data sharing but does not precisely describe the unique act of transferring radar ident without transferring communications.
