What does the free text abbreviation "T" represent?

The abbreviation "T" in the context of radar and air traffic control often stands for "Traffic." This usage is significant as it refers to the communication of information regarding other aircraft or vehicles in the vicinity, which is crucial for maintaining safety and situational awareness. Understanding this abbreviation helps ensure that personnel can effectively communicate and respond to traffic-related queries or notifications while operating within radar parameters.
