Which call sign is assigned for Terminal Departure?

The call sign assigned for Terminal Departure is "DEPARTURE." This designation is utilized by air traffic control to manage and coordinate the movements of aircraft as they depart from an airport. Once an aircraft has taken off and is climbing out, it transitions from the control of the tower (often referred to by the tower’s specific name or call sign) to the Departure Control unit, which manages the airspace in the vicinity of the airport and ensures a safe and efficient flow of departing flights into the en-route airspace.

The other call signs serve different functions in the air traffic control sequence. For example, the term "ARRIVAL" refers to the service provided to incoming flights and their management as they approach the airport for landing. "TERMINAL" is a general term that does not represent a specific function within air traffic control operations. "CLEARANCE DELIVERY" is the service that assists pilots with obtaining their flight clearances and initial information before departure but is not involved in the active management of takeoff and initial climb-out phases of flight. Recognizing the specific roles of these various call signs is critical for understanding air traffic communications and operations at airports.
