What is the callsign of the facility that gives route clearances before departure?
Preflight clearance at many large and busy airports is not given by the ground controller who is responsible for coordinating ground movements. During busy times, calls for preflight clearance will block the frequency and make it difficult for ground movement instructions to be provided on time. In such cases, another dedicated ATS unit is provided, tasked with issuing pre-flight clearances to departing aircraft. The main purpose of this unit is to transmit pre-flight information and the call sign is “Delivery”
