In air traffic control, what does "clearance delivery" refer to?

"Clearance delivery" refers to the process of providing pilots with their flight plans and departure instructions before they begin their flight. This includes issuing the clearance necessary for the flight to operate safely, which involves giving pilots key information on how to proceed from the departure airport to their intended destination.

The role of clearance delivery is essential in ensuring that all flight details are verified, including the route and expected altitudes, as well as any necessary traffic advisories. Pilots receive this information before they taxi to the runway, allowing them to prepare for takeoff in an organized manner that maintains safety and efficiency within the airspace.

This process is distinct from other aspects of air traffic control, such as issuing instructions for taxiing to the runway or granting takeoff approval, which occur at different stages of the flight process. It is also separate from emergency assistance requests, which are handled under different protocols. By understanding clearance delivery, pilots can ensure that their operations align with air traffic control expectations and comply with regulations.
