A procedure that initiates verbal coordination for departure release approval is defined as what?

The procedure that initiates verbal coordination for departure release approval is known as Call for Release (CFR). This term is commonly used in air traffic control operations to refer to the communication process that controllers use to confirm and coordinate the release of an aircraft for departure. When a controller makes a Call for Release, they are essentially seeking approval from the appropriate authority, ensuring that all safety and operational protocols are adhered to before the aircraft takes off.

This process is crucial in managing the flow of air traffic, as it helps to prevent conflicts and ensure that departures can occur in an orderly manner. The CFR is also an important part of maintaining situational awareness among controllers and pilots, as it formalizes the communication needed to safely transition an aircraft from the ramp or taxiway to the runway.

Understanding this procedure is essential for effective air traffic management, as it directly impacts not only the departing aircraft but also the overall efficiency of the airspace.
