What does the "C" in the IFR departure clearance acronym "CRAF" stand for?

In the context of IFR departure clearances, the "C" in the acronym "CRAF" stands for "Cleared to." This element of the clearance is crucial because it indicates that the pilot has received official authorization from Air Traffic Control (ATC) to depart to a specific destination or route. Understanding this terminology is essential for pilots to ensure they follow standard procedures and maintain compliance with ATC instructions.

The term "Cleared to" serves as a precursor to the specific details of the clearance, which generally include the destination airport, the initial routing, and any altitude restrictions. This authorization is a legal command for the pilot to proceed with the planned departure, setting the stage for the flight operation following the established IFR protocols. Knowing this context helps pilots to correctly interpret and respond to their IFR clearances, ensuring safety and efficiency in their flight operations.
