Which position transmits IFR departure clearances?

• A. Ground control
• B. Tower
• C. Clearance delivery
• D. Approach control

Answer: (C)

Clearance delivery is the position that transmits IFR departure clearances. Before taxiing, an IFR flight receives the initial route, altitude, transponder code, and any other required instructions from Clearance Delivery. This clearance defines what the flight will do as it leaves the airport and enters controlled airspace. After receiving it, the pilot reads it back and then proceeds with taxiing under Ground Control, and later departs under Tower control for takeoff. Once airborne, Approach Control takes over for sequencing and separation in the terminal and en route phases. The Tower’s role is to manage local runway operations and issue takeoff clearance, not the initial IFR clearance. Ground Control handles surface movements, not the IFR clearance itself. Hence, Clearance Delivery is the correct position.
