Which statement describes the use of CTAF in airport operations?

• A. To monitor airport traffic when a control tower is not in operation.
• B. To receive ATC clearance.
• C. To contact ground operations for baggage.
• D. To communicate with weather services only.

Answer: (A)

Common Traffic Advisory Frequency is the radio channel pilots use to broadcast their position and intentions when there is no active air traffic controller in the tower. This lets pilots self-coordinate with other traffic on and around the airport, helping maintain situational awareness and avoid collisions on non-towered fields or when the tower is closed. It isn’t used to receive ATC clearances—that requires contacting the appropriate ATC facility on a tower or clearance-delivery frequency. It also isn’t for contacting ground operations or obtaining baggage services, nor for weather updates (those come from ATIS, AWOS, or METAR/TAF broadcasts). When a control tower is in operation, pilots use the tower frequency instead of CTAF.
