To communicate to an airport without tower control, you should do what?

• A. Communicate/Switch to common communication frequency
• B. Transmit on your assigned frequency
• C. Call the tower on emergency frequency
• D. Contact the weather briefing line

Answer: (A)

When there’s no active tower, there’s no one to actively sequence traffic or give you clearance. Pilots use the published common advisory frequency (CTAF/UNICOM) for that field so everyone can hear each other and coordinate entry, approaches, takeoffs, and pattern work. Switching to that common frequency and announcing your position and intentions creates a shared picture of traffic and prevents conflicts. Using your assigned frequency wouldn’t ensure coordination with other pilots at that uncontrolled airport, the emergency frequency is for distress calls only, and the weather briefing line is for preflight weather information, not ongoing air-to-air communication.
