When must facility frequencies be monitored?

• A. Only when the position is staffed
• B. Only when the frequencies are in use
• C. During periods of peak traffic
• D. Continuously during hours of operation

Answer: (D)

Continuous monitoring during hours of operation is essential because communication with aircraft, ground vehicles, and adjacent facilities must be possible at any moment. Demands for information, clearances, or urgent/ distress transmissions can arise at any time, and delaying response can lead to safety risks such as miscommunication, sequencing errors, or runway conflicts. By keeping the frequency under constant watch while the facility is open, you ensure you can receive and act on transmissions immediately, maintain situational awareness, and coordinate movements safely. Limiting monitoring to staffed times, only when in use, or only during peak traffic creates gaps where critical messages could be missed, compromising safety.
