How often do ATC personnel monitor radio and interphone frequencies?

• A. Always
• B. Hourly
• C. Continuously
• D. Only during emergencies

Answer: (C)

Continuous monitoring of radio and interphone frequencies is essential for ATC. Communications from pilots can arrive at any moment—routine instructions, position reports, weather updates, or emergencies—so there must be no gaps in listening during a controller’s shift. Keeping the assigned frequencies under continuous watch allows ATC to respond immediately, issue instructions without delay, and coordinate with adjacent sectors or facilities as needed. This readiness also ensures rapid handling of distress or urgency signals, which is critical for maintaining safety and orderly traffic flow.
