How often must airports verify the operational status of ARFF communications systems?

• A. Every hour
• B. Every 12 hours
• C. Every 24 hours
• D. Every week

Answer: (C)

Airports must verify the operational status of Aircraft Rescue and Fire Fighting (ARFF) communications systems every 24 hours to ensure effective and reliable communication during emergencies. This frequent verification is crucial because the timely dissemination of information and coordination during a fire or rescue operation can significantly impact safety outcomes. Regular checks help in identifying any malfunctions or issues with the communication systems, allowing for prompt repairs or replacements before an incident occurs.

Compared to the other frequencies listed, a 24-hour interval strikes a balance between operational readiness and practical oversight, ensuring that systems are consistently maintained without overburdening personnel or resources. More frequent checks, like every hour or every 12 hours, may not be necessary for typical operations and could divert valuable resources from other critical tasks. Weekly checks would not provide the level of immediacy and responsiveness needed in the dynamic environment of airport operations.
