To ensure adequate spacing for safety of flight, and also track changes in aircraft airspeed and altitude, and alert the controller if any deviations occur that require attention, air traffic controllers use ___.

• A. Real-time monitoring
• B. ERP
• C. Decision support systems (DSS)
• D. Expert systems

Answer: (C)

Decision support systems provide integrated analysis and alerting to help air traffic controllers maintain safe spacing. By pulling together real-time radar data, flight plans, weather, and aircraft performance models, a DSS continuously monitors airspeed and altitude, checks separation standards, and flags deviations that need attention. It not only displays data but also analyzes it and can suggest or guide corrective actions, making it more than just real-time monitoring. ERP is about business processes, not aviation safety, and expert systems are a different AI approach; while they can support decision-making, the established term for the ATC context is a decision support system because it combines data interpretation with actionable guidance and alerts.
