PRM stands for what system?

• A. Primary Runway Monitor
• B. Precision Runway Monitor
• C. Pilot Resource Module
• D. Performance Runway Management

Answer: (B)

The concept being tested is runway surveillance with high precision for safe parallel runway operations. The system called Precision Runway Monitor provides near real-time, highly accurate tracking of aircraft on final approach and in the runway environment, giving air traffic control a precise picture of where each aircraft is. That precise situational awareness helps controllers manage sequencing, spacing, and potential conflicts near runways, which is essential for safe use of parallel approaches. This is why Precision Runway Monitor is the best answer: it is the established name and function of the system used for this purpose. The other terms don’t correspond to a recognized ATC surveillance system—Primary Runway Monitor isn’t a standard term, Pilot Resource Module sounds pilot-focused, and Performance Runway Management isn’t a standard system name in airway operations.
