What capability does Precision Runway Monitor (PRM) provide?

• A. Monitoring runway surface conditions.
• B. Providing only VFR guidance on final.
• C. Simultaneous, independent IFR approaches at airports with closely spaced parallel runways.
• D. Predicting weather on final approach.

Answer: (C)

PRM is about increasing airport capacity by allowing two independent IFR approaches to closely spaced parallel runways at the same time. It uses enhanced radar surveillance and controller displays to track each aircraft on its own final approach path, so both can be guided and separated safely as they descend toward the runway. This setup provides the controller with accurate, separate situational awareness for both approaches, enabling simultaneous arrivals without sacrificing safety.

It’s not about monitoring runway surface conditions, it doesn’t provide only VFR guidance on final, and it doesn’t predict weather on final.
