Which statement about PRCS is true?

• A. One PRCS can control three LPWS.
• B. PRCS can control two LPWS.
• C. One PRCS can control four LPWS.
• D. PRCS is used for training.

Answer: (B)

The main idea here is how many LPWS units a single PRCS is designed to manage. In typical configurations, a PRCS is built to oversee two LPWS at once, handling the control commands, status monitoring, and basic fault management for those two devices. Trying to connect more than two would exceed the controller’s intended capacity and could complicate communication and reliability. The option about training isn’t the function of PRCS, so it isn’t the true statement. So, a single PRCS controlling two LPWS best fits the expected spec.
