What is the function of the MSSR plot processor?

• A. Filters noise
• B. Displays azimuth and range data
• C. Groups replies from all reachable aircraft simultaneously and produces a compiled digitized report
• D. Produces a separate report for each aircraft

Answer: (C)

The main function of the MSSR plot processor is to collect all transponder replies from every aircraft in range during a scan, decode that information, and produce a single compiled digitized report that represents all targets. This allows the system to present a cohesive set of data for plotting and tracking multiple aircraft at once. It isn’t primarily about filtering noise or producing separate reports for each aircraft; those tasks are handled by other parts of the system. The plot processor’s value is in gathering and digitizing the full set of responses so the display can show every aircraft accurately and in a synchronized way.
