What is the maximum number of tracked aircraft the AN/TPN-25 Precision Approach Radar (PAR) can process at one time?

The correct answer is based on the specifications of the AN/TPN-25 Precision Approach Radar (PAR), which has been designed to process up to six tracked aircraft simultaneously. This capability allows the radar to efficiently manage multiple aircraft during landing operations, enhancing situational awareness for air traffic controllers and improving overall safety in busy airspace.

The system's ability to track six aircraft at a time is critical for optimizing landing sequences and minimizing the risk of mishaps, especially in complex air traffic environments. The radar's advanced technology ensures that each aircraft can be observed in real-time, maintaining accurate positional information, which is essential for guiding aircraft safely to the runway.

Other options suggest higher numbers, which do not align with the operational parameters specified for the AN/TPN-25. Such discrepancies illustrate the importance of understanding the technical specifications and operational limits of radar systems in aviation.
