How many aircraft can the PAR track simultaneously?

• A. Up to 4
• B. Up to 8
• C. Up to 6
• D. Up to 10

Answer: (C)

The concept being tested is how many targets a PAR can track reliably at the same time. A PAR provides precise azimuth and elevation guidance to each approaching aircraft, and keeping that guidance accurate requires dedicated updates for every tracked target. Because of the processing and display demands, there’s a practical limit to how many aircraft can be tracked simultaneously without degrading the quality of guidance. The best choice reflects this modest simultaneous-tracking capability, aligning with the system’s real-world constraint that you can handle a limited number of targets at once. The other options imply either too few or too many aircraft for dependable guidance, which would reduce accuracy or overwhelm the display and update rate.
