Which radar is used for military precision approach?

• A. Precision Runway Monitoring
• B. Precision Approach Radar
• C. Airport Surface Detection Equipment
• D. Air Route Surveillance Radar

Answer: (B)

Precision Approach Radar is the radar system that provides real-time azimuth and elevation guidance to a controller so they can steer a military aircraft along a precise approach path to the runway and guide the landing. The controller uses the PAR display to keep the airplane aligned with the runway centerline and on the correct glide path, ensuring a controlled, accurate approach even when other navigation aids aren’t available or reliable. This direct guidance during the final approach is what makes it the choice for military precision approach operations.

The other systems serve different roles: Precision Runway Monitoring supports safe sequencing and separation on closely spaced parallel runways, not guiding the landing path itself; Airport Surface Detection Equipment monitors aircraft and vehicles on the ground to prevent incursions; Air Route Surveillance Radar tracks aircraft along en-route airways, not during the final approach to a single runway.
