Precision Approach Radar (PAR) is used to guide aircraft by providing what?

• A. Provide horizontal and vertical guidance with radar operator directing heading and descent.
• B. Provide only vertical guidance.
• C. Only used for enroute navigation.
• D. Only visual guidance on final approach.

Answer: (A)

Precision Approach Radar provides real-time guidance in two dimensions: horizontal and vertical. A radar operator tracks the aircraft and directs precise heading changes to keep it on the final approach course (horizontal guidance) and provides descent instructions to maintain the correct glide path (vertical guidance). This combination helps the pilot align with the runway and descend safely to the landing point. It’s not limited to vertical guidance, not used for enroute navigation, and not simply a visual cue on final approach, which is why the description of offering both horizontal and vertical guidance with the radar operator directing heading and descent is the best fit.
