Which radar approach type provides azimuth and elevation guidance?

• A. ASR
• B. NDB
• C. VOR
• D. PAR

Answer: (D)

The main idea is a radar approach that guides the aircraft both laterally and vertically. Precision Approach Radar provides this by having a radar operator track the plane and give exact azimuth (left-right) and elevation (up-down) guidance, helping the pilot fly a precise path to the runway in instrument conditions. Other systems don’t offer this combination: ASR is for general surveillance and won’t provide the framed, real-time approach cues to the pilot; NDB gives bearing to a beacon without radar tracking or vertical guidance; VOR gives azimuth (and with DME distance) but still lacks radar-based elevation guidance. So, only where both azimuth and elevation guidance are provided is the approach type that uses radar to guide the pilot precisely to a landing.
