What are the two types of radar approaches?

• A. NDB and VOR
• B. PAR and ASR
• C. GPS and ILS
• D. DME and LORAN

Answer: (B)

Radar approaches are guided by ATC using ground-based radar. There are two main forms of radar approach: Precision Approach Radar, which gives the controller azimuth and elevation guidance to lead you along a precise approach path to the runway, and Airport Surveillance Radar approaches, where radar surveillance supports approach control to vector you to the final approach and provide altitudes and headings to bring you in, but without a precise glidepath.

Other options involve navigation aids that don’t rely on radar guidance for the approach, such as NDB or VOR, or systems like GPS and ILS that are not categorized as radar approaches.
