Which of the following approaches is categorized as a precision approach?

• A. SDF
• B. LDA
• C. PAR
• D. ASR

Answer: (C)

A precision approach is defined by its use of precise lateral and vertical guidance to ensure safe and accurate landings. The Precision Approach Radar (PAR) falls into this category because it provides both azimuth and elevation guidance to the pilot during the final stages of approach and landing. This allows pilots to receive real-time information on their position and altitude relative to the runway, which significantly enhances safety, especially in low visibility conditions. In contrast, other approaches like the SDF (Simplified Directional Facility), LDA (Localizer-Type Directional Aid), and ASR (Airport Surveillance Radar) are not classified as precision approaches. While they can provide important navigational information, they do not offer the same level of vertical guidance that is critical for approaching landing maneuvers. The other options may assist with lateral guidance but lack the comprehensive vertical guidance that is a hallmark of a precision approach. Therefore, the PAR is recognized as a precision approach due to its dual guidance capabilities that help pilots make safe landings.
