What is Approach RADAR used for?

• A. To guide aircraft to safe landing in zero visibility conditions
• B. To guide ships in fog
• C. To locate submarines
• D. To track weather systems

Answer: (A)

Approach radar is used to guide aircraft during the approach and landing phase, especially in instrument meteorological conditions. It provides the controller with precise information about an aircraft’s position and motion and allows them to give accurate azimuth and elevation guidance or radar vectors to bring the aircraft onto the final approach path and glide toward the runway, enabling a safe landing when visibility is zero or severely reduced. This differs from maritime radar used to guide ships in fog, sonar used to locate submarines, or weather radar used to track precipitation and storms.
