In 1961, the radar system at Sydney Airport was an early civil aviation radar designed to enhance air traffic control and safety. It provided pilots with the ability to avoid hazardous weather and assisted air traffic controllers in defining aircraft positions with precision. The radar was crucial for monitoring and managing air traffic, especially in poor visibility conditions. While specific details on the radar's capabilities in 1961 are limited, it played a significant role in the airport's operations and contributed to the safety and efficiency of flights during that period. For more detailed information, you can refer to sources like the Wikipedia page on Ansett-ANA Flight 325, which mentions the radar system's installation in the control tower that year, or the report on civil air traffic services in Australia by Airservices Australia.Ansett-ANA Flight 325 - Wikipedia
