What does the acronym ASR stand for in aviation?

The acronym ASR in aviation stands for Air Surveillance Radar. This type of radar system is crucial for air traffic control and military operations, as it enables the detection and tracking of aircraft within specific airspace. Air Surveillance Radar provides situational awareness, helping controllers monitor the movement of aircraft, ensuring safety, and facilitating the management of both civilian and military air traffic.

The other options, while they may sound relevant, do not accurately represent the commonly accepted terminology in aviation. Aircraft Safety Readiness, Advanced Sensor Report, and Aircraft System Response are not typically used terms associated with air traffic control or surveillance systems in the aviation context. Understanding the role and function of Air Surveillance Radar helps clarify its importance in maintaining safe and efficient airspace operations.
