What type of service provides radar-derived information about traffic in the vicinity?

Traffic Service is the type of service that specifically provides radar-derived information about air traffic in the vicinity. This service is designed to enhance situational awareness for pilots and air traffic controllers by offering real-time data on nearby aircraft, which can significantly improve safety in the busy airspace.

By utilizing radar, Traffic Service enables controllers to monitor the positions and movements of aircraft, allowing them to provide timely and accurate information to pilots regarding potential traffic conflicts. This is especially important in congested areas where visual identification of other aircraft might not be feasible.

The focus on radar-derived information sets Traffic Service apart from other types of services, which may not necessarily provide real-time data or may have different functions in the air traffic management system. For instance, Alerting Service is primarily about notifying pilots of potential hazards, while Procedural Service involves communication and procedural coordination without relying on radar-derived information. Deconfliction Service aims at resolving conflicts but does not exclusively focus on providing real-time traffic information.
