Radar Information Service (RIS) is a non-control service provided by air traffic controllers to alert pilots of aircraft that are in close proximity and potential conflict. This service enhances awareness and helps prevent collisions by providing additional surveillance information gathered from radar sources. RIS is not a replacement for vigilance and adherence to regulations by pilots.
