Radar Information Service
From SKYbrary Wiki
Radar Information Service (RIS) is a service provided as an adjunct to a Flight Information Service. An RIS may provide identified aircraft with:
- a) information regarding any aircraft observed to be on a conflicting path with the radar-identified aircraft and suggestions or advice regarding avoiding action;
- b) information on the position of significant weather and, as practicable, advice to the aircraft on how best to circumnavigate any such areas of adverse weather
- c) information to assist the aircraft in its navigation.
