Question about LARS in the UK

[Talkdownman]

Guidelines for the provision of TS from AIC: Y 106/2012:

Traffic is normally considered to be relevant when, in the judgement of the controller, the conflicting aircraft's observed flight profile indicates that it will pass within 3 NM and, where level information is available, 3000 ft of the aircraft in receipt of the Traffic Service.

There were no such guidelines under RIS. Some traffic information under RIS from some ATSOCA ATCOs was akin to an opthalmic examination.
