notdavegorman. The procedures will vary depending on the class of airspace. In Class A (where I lived) full separation is provided between IFR and IFR and between IFR and SVFR traffic. The only circumstance where that varied was "in the vicinity of an aerodrome" where an aircraft on a visual approach following another aircraft may be given traffic info and told to follow it. However, both aircraft would still be operating under IFR.
