Narrative:

A B747 was shipped to me on a SID at which time I climbed him and turned him on course. When the B747 was out of a safe altitude with no more conflicts; I issued the center frequency at which time the B747 pilot informed me they had received a TCAS (no RA) and asked about our terminal separation requirements. I informed the pilot that the aircraft was VFR and maintaining visual separation and was also on a VFR route which keeps them clear of departing aircraft. I also advised of basic terminal radar separation between VFR and IFR aircraft. The pilot switched frequencies without any other questions. On review of the tapes; the VFR had been issued traffic and had the heavy in sight; the heavy had been issued traffic and they had the VFR in sight. Have some sort of information passed on to pilots explaining separation requirements.

Title: A11 Controller described a TCAS event between an IFR air carrier departure and a VFR overflight; both with each other in sight and visual separation standards being applied; the reporter suggesting flight crews be better informed as ATC requirements.
