Narrative:
During an ILS approach runway 30, reported visibility 6 mi in haze and smoke. Visibility lower to the southeast. We sighted the field at 1400 on the glide slope. At about 800' tower called 2 targets at 10 and 11 O'clock. After a delay, we sighted both targets. They were on a left visual downwind 25L supposedly at 1000. The first was obviously below that altitude. We continued the approach and landing without deviation from the approach. I question the practice at lgb of flying a VFR downwind over/through an ILS approach final when the aircraft on the ILS is under an IFR clearance. The procedure is predicated on the IFR aircraft sighting the VFR downwind traffic even though they are IFR. Additionally, we have been directed by the company to fly above the glide slope in the interest of noise abatement. The procedure also precludes an early go around by the aircraft on the instrument approach.

Title: ACFT ON DOWNWIND APCH TO INTERSECTING RWY CROSS THROUGH ILS APCH PATH OF REPORTER ACFT.
Narrative: DURING AN ILS APCH RWY 30, REPORTED VISIBILITY 6 MI IN HAZE AND SMOKE. VISIBILITY LOWER TO THE SE. WE SIGHTED THE FIELD AT 1400 ON THE GLIDE SLOPE. AT ABOUT 800' TWR CALLED 2 TARGETS AT 10 AND 11 O'CLOCK. AFTER A DELAY, WE SIGHTED BOTH TARGETS. THEY WERE ON A LEFT VISUAL DOWNWIND 25L SUPPOSEDLY AT 1000. THE FIRST WAS OBVIOUSLY BELOW THAT ALT. WE CONTINUED THE APCH AND LNDG WITHOUT DEVIATION FROM THE APCH. I QUESTION THE PRACTICE AT LGB OF FLYING A VFR DOWNWIND OVER/THROUGH AN ILS APCH FINAL WHEN THE ACFT ON THE ILS IS UNDER AN IFR CLRNC. THE PROC IS PREDICATED ON THE IFR ACFT SIGHTING THE VFR DOWNWIND TFC EVEN THOUGH THEY ARE IFR. ADDITIONALLY, WE HAVE BEEN DIRECTED BY THE COMPANY TO FLY ABOVE THE GLIDE SLOPE IN THE INTEREST OF NOISE ABATEMENT. THE PROC ALSO PRECLUDES AN EARLY GO AROUND BY THE ACFT ON THE INSTRUMENT APCH.
