Narrative:

Jan/92 flight was inbound to san jose from fresno. Approximately 18 DME from sjc, bay approach control instructed flight to intercept the 30L localizer, maintain 4000 ft until established and cleared us for the approach. The current ATIS reported the WX as above landing mins. Prior to turning the flight over to san jose tower, the RVR for 30L was reported at 6000 ft. At approximately 12 DME bay approach turned the flight over to tower. At approximately 10 DME san jose tower cleared flight to land on runway 30L and reported RVR of 4000 ft. At this time the aircraft was established on the localizer and GS. At approximately 6 DME tower reported RVR of 3000 ft and decreasing. At approximately 5 DME tower reported RVR of 2400. At approximately 4 DME tower reported RVR of 2200. The approach was continued even though RVR 2400 is required to begin the ILS to runway 30L. At approximately 2 to 3 DME RVR 1800 was reported by the tower. When decision height was reached, the approach lights were visible. A descent to 100 ft above the runway was continued and the runway end identifier lights were visible. Landing on runway 30L was then executed without incident. This report is submitted to clarify any question that may arise concerning possibly landing when RVR was reported below 2400 ft. The profile view for the ILS to 30L at sjc does not have a 'final approach fix'. The approach was continued when RVR of 2400 ft was reported because the aircraft, at that time, was inside 5 DME and established on the localizer and GS.

Title: COMMUTER SMT CONTINUED IAP ILS APCH TO SJC IN DETERIORATING VISIBILITY CONDITIONS. AT TIME OF LNDG THE SURFACE VISIBILITY WAS BELOW ARPT LNDG MINS.

Narrative: JAN/92 FLT WAS INBOUND TO SAN JOSE FROM FRESNO. APPROX 18 DME FROM SJC, BAY APCH CTL INSTRUCTED FLT TO INTERCEPT THE 30L LOC, MAINTAIN 4000 FT UNTIL ESTABLISHED AND CLRED US FOR THE APCH. THE CURRENT ATIS RPTED THE WX AS ABOVE LNDG MINS. PRIOR TO TURNING THE FLT OVER TO SAN JOSE TWR, THE RVR FOR 30L WAS RPTED AT 6000 FT. AT APPROX 12 DME BAY APCH TURNED THE FLT OVER TO TWR. AT APPROX 10 DME SAN JOSE TWR CLRED FLT TO LAND ON RWY 30L AND RPTED RVR OF 4000 FT. AT THIS TIME THE ACFT WAS ESTABLISHED ON THE LOC AND GS. AT APPROX 6 DME TWR RPTED RVR OF 3000 FT AND DECREASING. AT APPROX 5 DME TWR RPTED RVR OF 2400. AT APPROX 4 DME TWR RPTED RVR OF 2200. THE APCH WAS CONTINUED EVEN THOUGH RVR 2400 IS REQUIRED TO BEGIN THE ILS TO RWY 30L. AT APPROX 2 TO 3 DME RVR 1800 WAS RPTED BY THE TWR. WHEN DECISION HEIGHT WAS REACHED, THE APCH LIGHTS WERE VISIBLE. A DSCNT TO 100 FT ABOVE THE RWY WAS CONTINUED AND THE RWY END IDENTIFIER LIGHTS WERE VISIBLE. LNDG ON RWY 30L WAS THEN EXECUTED WITHOUT INCIDENT. THIS RPT IS SUBMITTED TO CLARIFY ANY QUESTION THAT MAY ARISE CONCERNING POSSIBLY LNDG WHEN RVR WAS RPTED BELOW 2400 FT. THE PROFILE VIEW FOR THE ILS TO 30L AT SJC DOES NOT HAVE A 'FINAL APCH FIX'. THE APCH WAS CONTINUED WHEN RVR OF 2400 FT WAS RPTED BECAUSE THE ACFT, AT THAT TIME, WAS INSIDE 5 DME AND ESTABLISHED ON THE LOC AND GS.
