Narrative:

On a VFR approach to san approximately 25 NM northeast of the airport we were given a vector heading 190 degrees for the intercept of localizer runway 27 approach and 4000 ft. Upon leveling 4000 ft and approximately 16 DME socal approach cleared us to turn right heading 250 degrees and descend to 3800 ft cleared runway 27 localizer approach. When turning inbound we received a GPWS warning 'terrain, terrain, whoop, whoop, pull up.' I responded and climbed to 4500 ft to silence the GPWS warning. His response was that it happens very often and that because we were level at 4000 ft he didn't think we would get the warning. We then finished the approach. In retrospect maybe a notation in the part 2 may be in order of possible GPWS warnings in the area.

Title: SUPER MD80 MAINTAINING 4000 FT ON VECTOR TO RWY 27. CLRED DSND TO 3800 FT AND CLRED RWY 27 APCH. GOT GPWS AND EXECUTED CLB TO 4500 FT. CTLR REMARKS HAPPENS FREQUENTLY.

Narrative: ON A VFR APCH TO SAN APPROX 25 NM NE OF THE ARPT WE WERE GIVEN A VECTOR HDG 190 DEGS FOR THE INTERCEPT OF LOC RWY 27 APCH AND 4000 FT. UPON LEVELING 4000 FT AND APPROX 16 DME SOCAL APCH CLRED US TO TURN R HDG 250 DEGS AND DSND TO 3800 FT CLRED RWY 27 LOC APCH. WHEN TURNING INBOUND WE RECEIVED A GPWS WARNING 'TERRAIN, TERRAIN, WHOOP, WHOOP, PULL UP.' I RESPONDED AND CLBED TO 4500 FT TO SILENCE THE GPWS WARNING. HIS RESPONSE WAS THAT IT HAPPENS VERY OFTEN AND THAT BECAUSE WE WERE LEVEL AT 4000 FT HE DIDN'T THINK WE WOULD GET THE WARNING. WE THEN FINISHED THE APCH. IN RETROSPECT MAYBE A NOTATION IN THE PART 2 MAY BE IN ORDER OF POSSIBLE GPWS WARNINGS IN THE AREA.
