Narrative

LOCATION: INTERCEPTING LOC RWY 27 APCH; N OF LOC WHILE ON A HEADING TO INTERCEPT THE LOC FOR RWY 27 AT SAN. GPWS; 'TERRAIN; TERRAIN' SOUNDED. I WAS HAND-FLYING AND IMMEDIATELY ADDED PWR AND STARTED TO CLB. WARNING CEASED AT APPROX 4400 FT. WE WERE APPROX 2 DME OUTSIDE OF SWATT INTXN (12.6 DME ON LOC DME). WE WERE STILL IN A GOOD POS BASED ON DME AND ALT TO CONTINUE THE APCH THEREFORE WE CONTINUED UNEVENTFULLY. I CALLED SOCAL APCH LATER ON THE PHONE AND FOUND OUT THE WARNING WAS NOT TOO UNCOMMON. THE MVA IS 3800 FT AND THE HILL WE PASSED OVER WAS 2791 FT. UPON LOOKING BACK AT THE SIT I REALIZED THE FO TOLD THE CTLR TO STANDBY WHEN HE CLRED US FOR THE APCH DURING THE MIDDLE OF THE WARNING SOUNDING. WE SHOULD HAVE TOLD THE CTLR AT THE TIME THAT WE WERE RESPONDING TO A GPWS. WE WERE THE ONLY ACFT HE WAS WORKING AS HE HAD TOLD US THIS A FEW MINS PRIOR. THEREFORE I DO NOT BELIEVE TFC WAS A FACTOR. I WOULD IN THE FUTURE MAKE SURE THAT ATC KNEW WHAT WE WERE DOING MUCH SOONER. ALSO AFTER TALKING TO SOCAL APCH IT SOUNDED LIKE RAISING THE MVA TO 4000 FT WOULD TAKE CARE OF THIS IN THE FUTURE. I PERSONALLY WILL NOT ACCEPT 3800 FT UNTIL ON THE LOC NEXT TIME. THE CTLR STATED THAT THE APCH PROFILE IS STEEP ENOUGH WITHOUT AN ADDITIONAL 200 FT ADDED TO IT. I THINK THE APCH IS EVEN STEEPER WITH A GPWS ESCAPE MANEUVER ADDED TO IT.
