THE FLC LANDS WITH RVV ONE FOURTH MI FOR THEIR RWY 30 AND PREVAILING VISIBILITY ONE HALF MI. THE MINIMUMS ARE ONE HALF MI AND THE CREW LANDED ON THE BASIS OF THE PREVAILING VISIBILITY.

Narrative

I WAS THE FO AND PF ON APCH INTO BAKERSFIELD; CA. WE WERE ON VECTORS FOR THE ILS DME RWY 30R BFL. CURRENT SEQUENCE RPTS STATED WX WAS CEILING 100 FT OVCST VISIBILITY 1/2 MI. WE RECEIVED OUR FINAL VECTOR TO JOIN THE LOC OUTSIDE THE FINAL APCH FIX. ADDITIONALLY; THE CTLR STATED RVV FOR RWY '30R' WAS 1/4 MI. I STATED TO THE CAPT THAT I FELT WE COULD NOT ACCEPT THE APCH CLRNC BASED ON THIS 'RVV RPT' AND STILL BEING OUTSIDE THE FAF. TO BE TOTALLY HONEST HOWEVER; I WAS NOT SURE ABOUT THIS BECAUSE I HAVE NEVER RECEIVED AN RVV RPT (IT WAS ALWAYS RVR). I KNEW RVR IS CTLING OVER PREVAILING VISIBILITY BUT I WAS UNSURE IF RVV WAS CTLING. THE CAPT STATED HE WAS CONFIDENT WE COULD ACCEPT THIS APCH BASED ON 1/2 MI PREVAILING VISIBILITY AND THAT THE RVV WAS NOT CTLING. AT THIS POINT I AGREED WITH THE CAPT AND WE TOOK THE APCH. AT THE COMPLETION OF MY SHIFT I REFERRED TO THE AIRMAN'S INFO MANUAL TO FIND THAT RVV IS INDEED CTLING OVER PREVAILING VISIBILITY AND THAT WE SHOULD HAVE NOT ACCEPTED THE APCH CLRNC. ALTHOUGH I REGULARLY REVIEW THE 'AIM;' APPARENTLY I DO NOT REVIEW IT REGULARLY ENOUGH!
