FLC DEV IN MAKING IAP ILS APCH CAT I DURING CAT II ARPT WX MINS.

Narrative

WE WERE VECTORED FOR AN APCH TO 6R. THE APCH HAD BEEN BRIEFED; NAVAIDS TUNED AND IDENTED. THE RVR WAS RPTED AT 1800-2000 VARIABLE. WE WERE GOING TO DO A COUPLED APCH THE FO FLYING TO D/H; THE CAPT LNDG. AT A POINT WE THOUGHT WAS CLOSE TO INTERCEPT; THE CTLR SAID 'SWITCH TO 6L; GAVE THE FREQ;' AND CLRED US FOR THE APCH. WE WERE INTERCEPTING BY THE TIME WE GOT THE RADIOS TUNED AND IDENTED. IN THE BACK OF MY MIND I REMEMBERED 2000 RVR; SO IT MUST BE OK FOR CATEGORY 1 ILS. WE GOT PRETTY BUSY FROM POINT OF INTERCEPT TO LNDG; SO NO THOUGHT WAS GIVEN TO FURTHER CHKS. AT D/H THE RWY WAS IN SIGHT AND A LNDG WAS COMPLETED. ONLY AFTERWARD DID I CHK THE REQUIRED RVR BOX ON THE APCH PLATE; AND DISCOVERED IT WAS 2600 FT. CONTRIBUTING FACTORS: CTLR SWITCHED THE APCH TOO LATE. THE CREW WAS TOO RUSHED TO COMPLETE THE REQUIRED CHKS. FUEL STATE WAS GETTING CLOSE TO DIVERTING. CORRECTIVE ACTION: NEVER SWITCH HORSES IN MIDSTREAM. THIS WAS A POOR JOB OF COCKPIT RESOURCE MGMNT ON MY PART. FIRST; I SHOULD NOT HAVE ACCEPTED THE LATE SWITCH IN RWYS. SECOND; IF I DID; WE SHOULD HAVE GONE AROUND FOR ANOTHER VECTOR TO APCH TO SET UP BETTER. WHEN YOU ARE RUSHED; YOU'RE GOING TO MAKE MISTAKES AND THIS WAS A GOOD ILLUSTRATION OF THAT.
