ARPT WX MINS FOR APCH NOT COMPLIED WITH.

Narrative

AFTER EXECUTING A MISSED APCH ON RWY 11R AT MINNEAPOLIS (WE SAW THE APCH LIGHTS ABOUT THE SAME TIME WE STARTED THE MISSED APCH); WE WERE BEING VECTORED FOR ANOTHER APCH TO RWY 11R. THE RVR WAS FLUCTUATING UP AND DOWN FREQUENTLY BTWN 6500 FT AND 4500 FT. I MADE THE DECISION TO EXECUTE AN AUTOLAND APCH AND LNDG WITH THE COPLT FLYING (THE SECOND APCH). HE HAD 3 1/2 YRS EXPERIENCE IN THE ACFT AND I WAS FLYING MY 4TH LEG AFTER COMPLETING IOE THE PREVIOUS WK. WE ALSO AGREED THAT WE WOULD DEPART MSP FOR MKE (OUR ALTERNATE) IF WE COULD NOT LAND ON THIS APCH. WE RECEIVED AN RVR RPT OF 6000 FT SHORTLY BEFORE THE FINAL APCH FIX OF KINNS; WITH THE ACFT CONFIGURED FOR THE AUTOLAND APCH; GS AND LOC CAPTURED. SHORTLY THEREAFTER WE RECEIVED AN RVR RPT OF 3000 FT. THE RVR REQUIRED FOR THE APCH IS 2400 FT; BUT WE WERE USING 5000 FT AND A DH OF 1141 FT IN KEEPING WITH THE HIGH MINS REQUIREMENT OF 300 FT AND 1 MI. WHEN THE CTLR GAVE THE 3000 FT RVR RPT WE WERE ENGAGED ON THE APCH; VERY CLOSE TO THE FINAL APCH FIX AND SINCE THE RVR WAS ABOVE PUBLISHED MINS OF 2400 FT AND FLUCTUATING RAPIDLY I ELECTED TO CONTINUE THE APCH. WE ACQUIRED THE SEQUENCED FLASHERS AT ABOUT 350 FT AND THE THRESHOLD AT 200 FT AND LANDED. AFTER REREADING THE COMPANY MANUAL I STILL THINK MY DECISION TO CONTINUE THE APCH WAS A GOOD ONE. THE 100 FT AND 1/2 MI ADDITION IS TO CALCULATE LNDG MINS AND THAT USING 2400 FT RVR TO CONTINUE THE APCH IS OK AS LONG AS THE 300 FT AND 1 MI CRITERIA FOR LNDG IS ADHERED TO.
