<< >> NASA ASRS Report 186294, August 1991

ATIS and approach gave visibility below landing mins for flight crew. Looking at chart flight crew thought they were legal but were looking at 36L at cvg instead of runway cleared to 36R. Continuing approach WX given as legal for 36R and flight crew landed 36R.

Narrative:

Cvg ATIS giving 3 mi visibility, runway 18, turned over to approach control and advised we were going to 36R for 'north operation' no other explanation, even though we passed over traffic for 18. No other traffic in front or behind us. Turning final we were advised 'visibility was 1/4 mi, state intentions.' attempting turn, on change of PF, turning on autoplt, and autoplt failure to capture GS we mistook 36L CAT ii procedures for 36R (facing chart page) and continued approach. 2 calls to tower finally got WX of (legal) 3/4 mi visibility. Runway was visible at all times. We saw it at 8 DME when tower called 1/4 mi visibility. We began approach when visibility below mins by mistaking 36L procedures for CAT ii for 36R and rushed change of PF and autoplt failure.

Title: ATIS AND APCH GAVE VIS BELOW LNDG MINS FOR FLC. LOOKING AT CHART FLC THOUGHT THEY WERE LEGAL BUT WERE LOOKING AT 36L AT CVG INSTEAD OF RWY CLRED TO 36R. CONTINUING APCH WX GIVEN AS LEGAL FOR 36R AND FLC LANDED 36R.

Narrative: CVG ATIS GIVING 3 MI VISIBILITY, RWY 18, TURNED OVER TO APCH CTL AND ADVISED WE WERE GOING TO 36R FOR 'N OP' NO OTHER EXPLANATION, EVEN THOUGH WE PASSED OVER TFC FOR 18. NO OTHER TFC IN FRONT OR BEHIND US. TURNING FINAL WE WERE ADVISED 'VISIBILITY WAS 1/4 MI, STATE INTENTIONS.' ATTEMPTING TURN, ON CHANGE OF PF, TURNING ON AUTOPLT, AND AUTOPLT FAILURE TO CAPTURE GS WE MISTOOK 36L CAT II PROCS FOR 36R (FACING CHART PAGE) AND CONTINUED APCH. 2 CALLS TO TWR FINALLY GOT WX OF (LEGAL) 3/4 MI VISIBILITY. RWY WAS VISIBLE AT ALL TIMES. WE SAW IT AT 8 DME WHEN TWR CALLED 1/4 MI VISIBILITY. WE BEGAN APCH WHEN VISIBILITY BELOW MINS BY MISTAKING 36L PROCS FOR CAT II FOR 36R AND RUSHED CHANGE OF PF AND AUTOPLT FAILURE.
