Narrative:
Upon landing rollout after a CAT III landing at about 80-90 KTS, a vehicle was spotted by me (the captain) near the centerline of my runway heading towards me (in dense fog). We were in fog, with ATIS reported WX of 1/8 mi visibility with freezing fog, and a ceiling of 100 ft partially obscured. Txwys and runways were also reported to be icy and slippery. Upon spotting the vehicle on landing rollout, I swerved slightly and increased braking even though I had braked heavily upon landing. At the same time I increased braking, my first officer yelled 'vehicle on runway!' the slight swerve (I could not swerve much because I did not want to risk runway departure on the slippery runway) and increased braking were enough to allow the vehicle time enough to see us and quickly dart off the runway at taxiway G which he luckily was right next to. As he darted onto taxiway G and our aircraft passed by him, we estimate we missed him by approximately 50 ft laterally. Ground radar was on and operating. We were never notified of any ground equipment being in our vicinity nor was there any mention of ground equipment on the ATIS. The tower controller told us by phone that the sand truck driver was cleared onto runway 6L, not runway 6R, and he apparently became disoriented and lost in the dense fog. The truck was on tower frequency. The controller also knew the truck was near runway 6R, but apparently failed to monitor the truck on radar and he entered runway 6R unchallenged by the tower controller.
Original NASA ASRS Text
Title: AN ACR MLG ON LNDG ROLLOUT FROM A CAT III APCH TO RWY 6R SAW AND AVOIDED A TRUCK THAT WAS ON THE RWY APPROX ONE THIRD OF THE WAY DOWN THE RWY. RVR WAS 1600 FT WITH TWR VISIBILITY AT ONE EIGHTH OF A MI. THE TRUCK WAS SUPPOSED TO BE ON RWY 6L AND APPARENTLY GOT CONFUSED IN THE FREEZING FOG. TWR ASDE WAS ON, BUT APPARENTLY THE LCL CTLR DID NOT SEE THE TRUCK ON THE RWY.
Narrative: UPON LNDG ROLLOUT AFTER A CAT III LNDG AT ABOUT 80-90 KTS, A VEHICLE WAS SPOTTED BY ME (THE CAPT) NEAR THE CTRLINE OF MY RWY HDG TOWARDS ME (IN DENSE FOG). WE WERE IN FOG, WITH ATIS RPTED WX OF 1/8 MI VISIBILITY WITH FREEZING FOG, AND A CEILING OF 100 FT PARTIALLY OBSCURED. TXWYS AND RWYS WERE ALSO RPTED TO BE ICY AND SLIPPERY. UPON SPOTTING THE VEHICLE ON LNDG ROLLOUT, I SWERVED SLIGHTLY AND INCREASED BRAKING EVEN THOUGH I HAD BRAKED HEAVILY UPON LNDG. AT THE SAME TIME I INCREASED BRAKING, MY FO YELLED 'VEHICLE ON RWY!' THE SLIGHT SWERVE (I COULD NOT SWERVE MUCH BECAUSE I DID NOT WANT TO RISK RWY DEP ON THE SLIPPERY RWY) AND INCREASED BRAKING WERE ENOUGH TO ALLOW THE VEHICLE TIME ENOUGH TO SEE US AND QUICKLY DART OFF THE RWY AT TXWY G WHICH HE LUCKILY WAS RIGHT NEXT TO. AS HE DARTED ONTO TXWY G AND OUR ACFT PASSED BY HIM, WE ESTIMATE WE MISSED HIM BY APPROX 50 FT LATERALLY. GND RADAR WAS ON AND OPERATING. WE WERE NEVER NOTIFIED OF ANY GND EQUIP BEING IN OUR VICINITY NOR WAS THERE ANY MENTION OF GND EQUIP ON THE ATIS. THE TWR CTLR TOLD US BY PHONE THAT THE SAND TRUCK DRIVER WAS CLRED ONTO RWY 6L, NOT RWY 6R, AND HE APPARENTLY BECAME DISORIENTED AND LOST IN THE DENSE FOG. THE TRUCK WAS ON TWR FREQ. THE CTLR ALSO KNEW THE TRUCK WAS NEAR RWY 6R, BUT APPARENTLY FAILED TO MONITOR THE TRUCK ON RADAR AND HE ENTERED RWY 6R UNCHALLENGED BY THE TWR CTLR.
