Narrative:

On an ILS to runway 1R at iad, airport was snow covered with braking action advisories in effect. Due to a snow packed runway and drifting snow, the runway was difficult to discern. However, one 30-40 ft path was plowed down to the pavement. There was no mention of this on the ATIS. When checked with the localizer, this path that ran for the length of the runway appeared to have been plowed on the centerline, as expected. With the all white environment, no approach lights on and runway edge lights mostly covered in snow, there wasn't much else to reference except the centered localizer. After the mains touched and speed brakes extended, my so was the first to realize that we were on the very left edge of the runway, where the path was plowed. We averted any runway lights and eased the aircraft back towards the 'center' of the runway. Braking action was fair. Taxiing in, I advised the tower of this deceiving condition. I feel the fact that we had a 10 hour duty day and being very fatigued due to the fact we had been up all night had considerable effect on this incident.

Title: B727 FLC LANDS ON CLRED RWY AREA ONLY TO DISCOVER IT IS NOT ON CTRLINE BUT TO THE L.

Narrative: ON AN ILS TO RWY 1R AT IAD, ARPT WAS SNOW COVERED WITH BRAKING ACTION ADVISORIES IN EFFECT. DUE TO A SNOW PACKED RWY AND DRIFTING SNOW, THE RWY WAS DIFFICULT TO DISCERN. HOWEVER, ONE 30-40 FT PATH WAS PLOWED DOWN TO THE PAVEMENT. THERE WAS NO MENTION OF THIS ON THE ATIS. WHEN CHKED WITH THE LOC, THIS PATH THAT RAN FOR THE LENGTH OF THE RWY APPEARED TO HAVE BEEN PLOWED ON THE CTRLINE, AS EXPECTED. WITH THE ALL WHITE ENVIRONMENT, NO APCH LIGHTS ON AND RWY EDGE LIGHTS MOSTLY COVERED IN SNOW, THERE WASN'T MUCH ELSE TO REF EXCEPT THE CTRED LOC. AFTER THE MAINS TOUCHED AND SPD BRAKES EXTENDED, MY SO WAS THE FIRST TO REALIZE THAT WE WERE ON THE VERY L EDGE OF THE RWY, WHERE THE PATH WAS PLOWED. WE AVERTED ANY RWY LIGHTS AND EASED THE ACFT BACK TOWARDS THE 'CTR' OF THE RWY. BRAKING ACTION WAS FAIR. TAXIING IN, I ADVISED THE TWR OF THIS DECEIVING CONDITION. I FEEL THE FACT THAT WE HAD A 10 HR DUTY DAY AND BEING VERY FATIGUED DUE TO THE FACT WE HAD BEEN UP ALL NIGHT HAD CONSIDERABLE EFFECT ON THIS INCIDENT.
