Narrative:

Received numerous vectors for alignment to roslyn lda runway 18 at dca. I believe WX was reported as 25 scattered or broken 40 overcast. We were cleared for roslyn lda to runway 18. We were lined up on 147 degree radial of dca outside of maudy at 3000 and still no contact with ground. Crossed maudy at 3000 and descended to minie at 2000'. Crossed minie at 2000 and still no ground contact. Then descended to minimums of 1100'. Right at 1100' and outside the 3.5 DME, we broke out of the bottom of a cloud deck. I notified tower that the WX had deteriorated to 1100' and visibility seemed ok but not good. The runway was directly ahead and we were in the slot. We continued to approach. As we crossed the numbers on the runway, I noticed it was runway 15. I did not call go-around because we were already in the flare and the runway was sufficient in length for our landing weight. Also, there was no conflicting traffic.

Title: MLG FLT CREW LANDS WRONG RWY AT DCA.

Narrative: RECEIVED NUMEROUS VECTORS FOR ALIGNMENT TO ROSLYN LDA RWY 18 AT DCA. I BELIEVE WX WAS REPORTED AS 25 SCATTERED OR BROKEN 40 OVERCAST. WE WERE CLRED FOR ROSLYN LDA TO RWY 18. WE WERE LINED UP ON 147 DEG RADIAL OF DCA OUTSIDE OF MAUDY AT 3000 AND STILL NO CONTACT WITH GND. CROSSED MAUDY AT 3000 AND DSNDED TO MINIE AT 2000'. CROSSED MINIE AT 2000 AND STILL NO GND CONTACT. THEN DESCENDED TO MINIMUMS OF 1100'. RIGHT AT 1100' AND OUTSIDE THE 3.5 DME, WE BROKE OUT OF THE BOTTOM OF A CLOUD DECK. I NOTIFIED TWR THAT THE WX HAD DETERIORATED TO 1100' AND VISIBILITY SEEMED OK BUT NOT GOOD. THE RWY WAS DIRECTLY AHEAD AND WE WERE IN THE SLOT. WE CONTINUED TO APCH. AS WE CROSSED THE NUMBERS ON THE RWY, I NOTICED IT WAS RWY 15. I DID NOT CALL GO-AROUND BECAUSE WE WERE ALREADY IN THE FLARE AND THE RWY WAS SUFFICIENT IN LENGTH FOR OUR LNDG WEIGHT. ALSO, THERE WAS NO CONFLICTING TFC.
