Narrative:
Approaching dfw; we were cleared direct morry to intercept the runway 13R localizer; descend to 4000 ft; and maintain best forward speed. Inside morry approach held us up due to air carrier traffic downwind to alliance. Upon visually acquiring the traffic we were then cleared the visual to runway 13R. This set up a high; fast start to the approach. The first officer flying was high time and extremely competent; therefore I had no reservations about continuing the approach. Upon switching tower they recognized our high state and authority/authorized us an s-turn to the right. At that point we also realized we had a 22 KT quartering tailwind; opposed to the calm conditions reported on the ground; adding to our difficulties. Upon completing our s-turn and approaching 1000 ft AGL we found ourselves on the GS but still fast. Tower cleared us to land. At 500 ft we were still on GS but surprisingly fast with the power back. The wind was now decreasing. We elected to continue to land due to the good WX conditions; long dry runway; and the prospect of going around in close to the runway 36R/left traffic. The touchdown was exceptional and well within the touchdown zone with a normal rollout using minimal braking. In retrospect; I made a poor decision allowing the approach to begin with a high fast start. The wind then put us out of the guidelines for a stable VFR approach also pushing the flap confign speed limits so much emphasized in our recent training.

Title: MD80 FLT CREW HAS AN UNSTABILIZED APCH TO DFW.
Narrative: APCHING DFW; WE WERE CLRED DIRECT MORRY TO INTERCEPT THE RWY 13R LOC; DSND TO 4000 FT; AND MAINTAIN BEST FORWARD SPD. INSIDE MORRY APCH HELD US UP DUE TO ACR TFC DOWNWIND TO ALLIANCE. UPON VISUALLY ACQUIRING THE TFC WE WERE THEN CLRED THE VISUAL TO RWY 13R. THIS SET UP A HIGH; FAST START TO THE APCH. THE FO FLYING WAS HIGH TIME AND EXTREMELY COMPETENT; THEREFORE I HAD NO RESERVATIONS ABOUT CONTINUING THE APCH. UPON SWITCHING TWR THEY RECOGNIZED OUR HIGH STATE AND AUTH US AN S-TURN TO THE R. AT THAT POINT WE ALSO REALIZED WE HAD A 22 KT QUARTERING TAILWIND; OPPOSED TO THE CALM CONDITIONS RPTED ON THE GND; ADDING TO OUR DIFFICULTIES. UPON COMPLETING OUR S-TURN AND APCHING 1000 FT AGL WE FOUND OURSELVES ON THE GS BUT STILL FAST. TWR CLRED US TO LAND. AT 500 FT WE WERE STILL ON GS BUT SURPRISINGLY FAST WITH THE PWR BACK. THE WIND WAS NOW DECREASING. WE ELECTED TO CONTINUE TO LAND DUE TO THE GOOD WX CONDITIONS; LONG DRY RWY; AND THE PROSPECT OF GOING AROUND IN CLOSE TO THE RWY 36R/L TFC. THE TOUCHDOWN WAS EXCEPTIONAL AND WELL WITHIN THE TOUCHDOWN ZONE WITH A NORMAL ROLLOUT USING MINIMAL BRAKING. IN RETROSPECT; I MADE A POOR DECISION ALLOWING THE APCH TO BEGIN WITH A HIGH FAST START. THE WIND THEN PUT US OUT OF THE GUIDELINES FOR A STABLE VFR APCH ALSO PUSHING THE FLAP CONFIGN SPD LIMITS SO MUCH EMPHASIZED IN OUR RECENT TRAINING.
