MD80 CREW ON APCH TO DFW RWY 13R REQUIRED 160 DEG HDG TO STAY ON LOC DUE TO STRONG XWIND MAY HAVE CONFUSED FINAL CTLR.

Narrative

WE WERE GIVEN; FROM WHAT I REMEMBER; INSTRUCTIONS TO INTERCEPT THE RWY 13R LOC AND MAINTAIN OUR SPD UNTIL MORRY AND THEN SLOW DOWN TO 170 KTS UNTIL THE OM. WE WERE AT 170 KTS OVER MORRY WHEN ATC GAVE US INSTRUCTIONS TO TURN R TO A HDG OF 280 DEGS. WE DID NOT KNOW WHY; NOR DID WE ASK WHY. WE WERE THEN GIVEN ANOTHER HDG CHANGE TO A HDG OF ABOUT N; THEN FOLLOWED BY A HDG OF 150 DEGS. WE DID A STANDARD RATE TURN OF 25 DEGS; BUT BECAUSE THE WINDS WERE 210 DEGS AT 53 KTS; THAT HDG DID NOT QUITE PUT US ON AN INTERCEPT COURSE WITH THE LOC. THE CTLR MADE SOME KIND OF REMARK TO THE EFFECT THAT HE DID NOT KNOW WHAT WE WERE DOING. WE KNEW WHAT WE WERE DOING; BUT WE DID NOT KNOW WHY ATC WAS HAVING US DO IT. WE PUT 2 + 2 TOGETHER AND WERE ABLE TO FIGURE OUT THAT THE ACFT BEHIND US WAS GAINING ON US. TWR GAVE US A PHONE NUMBER AND ASKED THAT I CALL THE TWR UPON LNDG. I WAS TOLD THAT I SHOULD NOT SLOW DOWN UNLESS I WAS TOLD TO DO SO; AND IF I NEEDED TO SLOW DOWN; I NEEDED TO TELL THEM FIRST. I DO NOT KNOW WHAT ALL THE FUSS IS ABOUT -- WE DID WHAT WE WERE TOLD; ATC DID WHAT HE NEEDED TO DO. AT NO TIME DID WE COME CLOSE TO ANOTHER ACFT; AND WE LANDED SAFELY. SEEMS TO ME THAT EVERYTHING WORKED OUT JUST LIKE IT WAS SUPPOSED TO. SUPPLEMENTAL INFO FROM ACN 568818: PER CLRNC FROM INITIAL APCH CTLR; DSNDING TO 5000 FT; ESTABLISHED ON RWY 13R LOC. A 20 DEG R WIND CORRECTION ANGLE WAS REQUIRED TO TRACK THE LOC. ASSIGNED AND SWITCHED TO FINAL APCH CTLR. CONTACTED FINAL APCH CTLR FOR DFW RWY 13R. APCH CLRNC ISSUED AND READ BACK WAS; 'CLRED ILS RWY 13R; MAINTAIN 4000 FT TO MORRY; SPD 250 KTS TO MORRY; 170 KTS TO THE MARKER.' APCH WAS FLOWN PER CLRNC UNTIL INSIDE MORRY. SPD ASSIGNMENT THEN AMENDED TO 190 KTS. INCREASED SPD TO 190 KTS. SHORTLY THEREAFTER; CTLR ASSIGNED A R TURN HDG 280 DEGS; MAINTAIN 4000 FT; SPD 190 KTS. CLRNC ACCEPTED AND FLOWN AS CLRED. VECTORED BACK TO FINAL APCH HDG AT WHICH TIME ACFT WAS E OF LOC; HDG 130 DEGS ASSIGNED. CTLR INQUIRED IF ARPT WAS IN SIGHT. REPLY WAS IN THE AFFIRMATIVE AND A VISUAL APCH WAS ASSIGNED; HDG 150 DEGS TO INTERCEPT THE LOC; MAINTAIN 190 KTS. THE VISUAL APCH WAS FLOWN AS DIRECTED; ALTHOUGH UPON LOC CAPTURE; A FURTHER R TURN OF 10 DEGS WAS NECESSARY TO ESTABLISH AND TRACK THE LOC. ABOUT THE MARKER; APCH CTLR ADVISED TWR WOULD ISSUE A PHONE NUMBER FOR APCH CTL; RESUME NORMAL SPD AND CONTACT TWR. NOTE: ONCE VECTORED AROUND AND ASSIGNED THE 130 DEG HDG; FINAL APCH CTLR STATED TO ANOTHER ACFT 'THINGS AREN'T WORKING OUT TOO WELL.' FINAL APCH CTLR SEEMED UNAWARE OF THE WIND CONDITIONS ON FINAL.
