Narrative:
ATC facility: dfw tower. Location: dfw west runway complex. While awaiting departure for slc, I witnessed dfw tower issue lahso clrncs to a number of aircraft landing runway 18R with a hold short of taxiway B clearance. Surface winds at the time were reported as 350 degrees at 6 KTS and the wind sock adjacent to runway 18L was verifying the north wind. I requested the wind and it was again reported as 010 degrees at 6 KTS. I informed the tower via radio that the lahso was not permitted under our manual and they did stop issuing that clearance. The following day, I returned to dfw from ord and heard the ATIS broadcast ATIS information, XA53Z, wind reported at 350 degrees at 8 KTS landing to the south, lahso in effect, plan to hold short of taxiway B, 8450 ft available on runway 17C. We were the next to last to land to the south. As we contacted dfw tower, they did not issue the actual lahso clearance. Our crews are led to believe this is ok, even though part 1 specifically prohibits a tailwind lahso. We need to have this stopped by towers across the united states and remind our crews of the rules.

Title: S80 CAPT RPT REGARDING THE LAHSO OPS AT DFW WITH TAILWIND EXISTING. WHEN HE SPOKE TO THE TWR ABOUT THE OP, THEY STOPPED IT.
Narrative: ATC FACILITY: DFW TWR. LOCATION: DFW W RWY COMPLEX. WHILE AWAITING DEP FOR SLC, I WITNESSED DFW TWR ISSUE LAHSO CLRNCS TO A NUMBER OF ACFT LNDG RWY 18R WITH A HOLD SHORT OF TXWY B CLRNC. SURFACE WINDS AT THE TIME WERE RPTED AS 350 DEGS AT 6 KTS AND THE WIND SOCK ADJACENT TO RWY 18L WAS VERIFYING THE N WIND. I REQUESTED THE WIND AND IT WAS AGAIN RPTED AS 010 DEGS AT 6 KTS. I INFORMED THE TWR VIA RADIO THAT THE LAHSO WAS NOT PERMITTED UNDER OUR MANUAL AND THEY DID STOP ISSUING THAT CLRNC. THE FOLLOWING DAY, I RETURNED TO DFW FROM ORD AND HEARD THE ATIS BROADCAST ATIS INFO, XA53Z, WIND RPTED AT 350 DEGS AT 8 KTS LNDG TO THE S, LAHSO IN EFFECT, PLAN TO HOLD SHORT OF TXWY B, 8450 FT AVAILABLE ON RWY 17C. WE WERE THE NEXT TO LAST TO LAND TO THE S. AS WE CONTACTED DFW TWR, THEY DID NOT ISSUE THE ACTUAL LAHSO CLRNC. OUR CREWS ARE LED TO BELIEVE THIS IS OK, EVEN THOUGH PART 1 SPECIFICALLY PROHIBITS A TAILWIND LAHSO. WE NEED TO HAVE THIS STOPPED BY TWRS ACROSS THE UNITED STATES AND REMIND OUR CREWS OF THE RULES.
