Narrative

ASSIGNED TO MAINTAIN 300 KIAS BY ZFW PRIOR TO BONHAM THREE ARR. WAS NEVER TOLD TO EITHER COMPLY OR TO DELETE THE LISTED SPDS ON THE STAR. 8 NM PRIOR TO KARLA INTXN; FO; PF; SLOWED ACFT TO 250 KIAS IN ORDER TO COMPLY WITH THE 250 KTS AT KARLA RESTR LISTED ON THE STAR. CTR THEN ASKED CAPT; PNF; OUR AIRSPD. WHEN TOLD 250 KIAS CTR REPLIED YOU WERE TOLD TO MAINTAIN 300 KTS; I HAVE ACFT RUNNING OVER THE TOP OF YOU. SWITCH TO APCH 125.02. NO TCASII ALERT OCCURRED OR LOSS OF SEPARATION THAT WE WERE AWARE OF. IT WAS OUR UNDERSTANDING; THE CAPT AND FO; THAT WE WERE TO MAINTAIN OUR LAST ASSIGNED SPD; UNTIL WE NEEDED TO SLOW IN ORDER TO COMPLY WITH THE SPDS ON THE STAR; DUE TO THE CTR NOT GIVING US EITHER TO COMPLY WITH THE SPDS; OR TO DELETE THE SPDS ON THE STAR. THE BONHAM 3 STAR STATES AT KARLA INTXN TO MAINTAIN 250 KTS AND TO EXPECT 11000 FT. WE DO NOT FEEL WE DID ANYTHING INCORRECT AND WOULD DO THE SAME PROC AGAIN. SUPPLEMENTAL INFO FROM ACN 411561: DURING DSCNT ON BONHAM THREE ARR; WE WERE TOLD TO MAINTAIN 300 KTS FOR TFC FLOW TO DFW. DFW WAS LNDG TO THE S; RWY 17C. WE WERE TOLD BY ATC TO CROSS KARLA AT 11000 FT; EXPECT RWY 17C. OVER BYP AT 11000 FT; WE SLOWED TO 250 KTS PER THE ARR TO BE OVER KARLA AT 250 KTS. APCH CTLR ASKED US OUR SPD; AND WE SAID 250 KTS. CTLR BECAME UPSET THAT WE HAD SLOWED AND JAMMED UP TFC BEHIND US; WITHOUT CLRNC TO SLOW. WE WERE VERBALLY CHASTISED AT LENGTH BY APCH CTLR OVER BYP. WE WERE NEVER TOLD THAT THE SPD RESTR AT KARLA WAS WAIVED. WE ASSUMED THAT WE WERE TO COMPLY WITH THE SPD REDUCTION PER THE ARR.
