Narrative:
ATIS reported winds 210 degrees at 7 KTS with a 3700 ft overcast. Approach requested 180 KTS to the marker and the crew complied. Upon GS intercept, it took approximately 15-20 degrees of correction to maintain the localizer. The tower immediately notified of windshear advisories upon check-in with surface winds 300 degrees at 15 KTS gusting to 30 KTS. The crew was barely able to meet stabilized approach criteria. I felt that ATC (approach control) was asking too much of this crew and the crew probably should have taken the initiative to say 'unable' to the speed request.
Original NASA ASRS Text
Title: B737 CREW ON RWY 31R ILS APCH INTO DFW WERE NOT COMFORTABLE WITH THE 180 KT SPD TO THE MARKER INSTRUCTION FROM ATC.
Narrative: ATIS RPTED WINDS 210 DEGS AT 7 KTS WITH A 3700 FT OVCST. APCH REQUESTED 180 KTS TO THE MARKER AND THE CREW COMPLIED. UPON GS INTERCEPT, IT TOOK APPROX 15-20 DEGS OF CORRECTION TO MAINTAIN THE LOC. THE TWR IMMEDIATELY NOTIFIED OF WINDSHEAR ADVISORIES UPON CHK-IN WITH SURFACE WINDS 300 DEGS AT 15 KTS GUSTING TO 30 KTS. THE CREW WAS BARELY ABLE TO MEET STABILIZED APCH CRITERIA. I FELT THAT ATC (APCH CTL) WAS ASKING TOO MUCH OF THIS CREW AND THE CREW PROBABLY SHOULD HAVE TAKEN THE INITIATIVE TO SAY 'UNABLE' TO THE SPD REQUEST.
