DFW ARR DESCRIBED UNUSUAL ATC CLRNC FROM DFW APCH CTLR THAT INCLUDED REMAIN WITH CLASS B AIRSPACE VERBIAGE.

Narrative

ENRTE; BRIEFED AND PREPARED FOR ILS APCH TO RWY 13R. UPON CONTACT WITH APCH CTL CLRED DIRECT TO MORRY FOR THE ILS 13R APCH. SWITCH TO NEW CTLR WHO CLRED US TO DSND TO 7000 FT. AT 7000 FT; THE FOLLOWING CLRNC WAS GIVEN: 'CROSS MORRY AT 4000 FT; CLRED FOR APCH; DO NOT DSND BELOW CLASS B AIRSPACE....' AT THAT POINT WHILE IN HAZE AND LOW VISIBILITY CONDITIONS WITH A YAW DAMPER OUT; WE NOW HAVE TO DETERMINE WHERE THIS AIRSPACE IS. WE PULL OUT THE AIRSPACE PAGE. THE NEXT CALL FROM THIS CTLR IS THAT WE HAVE DESCENDED BELOW CLASS B AIRSPACE. THE NEXT CALL IS FOR ACR Y WHO ARE BEHIND US. THEY HAVE ALSO DSNDED BELOW CLASS B AIRSPACE AFTER BEING THE SAME NONSTANDARD CLRNC. I TRULY BELIEVE AS I DID WHEN FIRST GIVEN THIS CLRNC WHICH I HAVE NEVER HEARD IN OVER 35 YRS OF FLYING THAT THIS PARTICULAR CTLR WAS SETTING US UP. ALL OF THIS CONSPIRED IN PROBABLY LESS THAN 3 MINS. IF THERE IS A PROB WITH THE AIRSPACE TO THE NW THEN LET'S REDESIGN THE APCH WITH STEPDOWN ALTS. WHEN THIS CTLR WAS QUERIED BY MY CAPT AS TO WHETHER THERE WAS A PROB; HIS RESPONSE WAS A 'YES; YOU VIOLATED A CLRNC.' WHEN FURTHER QUERIED AS TO WHETHER THERE WAS A CONFLICT; HE FAILED TO RESPOND. I DISAGREE THE CLRNC IN MY MIND WAS NONSTANDARD. OUR NAVAIDS ARE SET TO THE LOC. THE CONCENTRIC RINGS FOR CLASS B AIRSPACE ARE PREDICATED OFF THE MAVERICK VOR. I WOULD ASK THAT ATC QUALITY ASSURANCE LOOK INTO THE AIRSPACE ISSUE; IE; IS THERE A PROB WITH THE AIRSPACE TO THE NW AND THE ISSUE WITH CLASS B AIRSPACE? IN ADDITION; I WOULD ASK THAT ATC PRO STANDARDS LOOK INTO THE CTLR'S ACTIONS. I BELIEVE HE PURPOSELY DSNDED US AT CERTAIN POINTS TO MAKE SOME SORT OF POINT. IF WE AS PLTS ARE MAKING MISTAKES OUT THERE IN REGARD TO CLASS B AIRSPACE; THE WAY TO FIX IT IS TO BRING IT TO THE ATTN OF OUR PLT GROUP THROUGH THE REPORTING PROGRAM AND OUR ATC LIAISONS. THERE IS NOT A GROUP OF PROFESSIONALS I HAVE MORE RESPECT FOR THAN OUR CTLRS. HOWEVER; YESTERDAY I BELIEVE THIS PARTICULAR CTLR WAS OFF HIS GAME. HAVING PLTS PULL OUT CHARTS DURING LOW VISIBILITY CONDITIONS DURING AN APCH IS A DISTR AND PROBABLY NOT THE SAFEST THING TO DO.
