ACR BEING VECTORED; CLRED TO MAINTAIN ALT AND SPD WHEN PASSING THROUGH ALT ASSIGNED. REPLIED UNABLE; CTLR TOOK OFFENSE AND BECAME OFFENSIVE.

Narrative

WHILE BEING VECTORED TO A VISUAL TO 18L; CVG; ATC GAVE US CLRNC FROM 5000 FT TO 3200 FT AS WE TURNED TO INTERCEPT FINAL. SIMULTANEOUSLY WITH PASSING 3500 FT; THE CTLR INSTRUCTED US TO 'MAINTAIN 3500 TILL 8 DME (ILS DME); MAINTAIN 180 KTS TO MARKER; CLRED FOR VISUAL'. SINCE WE WERE PASSING 3500 AT THE TIME; IN A DSNDING L TURN; I REPLIED 'UNABLE'. (TURNS OUT HE MEANT TO SAY 3200 FT.) THE CTLR IMMEDIATELY TOOK BOTH OFFENSE AT; AND ISSUE WITH; MY REFUSAL. 'MAYBE YOU'D BETTER CALL US ON THE GND 'CAUSE YOUR COMPANY HAS AGREED TO THIS PROC FOR NOISE ABATEMENT'. I DECLINED AGAIN; POINTING OUT HIS REQUEST WOULD TAKE ME WELL ABOVE GS; NECESSITATING DSCNT RATES OF 1500-2000 FPM; WHILE SLOWING FROM 180 KIAS; TO CATCH THE GS FROM ABOVE. ALL THIS ON A RWY KNOWN FOR FALSE GPWS TERRAIN WARNINGS AND UNRELIABLE RADAR ALTIMETER READINGS OVER THE RIVER. IRONICALLY; I WAS THEN CLRED LOWER (3000) AND ISSUED CLRNC TO INTERCEPT GS. WHY THIS WAS LESS NOISE OFFENSIVE THAN RIDING GS DOWN FROM 3500 FT; I DON'T KNOW. SEEMS THE 'AGREED UPON' PROC FOR NOISE ABATEMENT IS TO HOLD 3200 FT TILL 8 DME ON THE ILS 18L DME. NORMALLY ASSIGNED 180 KIAS TO MARKER. THIS CAUSES FLYING THROUGH GS; THEN CATCHING IT FROM ABOVE. SINCE OUR COMPANY DICTATES ON GS BY 1000 FT AGL AS PART OF STABILIZED APCH; THIS MEANS HIGH RATES OF DSCNT (AT LEAST 1500-2000 FPM) TO ACCOMPLISH. BAD NEWS ANYTIME; BUT ESPECIALLY ON THIS RWY FOR THE REASONS ALREADY STATED. JUST AS IMPORTANTLY: IT SEEMS A BAD PRECEDENT FOR ATC TO USE 'YOUR COMPANY AGREED TO IT' TO PRESSURE A CREW THAT HAS DECLINED ANY PROC; PARTICULARLY A VOLUNTARY ONE SUCH AS A VISUAL. IN TODAY'S ATMOSPHERE; WHEN ALL PARTIES TO AN INCIDENT/ACCIDENT SCURRY TO AVOID BLAME; THERE IS NO ROOM FOR A CTLR TO PRESSURE A CREW FOR ANY REASON OTHER THAN IMMEDIATE SAFETY; CERTAINLY NOT NOISE ABATEMENT. WOULDN'T SOUND TOO GOOD AT THE INVESTIGATION. MOREOVER; HOW CAN ATC AND MGMNT AGREE TO A PROC THAT THE LINE PLT HASN'T EVEN HEARD OF; MUCH LESS HAD A CHANCE TO THINK THROUGH AND EVALUATE.
