A80 CTLR DESCRIBED DISPUTE WITH SUPVR ORDERS TO VECTOR ACFT FOR VISUAL APCH DURING QUESTIONABLE VISIBILITY. CTLR RELIEVED FROM POSITION.

Narrative

I WAS WORKING THE N FINAL (V) AT A80. SIMULTANEOUS ILS/PRM APCHS IN USE TO RWYS 8L/9R AND 10. ALL THE FINALS WERE FULL AND QUITE BUSY. WX WAS MARGINAL (EXTREMELY HAZY). ACFT WERE NOT SEEING THE ARPT UNTIL THE FAF. AN SR22 WAS BEING HANDED OFF FROM OUR SATELLITE X POS. SUPVR ADVISED ME TO VECTOR THE ACFT FOR A VISUAL APCH. I EXPLAINED THE SITUATION TO THE SUPVR AND SAID VISUALS ARE NOT WORKING AND I WILL VECTOR THE ACFT FOR AN ILS/PRM 8L. SUPVR ASKED HOW I KNEW THAT A VISUAL APCH WOULDN'T WORK FOR THE ACFT. I EXPLAINED THAT I HAD BEEN WORKING APCH ALL DAY (HR 7 OF AN 8 HR SHIFT); AND VISUALS JUST WEREN'T WORKING TODAY DUE TO THE HAZE. SUPVR THEN ORDERED ME TO VECTOR THE ACFT CLOSE TO THE ARPT FOR A VISUAL. I ADVISED SUPVR THAT UNLESS HE WAS WILLING TO PROVIDE ME WITH VECTORS AND BE RESPONSIBLE FOR THE SEPARATION; THAT I DIDN'T WANT TO DO SOMETHING I CONSIDERED UNSAFE. SUPVR HAD ME RELIEVED FROM THE POS DURING A BUSY TIME; WHICH CREATED AN UNNECESSARY DISTR. SUPVR THEN INTIMIDATED THE NEXT CTLR INTO RUNNING THE ACFT IN CLOSE TO THE ARPT FOR A VISUAL. THE FINAL CTLR HAD TO RUN THE ACFT PARALLEL TO HIS FINAL AND WAIT UNTIL HE WAS ONLY 5 OR 6 MI FROM THE ARPT BEFORE HE SAW HIS TFC. THE ACFT ENDED UP LNDG LESS THAN 2 MI BEHIND HIS LARGE TFC. ALTHOUGH NO OPERROR OCCURRED; THIS OP WAS UNSAFE. THE SR22'S ARE CAPABLE OF MAINTAINING 150 KTS OR SO ON FINAL AND DO NOT REQUIRE EXCESSIVE SPACING BEHIND THEM IF THE SUBSEQUENT ACFT ARE SLOWED TO 160 KTS.
