AN EMB145 PIC RPT ON APCH CTLR TECHNIQUES IN RADAR VECTORS FOR APCH AND THE DEALING WITH A MALFUNCTIONING GS INTO SAV; GA.

Narrative

APCH WAS GIVING TERRIBLE VECTORS TO THE ILS IN USE. WE WERE ON A SECOND APCH AFTER BEING VECTORED IN TOO HIGH THE FIRST TIME TO EVER GET ESTABLISHED. THE SECOND APCH THE CTLR VECTORED US IN WAY TOO CLOSE TO THE ARPT FOR AN IFR APCH. THE ARPT WAS IN SIGHT. THE CTLR WAS UNABLE TO ISSUE A VISUAL CLRNC DUE TO THE TWR RPTING IFR CONDITIONS. WE BECAME ESTABLISHED ON THE ILS CLOSE IN. THE GS BECAME ERRATIC AND STARTED JUMPING UP AND DOWN. THIS CAUSED US TO GET THE AURAL 'GS' WARNING 2-3 TIMES. THE CURRENT 'FLT VISIBILITY' WAS AT LEAST 3500 FT CEILING; AND 5-6 MI VISIBILITY WITH LIGHT TO MODERATE PRECIP. THE WINDS AT THE FIELD WERE ABOUT 5 KTS OUT OF THE N. THE FO AND MYSELF CONFERRED THAT THE GS AT SAV WAS MALFUNCTIONING AND THAT W WERE NOT LOW. SINCE WE WERE IN VFR CONDITIONS; I OPTED TO CONTINUE THE APCH VISUALLY. ON FINAL; I LET THE ACFT GET SLIGHTLY HIGH TO CHK THE GS. IT STILL SAID WE WERE LOW. AT THIS TIME; I COMPLETED A SAFE STABILIZED VISUAL APCH AND LANDED WITHOUT INCIDENT. UPON LNDG WE ADVISED THE TWR OF THE MALFUNCTIONING GS. NOTE: THE ENTIRE APCH WAS CONDUCTED UNDER VFR CONDITIONS. UPON LNDG THE FIELD WAS OBSERVED TO BE VMC ALSO. THE FLT WAS NEVER IN DANGER.
