P31 CTLR EXPRESSED CONCERN REGARDING NPA GCA CTLR'S UNWILLINGNESS TO ACCEPT A FLT FOR GCA OR TACAN APCH WITH DECREASING WX CONDITIONS.

Narrative

NPA WAS RPTING 2000 FT SCATTERED; BUT HAD JUST CALLED AND ADVISED THAT THEY WOULD NOT ACCEPT AND BREAK OVERHEAD TFC. I HAD A FLT OF 2 F-18'S INBOUND FROM THE W REQUESTING A VISUAL STRAIGHT-IN APCH. I ASKED NPA ATCT IF THEY THOUGHT THAT THE F-18'S COULD GET IN ON A STRAIGHT-IN VISUAL AND THE TWR SAID YES. I DSNDED THEM TO 1500 FT (MVA); BUT THEY DID NOT PICK UP THE FIELD UNTIL APPROX 3 MI OUT; AND THEY REQUESTED TO BE BROKEN OUT AND VECTORED FOR A SECTIONED PAR APCH. I TOLD NPA WHAT THEY WERE GOING TO DO AND VECTORED THEM OUT FOR THE PAR NPA; THEN CALLED OVER AND SAID THEIR CEILING WAS NOW 700 FT BROKEN. I VECTORED THE F-18'S OUT; TURNED THEM TO FINAL; AND WHEN HANDING THEM OFF TO GCA; I ADVISED THAT THEY WANTED A SECTIONED PAR. GCA SAID UNABLE SECTIONED APCH DUE TO WX; AND THAT I WOULD HAVE TO SPLIT THEM UP. I BROKE OUT THE 2 ACFT AGAIN AND TOLD THEM. THE LEAD PLT SAID THEY WOULD NOT SPLIT UP AND REQUESTED VECTORS FOR A TACAN RWY 7R APCH. I VECTORED THEM BACK OUT (AS A FLT) AND CLRED THEM FOR THE APCH. I AGAIN HANDED THEM OFF TO GCA FOR FINAL MONITOR (IN ACCORDANCE WITH LCL LOA). GCA CALLED AND SAID THE CEILING WAS NOW 200 FT OR 300 FT BROKEN; THAT THE FLT COULD NOT EXECUTE THE APCH AND TO BREAK THEM OUT AND SPLIT THEM UP. PLT SAID HE WOULD NOT SPLIT UP AND WANTED TO CONTINUE THE APCH. OUR SUPVR CALLED NPA GCA; ADVISED HE WAS DECLARING AN EMER FOR THE FLT; AND THEY WERE DOING THE TACAN APCH. FLY CONTINUED AND LANDED WITHOUT INCIDENT. WE NEVER RECEIVED OFFICIAL NPA WX UNTIL AFTER ALL THIS HAPPENED. THEY WERE STILL SHOWING 2000 FT SCATTERED. AFTER THEY LANDED; HE CALLED US AND THANKED US AND TOLD US HIS WING MAN DID NOT HAVE THE SAME RATING AND THAT IS WHY HE WOULD NOT SPLIT HIM OFF. IF THE PLT WANTED TO SHOOT THE APCH; THEN NPA GCA SHOULD NOT HAVE TRIED TO DENY IT. THE LACK OF TIMELY; ACCURATE WX AND THE INCREASE COORD REQUIRED CREATED AN UNSAFE SIT FOR BOTH ACFT AS WELL AS THE OTHER ACFT I WAS WORKING ON FINAL AT THE TIME.
