Controller at anc reports an operational error when an A320 and 2 F16's lost radar separation due to airspace confign that required a crossover between 2 airports. Reporter states this is a new procedure and is concerned that the same scenario will occur again.

Narrative:

Due to construction on anchorage international airport, anchorage ATCT chose to arrive runway 14. Wind was no factor. Airport reported VFR WX, however, fog bank north of airport required use of runway 14 ILS. Elmendorf required use of runway 05 ILS, a localizer crossing the runway 14 localizer. The locs cross by 90 degrees and the final approach fixes are almost colocated. Aircraft #1, a heavy airbus, was on runway 14 ILS. Aircraft #2, a flight of 2 F-16's, was on runway 05 ILS. Separation was predicated on extreme speed of F-16's and speed restr of airbus. F-16's dragged to 2 mi nonstandard flight. I was not advised. Additionally, f- 16's slowed to same speed as airbus. When I realized conflict was imminent, I advised tower controller to turn aircraft #1. IFR separation was lost. Anchorage runway 14 ILS is new. Traffic management to anc is nonexistent. No procedures exist to de- conflict the 2 ILS (edf runway 5 and anc runway 14) locs.

Original NASA ASRS Text

Title: CTLR AT ANC RPTS AN OPERROR WHEN AN A320 AND 2 F16'S LOST RADAR SEPARATION DUE TO AIRSPACE CONFIGN THAT REQUIRED A CROSSOVER BTWN 2 ARPTS. RPTR STATES THIS IS A NEW PROC AND IS CONCERNED THAT THE SAME SCENARIO WILL OCCUR AGAIN.

Narrative: DUE TO CONSTRUCTION ON ANCHORAGE INTL ARPT, ANCHORAGE ATCT CHOSE TO ARRIVE RWY 14. WIND WAS NO FACTOR. ARPT RPTED VFR WX, HOWEVER, FOG BANK N OF ARPT REQUIRED USE OF RWY 14 ILS. ELMENDORF REQUIRED USE OF RWY 05 ILS, A LOC XING THE RWY 14 LOC. THE LOCS CROSS BY 90 DEGS AND THE FINAL APCH FIXES ARE ALMOST COLOCATED. ACFT #1, A HVY AIRBUS, WAS ON RWY 14 ILS. ACFT #2, A FLT OF 2 F-16'S, WAS ON RWY 05 ILS. SEPARATION WAS PREDICATED ON EXTREME SPD OF F-16'S AND SPD RESTR OF AIRBUS. F-16'S DRAGGED TO 2 MI NONSTANDARD FLT. I WAS NOT ADVISED. ADDITIONALLY, F- 16'S SLOWED TO SAME SPD AS AIRBUS. WHEN I REALIZED CONFLICT WAS IMMINENT, I ADVISED TWR CTLR TO TURN ACFT #1. IFR SEPARATION WAS LOST. ANCHORAGE RWY 14 ILS IS NEW. TFC MGMNT TO ANC IS NONEXISTENT. NO PROCS EXIST TO DE- CONFLICT THE 2 ILS (EDF RWY 5 AND ANC RWY 14) LOCS.
