Narrative:

Zan approved 2 formation flts of fgt's and their mlt tanker to enter out airspace through a departure gate. This would have placed these aircraft in a position where they would enter and remain in my airspace, which is where their destination, elmendorf AFB is located. Instead, these aircraft entered the approach control airspace in the south radar sector, with the handoff made to our south radar controller. But the aircraft (all 3 flts) were transferred to my frequency. Upon initial contact with both flts of fgt's I coordinated with the south radar controller and issued a heading and descent clearance, immediately followed by a frequency change to south radar frequency. In order to keep sep with the inbound fgt's, the south radar controller was forced to turn an IFR departing small transport to the northeast (away from his normal exiting pointout of our airspace for his route of flight, the small transport ended up going out where the fgt's and the mlt should have entered our airspace). Meanwhile, the tanker was on a nwbnd, converging heading with the small transport (when our south radar controller turned the small transport to miss the first flight of fgt's) the tanker was not visible on his radar scope (too far off the edge of the scope) and reporting in on my frequency. I saw the conflict with the small transport and issued the tanker a swbnd heading and a few seconds later issued another more ssw-erly heading and requested 'best rate of turn for traffic.' sep was maintained (just barely, 3 mi latitude exactly and just a couple hundred ft vertical).

Original NASA ASRS Text

Title: MLT ON A CONFLICTING COURSE WITH AN SMT WAS ISSUED A TURN TO AVOID LOSS OF SEPARATION.

Narrative: ZAN APPROVED 2 FORMATION FLTS OF FGT'S AND THEIR MLT TANKER TO ENTER OUT AIRSPACE THROUGH A DEP GATE. THIS WOULD HAVE PLACED THESE ACFT IN A POS WHERE THEY WOULD ENTER AND REMAIN IN MY AIRSPACE, WHICH IS WHERE THEIR DEST, ELMENDORF AFB IS LOCATED. INSTEAD, THESE ACFT ENTERED THE APCH CTL AIRSPACE IN THE S RADAR SECTOR, WITH THE HDOF MADE TO OUR S RADAR CTLR. BUT THE ACFT (ALL 3 FLTS) WERE TRANSFERRED TO MY FREQ. UPON INITIAL CONTACT WITH BOTH FLTS OF FGT'S I COORDINATED WITH THE S RADAR CTLR AND ISSUED A HDG AND DSCNT CLRNC, IMMEDIATELY FOLLOWED BY A FREQ CHANGE TO S RADAR FREQ. IN ORDER TO KEEP SEP WITH THE INBND FGT'S, THE S RADAR CTLR WAS FORCED TO TURN AN IFR DEPARTING SMT TO THE NE (AWAY FROM HIS NORMAL EXITING POINTOUT OF OUR AIRSPACE FOR HIS ROUTE OF FLT, THE SMT ENDED UP GOING OUT WHERE THE FGT'S AND THE MLT SHOULD HAVE ENTERED OUR AIRSPACE). MEANWHILE, THE TANKER WAS ON A NWBND, CONVERGING HDG WITH THE SMT (WHEN OUR S RADAR CTLR TURNED THE SMT TO MISS THE FIRST FLT OF FGT'S) THE TANKER WAS NOT VISIBLE ON HIS RADAR SCOPE (TOO FAR OFF THE EDGE OF THE SCOPE) AND RPTING IN ON MY FREQ. I SAW THE CONFLICT WITH THE SMT AND ISSUED THE TANKER A SWBND HDG AND A FEW SECS LATER ISSUED ANOTHER MORE SSW-ERLY HDG AND REQUESTED 'BEST RATE OF TURN FOR TFC.' SEP WAS MAINTAINED (JUST BARELY, 3 MI LAT EXACTLY AND JUST A COUPLE HUNDRED FT VERT).
