Narrative:

While working the morning eastbound orient traffic, we have approximately 25 to 35 aircraft eastbound on 2 or 3 airways. During this time, we usually get 33 to 4 aircraft that want to transition across every track (airway) wbound for the orient. This time, the aircraft was further west than normal when we received notice he was coming. A decision was made to descend the aircraft so not to conflict with known traffic. In error, more transfers were taken and the aircraft was not re-evaluated. This has been a major concern of air traffic controllers at the facility. But we've been told there's nothing we can do. We take it from ZOA and get it from tokyo. This was discovered by the pilots reporting the same fix within 2 mins of each other. My suggestion is to not let the aircraft join these airways wbound in the morning past cold bay, that we can see them on radar here and make better decisions on where to merge them with other traffic. Approximately 150 NM west of saint paul island is where our radar coverage ends then it's all non radar.

Title: CTLR HAS LTSS WITH OCEANIC ACFT IN NON RADAR ENVIRONMENT.

Narrative: WHILE WORKING THE MORNING EBOUND ORIENT TFC, WE HAVE APPROX 25 TO 35 ACFT EBOUND ON 2 OR 3 AIRWAYS. DURING THIS TIME, WE USUALLY GET 33 TO 4 ACFT THAT WANT TO TRANSITION ACROSS EVERY TRACK (AIRWAY) WBOUND FOR THE ORIENT. THIS TIME, THE ACFT WAS FURTHER W THAN NORMAL WHEN WE RECEIVED NOTICE HE WAS COMING. A DECISION WAS MADE TO DSND THE ACFT SO NOT TO CONFLICT WITH KNOWN TFC. IN ERROR, MORE TRANSFERS WERE TAKEN AND THE ACFT WAS NOT RE-EVALUATED. THIS HAS BEEN A MAJOR CONCERN OF AIR TFC CTLRS AT THE FACILITY. BUT WE'VE BEEN TOLD THERE'S NOTHING WE CAN DO. WE TAKE IT FROM ZOA AND GET IT FROM TOKYO. THIS WAS DISCOVERED BY THE PLTS RPTING THE SAME FIX WITHIN 2 MINS OF EACH OTHER. MY SUGGESTION IS TO NOT LET THE ACFT JOIN THESE AIRWAYS WBOUND IN THE MORNING PAST COLD BAY, THAT WE CAN SEE THEM ON RADAR HERE AND MAKE BETTER DECISIONS ON WHERE TO MERGE THEM WITH OTHER TFC. APPROX 150 NM W OF SAINT PAUL ISLAND IS WHERE OUR RADAR COVERAGE ENDS THEN IT'S ALL NON RADAR.
