OCEANIC RTE ALT ASSIGNMENT FOR FORECAST OF PREVAILING WINDS.

Narrative

DAILY; ZOA TFC MGMNT PUBLISHES AT LEAST 3 RTES FROM THE UNITED STATES TO THE FAR EAST. THESE RTES VARY BY FORECAST PREVAILING WINDS. ON NOV/XX/94 RTES WERE PUBLISHED AND FLTS RELEASED ON MOSTLY 1 RTE; R463 TO AXELE THEN DIVERGING N. BEING PART OF THE 'COMPOSITE RTE SYS;' R463 USES NON-STANDARD ALTS (FL300; 320; 340; 360; ETC). FURTHER IT IS A BI-DIRECTIONAL RTE. THIS FORCES TFC INTO A SECTOR NOT DESIGNED TO WORK THE VOLUME AND CREATES SITS BY TRANSITIONING OUT OF COMPOSITE TO STANDARD SEPARATION. IT CAUSED MANY DIFFICULT; UNUSUAL AND POTENTIALLY DANGEROUS SITS THAT WERE UNNECESSARILY CREATED BY THIS EVENT. IN SHORT; THE SECTOR ULTIMATELY RESPONSIBLE FOR SEPARATING THIS HVY TFC FROM SEVERAL XING FLTS DID NOT HAVE CTL OF THE ACFT. FURTHER; BECAUSE ON TRANSITIONING FROM COMPOSITE ALTS AND STANDARD ALTS; AND BECAUSE REDUCED SEPARATION VIA MACH ASSIGNMENTS IS NOT AVAILABLE AT DIFFERENT ALTS (IE; 340 VERSUS 350). THE TASK BECAME EXTREMELY COMPLEX. KEEP IN MIND; THE UNITED STATES FAR EAST FLOW IS RELEASED BASED ON BEING ABLE TO UTILIZE MACH TECHNIQUE; SO THE STANDARD 15 MIN RARELY EXISTS. OPPOSITE DIRECTION TFC ON R463 EXISTED TO CREATE FURTHER SITS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR INDICATED THAT THE USE OF VARYING OCEANIC RTES PERTAINING TO THE FORECAST OF PREVAILING WINDS HAS BEEN STOPPED. RPTR BELIEVES THAT THE SEPARATION STANDARD FOR THESE RTES WILL BE CHANGED THEREBY ELIMINATING ANY OF THE PROBS INDICATED IN THE RPT.
