Narrative:

Aircraft landing sea in a north flow at or above 17000', go over eln. In a south flow, they go over over eph on jets, and eat on propellers. Aircraft at and below 16000' can go over eat or eln. Sea flow controller has put out messages that controllers are not to amend changes in routes of flight for aircraft landing sea. Aircraft over eat are handed off to sector 31, over eln handoff to sector 01. If an aircraft is filed over eat sector 31, will have flight plan information--but if the aircraft is reclred over eln, sector 01 does not know the aircraft is coming because flow has restr us not to put the change of route into the computer. This forces a return to manual control vs automation. It is also a hazard to opp direction traffic from the controller who does not have his inbound traffic.

Title: CTLR HAS COMPLAINT ABOUT FAC PROC REGARDING ROUTE CHANGE FOR ARRIVING ACFT.

Narrative: ACFT LNDG SEA IN A N FLOW AT OR ABOVE 17000', GO OVER ELN. IN A S FLOW, THEY GO OVER OVER EPH ON JETS, AND EAT ON PROPS. ACFT AT AND BELOW 16000' CAN GO OVER EAT OR ELN. SEA FLOW CTLR HAS PUT OUT MESSAGES THAT CTLRS ARE NOT TO AMEND CHANGES IN ROUTES OF FLT FOR ACFT LNDG SEA. ACFT OVER EAT ARE HANDED OFF TO SECTOR 31, OVER ELN HDOF TO SECTOR 01. IF AN ACFT IS FILED OVER EAT SECTOR 31, WILL HAVE FLT PLAN INFO--BUT IF THE ACFT IS RECLRED OVER ELN, SECTOR 01 DOES NOT KNOW THE ACFT IS COMING BECAUSE FLOW HAS RESTR US NOT TO PUT THE CHANGE OF ROUTE INTO THE COMPUTER. THIS FORCES A RETURN TO MANUAL CTL VS AUTOMATION. IT IS ALSO A HAZARD TO OPP DIRECTION TFC FROM THE CTLR WHO DOES NOT HAVE HIS INBND TFC.
