CTLR STATES THAT NEW PROCS ARE NOT BEING BRIEFED OR PLACED IN THE REF BOOK AT THE SECTOR.

Narrative

AT ZSE THERE HAVE BEEN NUMEROUS INSTANCES OF CHANGES IN PROCS; APCHS AND EQUIP WHERE ADVANCE BRIEFINGS WERE NOT PROVIDED TO THE CTLRS. THE PROB IS THAT THOSE RESPONSIBLE FOR THE CHANGES DO NOT ENSURE THOSE AFFECTED HAVE RECEIVED THE INFO AND ACKNOWLEDGED UNDERSTANDING. LISTED ARE SOME EXAMPLES. 1) A NEW LOA WENT INTO EFFECT BTWN ZSE AND ZLC ARTCCS. THIS INVOLVES A BOUNDARY CHANGE AND A NEW TRANSITION ZONE FOR TRANSFER OF CTL ON ACFT. CTLRS WERE BRIEFED ON THE CHANGE BUT WHEN IT BECAME EFFECTIVE; THE OLD LOA WAS STILL THE ONLY REF MATERIAL AVAILABLE AT THE SECTOR. THE C AREA BINDER WAS UPDATED WHEN A SECTOR CTLR ALERTED SUPVR. 2) AT THE END OF MAR THE EAT VOR WAS RECALIBRATED FOR MAGNETIC VARIATION RESULTING IN A 3 DEG SHIFT. THIS RESULTED IN A SHIFT IN RADIALS FOR THE AIRWAYS; APCHS AND SECTOR CTL POINTS. IT WAS LEFT TO CREW SUPVRS TO WARN CTLRS OF THE CHANGES. AS OF MAY XX; SOME CTLRS WERE STILL UNAWARE OF THE CHANGES. NEW CHARTS REFLECTED THE CHANGES APR XX. 3) ALSO ON APR X; A NEW MISSED APCH BECAME EFFECTIVE FOR THE NDB-A AT LGD. THE NEW PROC HAD THE ACFT ENTERING ANOTHER CTR'S AIRSPACE AND HOLDING OVER A VOR (BKE); 25 MI FROM LGD ARPT. NEITHER ANYONE AT ZSE NOR ZLC WAS AWARE OF THE CHANGE! IT WAS NOTICED FIRST BY A SECTOR CTLR ON MAY XX. CTLR MUST MEMORIZE MUCH OF THE DATA NEEDED TO RUN A SECTOR EFFECTIVELY. CHARTS; MAPS; PROC BINDERS ARE REFERRED TO ONLY AS MEMORY AIDS. JUST PUTTING A CHANGE IN A BOOK OR ON A CHART IS NOT SUFFICIENT TO INFORM CTLRS OF A CHANGE. A BRIEFING BEFORE AND AFTER WITH ENSURING FEEDBACK AND ACKNOWLEDGEMENT FROM CTLRS IS NECESSARY.
