PHL CONTROLLER VOICED CONCERN REGARDING THE LACK OF TRAINING AND BRIEFING ITEMS REFERENCE DIFFERENT CRDA SPACING PROCEDURES REQUIRED BECAUSE OF THE RUNWAY 35 EXTENSION PROJECT.

Narrative

THIS IS A PROCEDURAL ISSUE INVOLVING THE USE OF THE CONVERGING RWY DISPLAY AID (CRDA) FOR RWY 35 AT PHL. OUR CURRENT FACILITY SOP DESCRIBES THE USE OF WHERE TO VECTOR ACFT IN RELATION TO THE CRDA 'GHOST' TARGET. UNDERSTANDING WHERE TO VECTOR THESE ACFT IS CRUCIAL TO PROVIDING A SAFE; EFFICIENT FLOW OF TFC TO RWY 35. THE FAA JUST POSTED A CHANGE TO THIS PROC IS A 'READ AND INITIAL' BINDER WHICH NOW APPLIES TO EVERYONE INVOLVED WITH THE OP. THE CRDA 'GHOST' TARGET IS NOW OFFSET DIFFERENTLY TO TAKE INTO ACCOUNT RWY 35 EXTENSION PROJECT. UNFORTUNATELY; NO TRAINING HAS BEEN PROVIDED FOR THIS CRDA OFFSET TO THE CTLR WORK FORCE. NO PRE-BRIEFING WAS PROVIDED THE UNION OF THE CHANGE. SEVERAL GAR'S HAVE ALREADY BEEN DOCUMENTED TO DO THE CHANGE IN WORKING CONDITIONS. I FEEL THAT THIS LACK OF TRAINING IN THE NEW PROC HAS RESULTING IN INCREASED WORKLOAD ON THE TWR AND RADAR CTLRS AND CAUSED UNNECESSARY DELAYS TO THE ATC SYSTEM. THE LACK OF TRAINING HAS CAUSED AN INEFFICIENCY TO THE OP AT LARGE AND WITH THE HEIGHTENED USE OF QUALITY ASSURANCE REVIEWS (QAR'S); CTLRS WILL BE MENTALLY TAXED THAT MUCH MORE KNOWING THAT ANY GAR'S WILL BE DOCUMENTED IN THE FACILITY LOG. PROPER TRAINING AND ADEQUATE BRIEFINGS COULD MITIGATE POTENTIAL GAR'S WITH THIS OP.
