A B737-200 FLC SUFFERS A HDG TRACK DEV WHEN THE FO BRIEFS AND FLIES THE WHITESTONE CLB VERSUS THE CONEY CLB. ATC CATCHES ERROR.

Narrative

WE DEPARTED LGA RWY 13. THE CLRNC WAS TO ACCOMPLISH THE CONEY CLB OF THE LGA 8 DEP SID; EXCEPT CHANGE HDG TO 180 DEGS. INSTEAD; WE BRIEFED AND EXECUTED THE WHITESTONE CLB. AS WE WERE IN THE L TURN; DEP CTL ASKED US ABOUT OUR CLRNC; AT WHICH TIME WE REALIZED OUR MISTAKE. IN THE FUTURE; I WILL MAKE IT A PRACTICE TO CONFIRM THE DEP SID; AS THAT DOES NOT APPEAR EITHER ON OUR PRINTED RELEASE OR THE ACARS PDC DISPLAY. SUPPLEMENTAL INFO FROM ACN 401795: THE CLRNC WAS RECEIVED VIA ACARS; EXCEPT THAT THE CLB ASSIGNMENT WAS TO BE ISSUED BY CLRNC DELIVERY. UNFORTUNATELY; FOR REASONS NOT ENTIRELY CLR; I MENTALLY REVERTED TO THE MUCH MORE COMMON WHITESTONE CLB. DURING THE DEP REVIEW/BRIEFING; THOUGH I STATED WE WERE CLRED VIA THE CONEY CLB USING A 180 DEG HDG; I BRIEFED AND SUBSEQUENTLY FLEW THE WHITESTONE CLB WITH A 180 DEG HDG. THE ERROR WAS DETECTED AND BROUGHT TO OUR ATTN BY THE DEP CTLR (FREQ 120.4) WHEN WE STARTED OUR TURN TO THE NE INSTEAD OF INTERCEPTING THE CRI 043 DEG RADIAL AS REQUIRED BY THE CONEY CLB. THE IMMEDIATE QUESTION IS; WHAT CAUSED MY LAPSE OF ATTN? THE 2 MAIN CAUSES WERE HASTE AND MY FAILURE TO COMPLETELY REVIEW ALL THE DATA ON THE LGA 8 SID. THE HASTE CAME ABOUT AS THE RESULT OF A LATE DEP FROM THE GATE CAUSED BY A MINOR MAINT ITEM. REPAIR OF A FAULTY STANDBY HORIZON REQUIRED MECHS TO OCCUPY THE COCKPIT UNTIL AFTER SCHEDULED DEP. THIS; IN TURN; CAUSED AN EXPEDITED BEFORE START CHKLIST AND A SHORTENED REVIEW OF THE SID. THE WHITESTONE CLB IS FAR MORE COMMONLY FLOWN IN OUR OP; BECAUSE MOST OF OUR DEPS ARE TO THE W AND SW FOR WHICH THE WHITESTONE IS TYPICALLY USED. AS A RESULT I FAILED TO SEEK OUT THE TEXT OF THE CONEY CLB; NOT DID I NOTE THE 'CONEY CLB' NOTE IN THE GRAPHIC ADJACENT TO CRI VOR. THIS NOTE IS SEPARATED FROM THE CONEY ALT NOTE. IN ADDITION; THE TEXT DESCRIPTIONS OF THE VARIOUS CLBS ARE NOT CO-LOCATED ON THE SID CHART. THE CONEY CLB TEXT IS ON THE FOLDING PANEL TO THE R OF THE GRAPHIC AND MAY HAVE BEEN FOLDED OUT OF VIEW WHEN I REVIEWED THE GRAPHIC. IT DOES; HOWEVER; POINT OUT ONE DANGER OF PUTTING SO MUCH INFO; DENSELY PRESENTED; IN A SINGLE CHART. WHILE I APPRECIATE THE ECONOMY OF USING A SINGLE PAGE; THE UTILITY OF THIS APCH IS QUESTIONABLE.
