HDG TRACK DEV BY DEP TFC.

Narrative

WE RECEIVED AND ACKNOWLEDGED THE LGA 4 DEP WITH MASPETH CLB. AT THE GATE; BOTH RADIOS WERE SET AND THE CLB WAS REVIEWED. UPON TAXI-OUT WE DELAYED ENG START UNTIL REACHING THE RWY. TO OUR SURPRISE; WE ONLY HAD LITTLE TIME TO START THE ENG AND RUN THE CHKLIST BEFORE CLRED FOR TKOF. IT WAS MY LEG AND AS WE SAT IN POS ON THE RWY I AGAIN GLANCED DOWN AT THE DEP AND WROTE DOWN ON MY SCRATCH PAD R 175 AT 2.5 DME L 040. THESE ARE THE INSTRUCTIONS FOR THE WHITESTONE CLB OFF OF RWY 13; NOT THE MASPETH CLB. WE WERE CLRED FOR TKOF AND; UPON REACHING 2.5 DME; I TURNED L TO 040. AT THIS POINT THE CTLR QUERIED OUR HDG AND INFORMED US THAT THE MASPETH DEP WAS A R TURN TO 340. SEVERAL FACTORS; I BELIEVE; LED TO THIS INCIDENT: A MORE THOROUGH REVIEW OF THE RATE(S) RELATING TO DEP SHOULD HAVE BEEN MADE (I.E.; NOT JUST 'WE'VE GOT THE LAGUARDIA 4 WITH MASPETH CLB'). WE SHOULD HAVE GONE OVER THE SPECIFICS AT THE GATE INSTEAD OF WAITING UNTIL WE GOT TO THE RWY. THE CTLR (DEP) ON INITIAL CONTACT CLRED US UP TO 10000 FT. WHILE ISSUING THIS CLB CLRNC WOULD BE A GOOD TIME TO VERIFY OUR INTENTIONS. 'ROGER; CONTINUE CLB TO 10000 FT AND R TURN TO 340.' THIS SIMPLE FOLLOW-UP WOULD HAVE AVOIDED THIS SIT. LOOK AT THE LAGUARDIA 4 DEP PLATE. THERE ARE 3 DIFFERENT CLBS DEPICTED IN THE SPACE OF ABOUT 1 1/4 SQUARE INCHES. ALSO REFER TO THE NARRATIVE DESCRIPTION IN THE LOWER R CORNER. ALL 3 CLBS ARE BUNCHED TOGETHER AND THE WHITESTONE CLB HAS ARROWS BRACKETING IT. IF YOU ARE RUSHED (WHICH WE SHOULDN'T HAVE GOTTEN) AND YOU GLANCE DOWN AT THESE DESCRIPTIONS; YOU CAN SEE WHERE YOUR EYES ARE DRAWN. A SUGGESTION WOULD BE TO MAKE SEPARATE PLATES FOR SEPARATE DEP CLBS TO AVOID CONFUSION. ALTHOUGH 'LEGAL;' BY THE TIME THIS INCIDENT OCCURRED; THE CREW HAD ALREADY BEEN ON DUTY ALMOST 12 HRS AND HAD LANDED. IN ORLANDO; MIAMI; AND LAGUARDIA WE HAD EXPERIENCED ALMOST 30 MIN GATE DELAY AND FATIGUE SURELY COULD HAVE BEEN A CONTRIBUTING FACTOR. IN CLOSING; THIS INCIDENT WAS COMPLETELY UNINTENTIONAL; BUT HAS BROUGHT TO LIGHT MANY FACTORS TO ME WITH REGARD TO ATTN TO DETAILS WHEN YOU'VE HAD A LONG DAY.
