B737-300 ACFT DIDN'T FOLLOW CORRECT SID PROC. ON THE SID DEPICTION THERE ARE 14 DIFFERENT SID ROUTES WHICH RPTR CAPT BELIEVES CAN BE DEPICTED BETTER AND CLEARER.

Narrative

WE WERE CLRED VIA THE ARTHUR KILL DEP AND OUR RTE WAS VIA LANNA. WE ERRONEOUSLY REMAINED ON THE 260 DEG HDG INSTEAD OF INTERCEPTING THE SBJ 100 DEG RADIAL. WHEN WE WERE APPROX ABEAM OF SBJ THE CTLR ASKED WHERE WE WERE GOING AND COMMENTED; 'I GUESS THAT STILL ISN'T DEPICTED VERY CLRLY.' IN OUR RUSH TO GET BACK WHERE WE BELONGED WE INITIALLY PROGRAMMED THE MCP/FMS INCORRECTLY AND INITIALLY TURNED L INSTEAD OF R; FURTHER COMPOUNDING THE ERROR. AT THE SAME TIME THE CTLR HANDED US OFF. THIS CREATED A LOT OF CONFUSION FOR US AND THE NEW CTLR. WE ALL RECOGNIZED AND CORRECTED THE ERRORS AT THE SAME TIME. NO TFC CONFLICTS OCCURRED. COMPLACENCY WAS A DEFINITE FACTOR IN THIS ERROR. WE HAD JUST FLOWN THIS SID ON OUR PREVIOUS DEP FROM EWR AND ASSUMED THE PROC WAS THE SAME FOR ALL DEP FIXES. OBVIOUSLY WE DID NOT TEST THIS ASSUMPTION AS WE SHOULD HAVE. ANOTHER FACTOR IS THAT THIS PROC IS VERY POORLY WRITTEN/CHARTED. I BELIEVE THAT THE CONVENTIONAL METHOD OF DEPICTING SID TRANSITIONS SHOULD BE USED (IE; THE ROUTING VIA SBJ TO LANNA SHOULD BE DEPICTED USING A HVY DASHED LINE AND SHOULD BE REFERRED TO AS THE 'LANNA TRANSITION'). THE CLRNC SHOULD ALSO USE THIS PHRASEOLOGY. ALSO; THE COMMERCIAL CHART CATEGORIZES THIS PROC AS A 'VECTOR' PROC. THIS HELPED STRENGTHEN OUR (INCORRECT) BELIEF THAT WE WOULD RECEIVE VECTORS TO LANNA. PERHAPS THIS PROC SHOULD BE SEPARATED INTO TWO PROCS; ONE FOR THE VECTOR FIXES AND ONE FOR THE PLT NAV FIXES. CERTAINLY SOME CHANGES AND IMPROVEMENTS CAN BE MADE TO THE CURRENT CHART AND CLRNC PHRASEOLOGY.
