Narrative:

Departing ewr on the arthur kill one SID expecting vectors to parke intersection. After takeoff we followed the SID, turned left to 190 degrees, at 2.3 DME to 250 degrees, expecting further vectors. Departure asked if tower told us to intercept the sbj 100 degree radial. I told him we were following the SID, and he again asked if tower told us to intercept the 100 degree radial. I asked him to standby. He said he had traffic for new york, and he gave us a vector and frequency change. After level-out at cruise we studied the SID. I have underlined the part we missed. It was not obvious, and the graphic is misleading. I think the underlined section of the mariner one departure is just as ambiguous.

Title: LGT, WHILE FLYING THE EWR ARTHUR KILL ONE SID, MISREAD CHART AND FAILED TO NOTICE THEY WERE TO INTERCEPT THE SBJ 100 DEG RADIAL. RPTR CITES POOR CHART DESIGN.

Narrative: DEPARTING EWR ON THE ARTHUR KILL ONE SID EXPECTING VECTORS TO PARKE INTXN. AFTER TKOF WE FOLLOWED THE SID, TURNED L TO 190 DEGS, AT 2.3 DME TO 250 DEGS, EXPECTING FURTHER VECTORS. DEP ASKED IF TWR TOLD US TO INTERCEPT THE SBJ 100 DEG RADIAL. I TOLD HIM WE WERE FOLLOWING THE SID, AND HE AGAIN ASKED IF TWR TOLD US TO INTERCEPT THE 100 DEG RADIAL. I ASKED HIM TO STANDBY. HE SAID HE HAD TFC FOR NEW YORK, AND HE GAVE US A VECTOR AND FREQ CHANGE. AFTER LEVEL-OUT AT CRUISE WE STUDIED THE SID. I HAVE UNDERLINED THE PART WE MISSED. IT WAS NOT OBVIOUS, AND THE GRAPHIC IS MISLEADING. I THINK THE UNDERLINED SECTION OF THE MARINER ONE DEP IS JUST AS AMBIGUOUS.
