An air carrier pilot comments that the clt runway 36L hornet.2 SID graphical depiction is misleading because the turn point is 0.3 DME from the runway end while the chart makes the turn point appear further.

Narrative:
We were cleared the hornet.2 departure from runway 36L at clt. According to the SID; we were to maintain a heading of 003 degrees until 2.5 DME off of clt and then turn left to 330 degrees. The captain and I reviewed the SID before takeoff. After takeoff; I reduced the climb rate at 1000 ft AGL and we brought the flaps up. I then looked down at the DME and we were already 3.3 DME from clt; 0.8 DME past the turn point. I started a tentative turn to the left; not quite believing we could already be that far past the turn point. I confirmed that we were in fact past the turn point and I continued the turn to 330 degrees. ATC did not say anything and there was no traffic conflict. After leveling off at cruise; I reviewed the SID again and determined that the turn point is only 0.3 DME past the end of the departure end of runway 36L. The graphical depiction on the SID gives the appearance of maintaining the 003 degree heading for a significant period of time when in fact you have to turn left almost immediately after liftoff. I recommended adding a note to this SID for takeoffs from runways 36L and 36R noting that the required turn occurs immediately past departure end of the runway.

Title: AN ACR PLT COMMENTS THAT THE CLT RWY 36L HORNET.2 SID GRAPHICAL DEPICTION IS MISLEADING BECAUSE THE TURN POINT IS 0.3 DME FROM THE RWY END WHILE THE CHART MAKES THE TURN POINT APPEAR FURTHER.
Narrative: WE WERE CLRED THE HORNET.2 DEP FROM RWY 36L AT CLT. ACCORDING TO THE SID; WE WERE TO MAINTAIN A HDG OF 003 DEGS UNTIL 2.5 DME OFF OF CLT AND THEN TURN L TO 330 DEGS. THE CAPT AND I REVIEWED THE SID BEFORE TKOF. AFTER TKOF; I REDUCED THE CLB RATE AT 1000 FT AGL AND WE BROUGHT THE FLAPS UP. I THEN LOOKED DOWN AT THE DME AND WE WERE ALREADY 3.3 DME FROM CLT; 0.8 DME PAST THE TURN POINT. I STARTED A TENTATIVE TURN TO THE L; NOT QUITE BELIEVING WE COULD ALREADY BE THAT FAR PAST THE TURN POINT. I CONFIRMED THAT WE WERE IN FACT PAST THE TURN POINT AND I CONTINUED THE TURN TO 330 DEGS. ATC DID NOT SAY ANYTHING AND THERE WAS NO TFC CONFLICT. AFTER LEVELING OFF AT CRUISE; I REVIEWED THE SID AGAIN AND DETERMINED THAT THE TURN POINT IS ONLY 0.3 DME PAST THE END OF THE DEP END OF RWY 36L. THE GRAPHICAL DEPICTION ON THE SID GIVES THE APPEARANCE OF MAINTAINING THE 003 DEG HDG FOR A SIGNIFICANT PERIOD OF TIME WHEN IN FACT YOU HAVE TO TURN L ALMOST IMMEDIATELY AFTER LIFTOFF. I RECOMMENDED ADDING A NOTE TO THIS SID FOR TKOFS FROM RWYS 36L AND 36R NOTING THAT THE REQUIRED TURN OCCURS IMMEDIATELY PAST DEP END OF THE RWY.
