Narrative:

Drake 4 departure, phx SID. Departed runway 8R. Climbed on 070 degree heading. At 4 DME of srp VOR SID depicts aircraft to be at or below 3000'. I called this out to the copilot's attention, who was flying, as we approached 3000' just outside of 4 DME. At 1 DME, SID depicts at 030 degree heading. Upon contact with phx departure control, we were cleared to climb to 15000'. As we passed through the srp 330 degree right, the copilot initiated a left turn to intercept that radial. At approximately 10200-10500', departure control questioned our heading. I responded that we were intercepting the 330 degree right. Departure control said to turn right to 360 degree heading. Contributing factor to this is that our normal departure would be the payso 6 departure SID. This is very similar to the drake 4, with the exception that at 1 DME of srp (VOR), you turn to a heading of 040 degrees to intercept the 030 degree right of srp. The drake 4 is similar, with the exception that at 1 DME of srp (VOR), turn left to a heading of 030 degrees and in small, non-highlighted print in the instructions for the departure it states, 'for vector to salt river 330 degree right report to maier intersection.' I suggest that there be greater emphasis on the pictorial view of the drake 4 departure, along with bold letters emphasizing to not intercept the radial, but to maintain the 030 degree right for vectors.

Title: ACR FLT CREW CITES DEFICIENCY IN AERO CHART PRESENTATION SID AS REASON FOR HEADING TRACK DEVIATION OUT OF PHX IN A NIGHT OPERATION.

Narrative: DRAKE 4 DEP, PHX SID. DEPARTED RWY 8R. CLBED ON 070 DEG HDG. AT 4 DME OF SRP VOR SID DEPICTS ACFT TO BE AT OR BELOW 3000'. I CALLED THIS OUT TO THE COPLT'S ATTN, WHO WAS FLYING, AS WE APCHED 3000' JUST OUTSIDE OF 4 DME. AT 1 DME, SID DEPICTS AT 030 DEG HDG. UPON CONTACT WITH PHX DEP CTL, WE WERE CLRED TO CLB TO 15000'. AS WE PASSED THROUGH THE SRP 330 DEG R, THE COPLT INITIATED A LEFT TURN TO INTERCEPT THAT RADIAL. AT APPROX 10200-10500', DEP CTL QUESTIONED OUR HDG. I RESPONDED THAT WE WERE INTERCEPTING THE 330 DEG R. DEP CTL SAID TO TURN RIGHT TO 360 DEG HDG. CONTRIBUTING FACTOR TO THIS IS THAT OUR NORMAL DEP WOULD BE THE PAYSO 6 DEP SID. THIS IS VERY SIMILAR TO THE DRAKE 4, WITH THE EXCEPTION THAT AT 1 DME OF SRP (VOR), YOU TURN TO A HDG OF 040 DEGS TO INTERCEPT THE 030 DEG R OF SRP. THE DRAKE 4 IS SIMILAR, WITH THE EXCEPTION THAT AT 1 DME OF SRP (VOR), TURN LEFT TO A HDG OF 030 DEGS AND IN SMALL, NON-HIGHLIGHTED PRINT IN THE INSTRUCTIONS FOR THE DEP IT STATES, 'FOR VECTOR TO SALT RIVER 330 DEG R RPT TO MAIER INTXN.' I SUGGEST THAT THERE BE GREATER EMPHASIS ON THE PICTORIAL VIEW OF THE DRAKE 4 DEP, ALONG WITH BOLD LETTERS EMPHASIZING TO NOT INTERCEPT THE RADIAL, BUT TO MAINTAIN THE 030 DEG R FOR VECTORS.
