Narrative:

We departed lfpg runway 27L on the amoga departure; with the first officer flying. As instructed in the company special procedures; the first officer and I were in raw data. I had my VOR tuned to bt (108.8) and a course of 329 degrees set in and the first officer had cgn (115.35) and a course of 266 degrees. On the takeoff checklist when the navigation radios were called; I checked my VOR and looked at the first officer's noting the 266 degree course set on his. Some time after gear retraction and 1900 ft; the first officer started a turn to intercept the 329 degree radial off bt (108.8) and I was surprised to see the deviation bar on my HSI still on the peg and this time I checked the RMI and DME's noticing the radials did not look right and I doublechked the chart. Looking at my VOR setup and the first officer's; I noted his VOR was tuned to pgs (117.05); I immediately reached over and retuned his to the correct VOR cgn (115.35); but we had already deviated off the track and moments later departure called to tell us we were 3 mi east of course. We returned to track as quickly as we could at this time. It appears to me the primary cause of this deviation was a failure to pay attention to detail; and a contributing factor was the depiction of the pgs (117.05) which is not used for any of the departures depicted on the chart. The only place where the pgs VOR is referenced is the MSA which also references the cdg VOR. The depiction of the pgs VOR only introduces an element of possible confusion. Callback conversation with reporter revealed the following information: the captain states that the company's reason for using raw data is to improve navigation accuracy in the early phase of flight. The FMC was loaded with this SID and it was depicted on the navigation display. The aircraft position was accurately displayed on the end of runway 27L as they started their takeoff roll. The first officer got confused when the CDI did not center after takeoff and started his turn early.

Title: B767 CREW DEPARTING LPFG TUNES WRONG VOR FREQ AND DEVIATES FROM SID TRACK.

Narrative: WE DEPARTED LFPG RWY 27L ON THE AMOGA DEP; WITH THE FO FLYING. AS INSTRUCTED IN THE COMPANY SPECIAL PROCS; THE FO AND I WERE IN RAW DATA. I HAD MY VOR TUNED TO BT (108.8) AND A COURSE OF 329 DEGS SET IN AND THE FO HAD CGN (115.35) AND A COURSE OF 266 DEGS. ON THE TKOF CHKLIST WHEN THE NAV RADIOS WERE CALLED; I CHKED MY VOR AND LOOKED AT THE FO'S NOTING THE 266 DEG COURSE SET ON HIS. SOME TIME AFTER GEAR RETRACTION AND 1900 FT; THE FO STARTED A TURN TO INTERCEPT THE 329 DEG RADIAL OFF BT (108.8) AND I WAS SURPRISED TO SEE THE DEV BAR ON MY HSI STILL ON THE PEG AND THIS TIME I CHKED THE RMI AND DME'S NOTICING THE RADIALS DID NOT LOOK RIGHT AND I DOUBLECHKED THE CHART. LOOKING AT MY VOR SETUP AND THE FO'S; I NOTED HIS VOR WAS TUNED TO PGS (117.05); I IMMEDIATELY REACHED OVER AND RETUNED HIS TO THE CORRECT VOR CGN (115.35); BUT WE HAD ALREADY DEVIATED OFF THE TRACK AND MOMENTS LATER DEP CALLED TO TELL US WE WERE 3 MI E OF COURSE. WE RETURNED TO TRACK AS QUICKLY AS WE COULD AT THIS TIME. IT APPEARS TO ME THE PRIMARY CAUSE OF THIS DEV WAS A FAILURE TO PAY ATTN TO DETAIL; AND A CONTRIBUTING FACTOR WAS THE DEPICTION OF THE PGS (117.05) WHICH IS NOT USED FOR ANY OF THE DEPS DEPICTED ON THE CHART. THE ONLY PLACE WHERE THE PGS VOR IS REFED IS THE MSA WHICH ALSO REFS THE CDG VOR. THE DEPICTION OF THE PGS VOR ONLY INTRODUCES AN ELEMENT OF POSSIBLE CONFUSION. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE CAPT STATES THAT THE COMPANY'S REASON FOR USING RAW DATA IS TO IMPROVE NAV ACCURACY IN THE EARLY PHASE OF FLT. THE FMC WAS LOADED WITH THIS SID AND IT WAS DEPICTED ON THE NAV DISPLAY. THE ACFT POS WAS ACCURATELY DISPLAYED ON THE END OF RWY 27L AS THEY STARTED THEIR TKOF ROLL. THE FO GOT CONFUSED WHEN THE CDI DID NOT CENTER AFTER TKOF AND STARTED HIS TURN EARLY.
