Narrative:

Misread the commercial chart passing bff put in outbound radial for onl of 076 degree radial. Should have been 066 degree radial outbound. ZDV called us south of course 'you missed your turn.' I checked position I was still somewhat north of 076 degree radial VOR showed 072 degree radial at 40 NM estimate 4 NM south of the 066 degree radial (airway). First officer said he saw me 'somewhat south of course, but thought I was correcting.' after the call we reintercepted centerline and the remainder of the flight was uneventful. At no time were we a traffic conflict. Debrief items with crew: 1) pilots must (at least on my crew) call and check the new radial outbound/inbound. 2) pilots especially glass/INS pilots must use extra vigilance when flying pure 'round dial' aircraft. Finally as a brief to my crew 'don't ever assume I know where I'm going.

Title: B727-200 CREW HAD TRACK DEV IN ZDV CLASS A.

Narrative: MISREAD THE COMMERCIAL CHART PASSING BFF PUT IN OUTBOUND RADIAL FOR ONL OF 076 DEG RADIAL. SHOULD HAVE BEEN 066 DEG RADIAL OUTBOUND. ZDV CALLED US S OF COURSE 'YOU MISSED YOUR TURN.' I CHKED POS I WAS STILL SOMEWHAT N OF 076 DEG RADIAL VOR SHOWED 072 DEG RADIAL AT 40 NM ESTIMATE 4 NM S OF THE 066 DEG RADIAL (AIRWAY). FO SAID HE SAW ME 'SOMEWHAT S OF COURSE, BUT THOUGHT I WAS CORRECTING.' AFTER THE CALL WE REINTERCEPTED CTRLINE AND THE REMAINDER OF THE FLT WAS UNEVENTFUL. AT NO TIME WERE WE A TFC CONFLICT. DEBRIEF ITEMS WITH CREW: 1) PLTS MUST (AT LEAST ON MY CREW) CALL AND CHK THE NEW RADIAL OUTBOUND/INBOUND. 2) PLTS ESPECIALLY GLASS/INS PLTS MUST USE EXTRA VIGILANCE WHEN FLYING PURE 'ROUND DIAL' ACFT. FINALLY AS A BRIEF TO MY CREW 'DON'T EVER ASSUME I KNOW WHERE I'M GOING.
