B737 aircraft in cruise. Captain reporter flew out wrong radial after fix. Reporter attributes error to habit pattern of previous flts and lack of controller vigilance. First officer had his VOR on next VOR and, being long distance, accepted the off course indication. Controller intervened and provided vectors when reporter aircraft was intruding on other traffic.

Narrative:
In airline flying we fly the same rtes constantly. I often fly out the 184 degree radial of cae which is J51, and hardly ever go out the 205 degree radial, which is J75. I was exactly on centerline, which made me wonder later why the controller did not notice sooner. It could have been the strong winds out of the west (100+ KTS) causing aircraft to drift over at the turn. I believe there was some complacency on the part of the controller not noticing as with the new aircraft (not our B737-200) always be right on centerline.
Original NASA ASRS Text
Title: B737 ACFT IN CRUISE. CAPT RPTR FLEW OUT WRONG RADIAL AFTER FIX. RPTR ATTRIBUTES ERROR TO HABIT PATTERN OF PREVIOUS FLTS AND LACK OF CTLR VIGILANCE. FO HAD HIS VOR ON NEXT VOR AND, BEING LONG DISTANCE, ACCEPTED THE OFF COURSE INDICATION. CTLR INTERVENED AND PROVIDED VECTORS WHEN RPTR ACFT WAS INTRUDING ON OTHER TFC.
Narrative: IN AIRLINE FLYING WE FLY THE SAME RTES CONSTANTLY. I OFTEN FLY OUT THE 184 DEG RADIAL OF CAE WHICH IS J51, AND HARDLY EVER GO OUT THE 205 DEG RADIAL, WHICH IS J75. I WAS EXACTLY ON CTRLINE, WHICH MADE ME WONDER LATER WHY THE CTLR DID NOT NOTICE SOONER. IT COULD HAVE BEEN THE STRONG WINDS OUT OF THE W (100+ KTS) CAUSING ACFT TO DRIFT OVER AT THE TURN. I BELIEVE THERE WAS SOME COMPLACENCY ON THE PART OF THE CTLR NOT NOTICING AS WITH THE NEW ACFT (NOT OUR B737-200) ALWAYS BE RIGHT ON CTRLINE.
