Narrative:
ZDV asked if we were on an assigned heading, and I (the PNF) responded 'no, we are on course' (to the bpi (big piney VOR) 035 degree radial at 38 DME fix). At this point we checked the latitude/longitude for this fix on the printed flight plan and compared it with what was programmed into the FMS and found them to be different. Upon further investigation we discovered the fix had been programmed incorrectly during preflight. We should have loaded it as: bpi 035 degree radial 38 DME. Instead it was loaded as: bpi 103 degree radial 38 DME. As the first officer, it is my job to doublechk these loaded points -- I failed to do this correctly. Fortunately, there was no airspace incursion or traffic conflict and ZDV cleared us directly to the original fix. Supplemental information from acn 456366: cleared direct bpi 035 degree radial 38 DME. Incident caused by my misreading bpi 035 degree radial as bpi 103 degree radial.

Title: AN A320 FLC IS ALERTED TO THE FACT THAT THEY ARE NOT PROCEEDING DIRECT TO THE CLRED FIX OF BPI 035 DEG RADIAL 38 DME BY ZDV, CO.
Narrative: ZDV ASKED IF WE WERE ON AN ASSIGNED HDG, AND I (THE PNF) RESPONDED 'NO, WE ARE ON COURSE' (TO THE BPI (BIG PINEY VOR) 035 DEG RADIAL AT 38 DME FIX). AT THIS POINT WE CHKED THE LATITUDE/LONGITUDE FOR THIS FIX ON THE PRINTED FLT PLAN AND COMPARED IT WITH WHAT WAS PROGRAMMED INTO THE FMS AND FOUND THEM TO BE DIFFERENT. UPON FURTHER INVESTIGATION WE DISCOVERED THE FIX HAD BEEN PROGRAMMED INCORRECTLY DURING PREFLT. WE SHOULD HAVE LOADED IT AS: BPI 035 DEG RADIAL 38 DME. INSTEAD IT WAS LOADED AS: BPI 103 DEG RADIAL 38 DME. AS THE FO, IT IS MY JOB TO DOUBLECHK THESE LOADED POINTS -- I FAILED TO DO THIS CORRECTLY. FORTUNATELY, THERE WAS NO AIRSPACE INCURSION OR TFC CONFLICT AND ZDV CLRED US DIRECTLY TO THE ORIGINAL FIX. SUPPLEMENTAL INFO FROM ACN 456366: CLRED DIRECT BPI 035 DEG RADIAL 38 DME. INCIDENT CAUSED BY MY MISREADING BPI 035 DEG RADIAL AS BPI 103 DEG RADIAL.
