Narrative:

Flight plan constructed of VOR radials/DME fixes, the first of which was the HLC010030. ZMP controller cleared us 'direct to hill city radials.' we had properly loaded and double- checked FMC fix prior to departure. Student loaded FMC and we both agreed fix was correct with double-check. En route to fix, I demonstrated a method to call up fix latitude/longitude as a triple check and discovered that we had loaded HLC100/30 instead of HLC010/30. Advised center of error and made 15 degree course correction. Honest mistake - - computer flight plan format HLC010030 is poor (versus FMC format HLC010/30). Also, controller might have helped catch error by stating HLC0-1-0 radial at 30 DME. Callback conversation with reporter revealed the following information: the reporter was giving IOE instruction for a small scheduled air carrier to another captain.

Title: TRACK DEV.

Narrative: FLT PLAN CONSTRUCTED OF VOR RADIALS/DME FIXES, THE FIRST OF WHICH WAS THE HLC010030. ZMP CTLR CLRED US 'DIRECT TO HILL CITY RADIALS.' WE HAD PROPERLY LOADED AND DOUBLE- CHKED FMC FIX PRIOR TO DEP. STUDENT LOADED FMC AND WE BOTH AGREED FIX WAS CORRECT WITH DOUBLE-CHK. ENRTE TO FIX, I DEMONSTRATED A METHOD TO CALL UP FIX LATITUDE/LONGITUDE AS A TRIPLE CHK AND DISCOVERED THAT WE HAD LOADED HLC100/30 INSTEAD OF HLC010/30. ADVISED CTR OF ERROR AND MADE 15 DEG COURSE CORRECTION. HONEST MISTAKE - - COMPUTER FLT PLAN FORMAT HLC010030 IS POOR (VERSUS FMC FORMAT HLC010/30). ALSO, CTLR MIGHT HAVE HELPED CATCH ERROR BY STATING HLC0-1-0 RADIAL AT 30 DME. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR WAS GIVING IOE INSTRUCTION FOR A SMALL SCHEDULED ACR TO ANOTHER CAPT.
