AN ACR CL65 FO RPTS THAT THE CAPT HAD PROGRAMMED THE FMC TO FLY THE WRONG RTE BY ENTERING A DIRECT RTE VS THE STAR RTE TO THEIR DESTINATION.

Narrative

CAPT WAS FLYING THIS LEG FROM CVG-MCO. ROUTING TOOK US FROM SZW VOR TO PIE VOR AND THEN THE MINEE 3 ARR INTO MCO. THIS IS AN UNUSUAL ROUTING FOR US; AND CAPT HAD MANUALLY PROGRAMMED THE FMS FOR THIS FLT. MY SUSPICION IS THAT AFTER PIE VOR; HE SIMPLY TYPED IN MINEE; AND SO THE FLT PLAN IN THE FMS HAD US FLY FROM PIE DIRECT TO MINEE INTXN AND THEN TO MCO. HE SHOULD HAVE SELECTED MCO ARRS; AND THEN SELECTED THE MINEE 3 ARR. THAT WAY; THE FMS WOULD HAVE PLANNED US TO FLY THE CORRECT ROUTING FOR THE MINEE ARR. WE DID NOT CATCH HIS ERROR AND AFTER PIE VOR; CTR ASKED US TWICE ABOUT OUR ROUTING. HE SAID THAT A COMPANY AIRPLANE HAD MADE THE SAME MISTAKE THE NIGHT BEFORE; AND THEY HAD ALMOST HAD A CONFLICT. WE DID NOT HAVE ANY CONFLICT (AS FAR AS I KNOW) AND NO EVASIVE ACTION WAS TAKEN. SUPPLEMENTAL INFO FROM ACN 401203: CTR TOLD US TO DSND TO CROSS PIE VOR AT FL210. BY THE TIME WE CROSSED PIE VOR WE WERE STILL DSNDING THROUGH FL225 ON THE WAY TO FL210. I QUERIED THE CAPT ABOUT THE XING RESTR ABOUT 10 MI BEFORE PIE VOR; AND HE REPLIED THAT HE WAS NOT AWARE OF ANY XING RESTR. HE DID NOT HEED MY ADVICE ON THE MATTER. ATC WAS BUSY AT THE TIME; SO I COULD NOT VERIFY THE SIT WITH THEM ON THE RADIO. THE NEXT TIME THIS OCCURS; I WILL BE MUCH MORE ASSERTIVE IN VERIFYING MY OPINIONS ABOUT THESE MATTERS.
