ACR SMT FLEW WRONG RTE AFTER DEP CDR.

Narrative

FOR PART OF AUGUST; FLTS FROM CDR TO BIS WERE FILED BY FLCS DUE TO THE CHANGE OF SCHEDULING AND ABSENCE OF NEW FLT PLANS IN THE ATC SYS. I RECEIVED CLRNC FROM ATC VIA FSS (COLUMBIA RADIO) AS 'CLRED TO BISMARCK VIA V169' ETC. BOTH THE CAPT AND MYSELF ASSUMED V169 WAS CDR-DPR-BIS; LIKE THE FLCS HAD BEEN FILING PREVIOUSLY. UNFORTUNATELY; NEITHER OF US CONFIRMED THIS VERBALLY OR BY USE OF THE CHARTS. WE DEPARTED CDR AND REQUESTED A HDG DIRECT BIS UPON CONTACTING ZDV. THE CTLR RESPONDED BY SAYING HE WAS TOO BUSY AT THE MOMENT AND ASKED US TO CONTINUE FLYING OUR FILED RTE. WE THEN FLEW A HDG FOR DPR STILL THINKING THAT WAS OUR ROUTING. AFTER A FEW MOMENTS; THE CTLR ASKED US TO CONFIRM WE WERE PROCEEDING DIRECT TO RAP. OUR ANSWER WAS 'NEGATIVE; WE'RE PROCEEDING DIRECT TO DPR.' AT THIS POINT; THE CTLR BECAME VERY ANGRY AND TOLD US TO BE ADVISED OUR ROUTING WAS V169 WHICH IS CDR-RAP-DPR-BIS. THE CTLR ALSO STATED ANY FUTURE DEVS WOULD NOT BE TOLERATED. I SEE 2 WAYS IN WHICH THIS SIT MAY BE AVOIDED IN THE FUTURE. ONE IS TO HAVE OUR FLCS CHK WITH OPS AS TO THE PLANNED ROUTINGS OF NEW FLTS IN CASE THE FLC MUST FILE THEM UNTIL THEY ARE PUT IN THE ATC SYS. THE OTHER PREVENTIVE METHOD IS FOR THE FLC TO CONFIRM; EITHER VERBALLY OR BY USE OF CHARTS; ANY UNFAMILIAR RTE. THE LATTER OF THESE PREVENTED AN EXACT REPEAT OF THIS INCIDENT 2 NIGHTS LATER WHILE I WAS FLYING WITH A DIFFERENT CAPT. SUPPLEMENTAL INFO FROM ACN 344977: THE MAIN CONTRIBUTING FACTOR WAS EACH CREW MEMBER'S UNFAMILIARITY OF THE AREA AND ASSUMPTION OF WHAT THE CORRECT CLRNC WAS.
