Aircraft; Procedure
While flying the VUCAN2 arrival into CYYC in NAV mode; we were given a vector by Approach Control and told that we were flying an incorrect track. The nav track in the FMGC did not match the published approach procedure. We entered the correct arrival and approach for Runway 16. The track from the FMGC was incorrect.
The Reporter stated that the FMS VUCAN 2 Arrival to CYYC was properly selected as was the landing runway; Runway 16. However; the track displayed went over the airport before turning around for a south landing. He still does not know how the incorrect track could have been displayed but both pilots were certain about the correct FMGC entries. They did not attempt to troubleshoot the error afterwards.
Flying VUCAN 2 approach; we were given a heading out of CYYZ. This was apparently due to an incorrect heading we were presently flying. Nav track did not match published approach procedure. We corrected; no problems; no traffic.
An Airbus crew entered the CYYC VUCAN 2 arrival with a Runway 16 ILS; but the FMGC flew a track over the airport and did not match the charted VUCAN 2. ATC intervened with vectors for the approach.
