Incident at Calgary, AB (ATS operating irregularity)


1997-04-28: Air BC 654, a Dash 8, was on a left hand base for Runway 34, while ACA 851 was on a right hand downwind for the same runway. The controller did not realize that ACA 851 was doing an FMS (Flight Management System) arrival until the a/c turned right base over BARIE. This did not fit the traffic pattern and the controller immediately turned ACA 851 back to the left to continue downwind for separation.
