Incident at CALGARY INTL AB (CYYC) (Conflict - loss of separation)


1997-11-06: C-GTRK took off on Runway 16 at 2347Z for Edmonton City Centre Airport and the crew were assigned the Calgary 7 departure, which included a clearance to climb to 16,000 feet and an assigned heading of 295 degrees. At 2349Z, C-GPOT departed from the same runway for Saskatoon, and the crew were issued a clearance that included a climb to 9,000 feet and a heading of 070 degrees. On the climbout, apparently C-GTRK drifted to the east of runway heading and when the crew turned to their assigned heading of 295 degrees, their a/c crossed the path of C-GPOT which had departed from Runway 16. UPDATE The controller took corrective action by restricting C-GPOT to 6000 feet with an immediate turn to 070 degrees. Separation was reduced to 2 miles and 800 feet, and the weather conditions were VMC.
