Narrative:

We departed runway 28 at yyc. Departure controller instructed us to turn left to 120 degrees and climb to FL250. Passing through 165 degrees we were told to turn right to 180 degrees and level at 9000'. We were passing 7800'. Apparently an air carrier medium large transport was allowed to takeoff on runway 16 and turned right to about 330 degrees. (Runway 28 was current departure runway, wind 240 degrees at 20-25 KTS.) aircraft were allowed to takeoff on separate runways and turned toward each other, resulting in a traffic conflict, which was resolved by turning us out of the way and leveling at 9000' while the other aircraft climbed. Better coordination and planning could have prevented this situation from occurring.

Original NASA ASRS Text

Title: A DEP ACR WAS ISSUED TURNS AND AN ALT RESTRICTION TO ACCOMMODATE ANOTHER DEP FROM ANOTHER RWY.

Narrative: WE DEPARTED RWY 28 AT YYC. DEP CTLR INSTRUCTED US TO TURN LEFT TO 120 DEGS AND CLB TO FL250. PASSING THROUGH 165 DEGS WE WERE TOLD TO TURN RIGHT TO 180 DEGS AND LEVEL AT 9000'. WE WERE PASSING 7800'. APPARENTLY AN ACR MLG WAS ALLOWED TO TKOF ON RWY 16 AND TURNED RIGHT TO ABOUT 330 DEGS. (RWY 28 WAS CURRENT DEP RWY, WIND 240 DEGS AT 20-25 KTS.) ACFT WERE ALLOWED TO TKOF ON SEPARATE RWYS AND TURNED TOWARD EACH OTHER, RESULTING IN A TFC CONFLICT, WHICH WAS RESOLVED BY TURNING US OUT OF THE WAY AND LEVELING AT 9000' WHILE THE OTHER ACFT CLBED. BETTER COORD AND PLANNING COULD HAVE PREVENTED THIS SITUATION FROM OCCURRING.
