Incident at Calgary, AB

Summary

1997-05-12: NavCanada 100, a CL-60 Challenger, was flight checking the ILS on Runway 28 and on final, with missed approach instructions to turn right to 030 degrees and remain east of Runway 34. C-GYDE, a Cessna 172 of All-West Air was cleared for takeoff on Runway 34 with instructions to maintain runway heading (340 degrees) and 4500 feet. C-GYDE was observed turning northeast into conflict with NavCanada 100's missed approach path. Two attempts to contact C-GYDE were unsuccessful, so NavCanada 100 was instructed to continue the missed approach turn to 070 degrees. Subsequent radar data revealed that the closest point of approach between the two a/c was about 3 to 4 tenths of a mile within 100 feet. At the closest point, NavCanada 100 was accelerating away from the other a/c. C-GYDE called ATS just after the closest point was passed, about 1 mile northeast of the airport. Weather was 140 broken, 280 broken with 40 miles visibility.
