1999-05-07: C-GEOS, a Rockwell 690A, and C-GEOG, an Aero Commander 680F, were conducting aerial photo surveys in the vicinity of Slave Lake and had been assigned two separate blocks of airspace, and were operating under Instrument Flight Rules. Edmonton ACC observed one of the a/c infringing on the airspace of the other a/c and the crews were advised that they were heading for one another.

Both crews indicated that they saw the other a/c. Minimum separation requirements for this operation were 5 miles lateral or 1,000 feet vertical. OPI - Enforcement
