PURPOSE.

This order provides criteria and guidance for constructing and operating simultaneous offset instrument approaches to parallel runways spaced at least 750 ft apart, and less than 3,000 ft apart at airports identified by the FAA for SOIA. This order establishes criteria for conducting closely spaced parallel operations, and identifies procedural requirements to ensure safety. Implementation of SOIA procedures requires additional analysis and study at most locations. Specific aircraft handling procedures used to implement the operational objectives described in this order are the responsibility of the Air Traffic Organization (ATO) and are contained in various ATO directives.
